Title: This Is The EPIC Soggs 92K75 MAGA Thread
Post by: Soggz on January 04, 2019, 06:43:11 PM
Hi. I recently bought a k75c that had been parked since 2008.
It was sat in a guys garage. I got it home,had to put a new fuel pump and rubber housing in it,as it had turned to black jam and blocked the pump.
Put the new set up in,and it started. Albeit a bit rough,but it works. The indicators worked,there was a pop,and now they don't. Admittedly,it's hard to start,but it does start. Also,I let it run for about 15 mins,and noticed the temp light came on,the fan never,and water was coming back into the overflow resavoir bottle(?) by the battery.
I have no real idea about these k bikes apart from they seem to have a lot of electrics on them. I have recently rebuilt a cx500 Eurosport which I turned into a street brat cafe racer type thing,so I know mechanics.
Please,any help would be great,as I have never played with fuel injection systems on a bike before.

Hi,I have recently bought a k75c.
77,000 miles on the clock,but garaged since 2008.
I put in another fuel pump,filter,lines seemed OK. It started second press of the button after opening and closing the choke a few times!
The indicators worked up to that point,then 'pop'!,and then they didn't,but the horn still does,so not the fuse?
Also,today,I ran it for around 110 mins or so,the temp light came on,the fan never,and water came back through to the expansion bottle by the battery. The fan isn't,I don't think,seines,as it's easy to move with my finger.It dosnt spin really loosely,but it moves fairly freely on its own,but dosnt come on.Any help would be great.
Thanks in advance.

Flush the cooling system, get rid of the thermostat, or better yet, determine if it is working (if you know mechanics, you know how to do it), and try again. If that fails solve the overheating issue, then you have problems in the fan starting circuit. Lots of guys on this forum know how to diagnose it.

Good luck.

a rather lengthy article but should nail down whatever ails your fan; https://ibmwr.org/index.php/2007/06/01/cooling-fan-diagnostics/

My fan rarely comes on in normal riding, usually on a hot day stuck in traffic when you can really appreciate that blast of hot air beneath you.

Thank you sir, for your reply. Itís all new to me, so Iím scratching my head on this a bit. I just thought the fan would have come on before the temp light. I guess, at least the temp sensor is working, which is good.
Any help is good.

Oil.
What's the best to use?
I recently changed out my oil in my k75c.
It had been sat since 2008, so it was a bit thin,so to speak. Now.I went to our local car shop,Halfords,and all they really had was semi synthetic,synthetic oils for £40.00, which is quite expensive.
I went to another car parts shop here,and they were selling 20w50 Mineral oil for only £17.00 for 5 litres.
I here for older bikes that pure mineral oil is better for bikes with dry clutches. Is it ok to use this,and save myself,what I consider,a considerable amount of money over time?
Thank you in advance.

After a quick look at the schematics....

Turn signal controller is fed with 2 power circuits. Fuse #7 for the "controls electronics" and fuse #3 for switched lamp power.
Horn relay is powered from fuse #7.
The fan controller has 2 circuits feeding it as well. Fuse #6 for controls and Fuse #7 for motor power.

FYI since these bikes are fuel injected, they have no "choke" butterfly. The lever marked choke, simply opens the throttle....

Thank you. So Iíll go with the cheaper oil for my pocket. Oh, and you ever use duck eggs for scotch eggs? Very nice. Much richer. My mother makes them for me. More of a meal, as bigger.

Thank you,sir. I will renew all fuses tommorow when it is light. Hopefully, that will solve my problem.Also, re: no choke. Yes, I sort of worked that one out when opening the lever out and looking at the throttle cables.

The fan STILL never came on...

Brick fans are prone to seizure unless exercised occasionally. The OEM fan also has a tendency for the brush holders to melt.  You should be able to get a finger in and spin the blades, if they don't spin an aftermarket fan can be fitted. A lot of inmates also wire  in an override switch which can be used to check the condition of the fan.

I have fitted my brick with a lit override switch. At least once a week I give it a test. I also turn it on when encountering heavy traffic especially in summer.
My brushes melted 20 years ago so i ended up modifing a Davies Craig fully sealed fan which is stilling going strong. The Spal as proposed by Gryph is a good modification and the way to go if your fan is stuffed. The OEM fans were'nt the best design and I would'nt bother refitting one.

Good evening, sir.
Yes, unfortunatly, my brush holder on one side, too, has melted. What is this replacement fan you speak of?
I quite like the idea of it being on a separate switch, but can it also plug straight in to the exsisting loom as it it?
Electrics arnt my strong point, unfortunatly. Also, are the fans available here in the UK?
 Thanks in advance.

Surfleet is a long ways to drive from Sommerset, but Motobins.com is located there. They are great for getting parts, and quite responsive to questions. Good luck with the fan, and "yes" Motobins has them in stock, but be prepared for sticker shock! We'll just blame it on Brexit. ;)

Thank you, I really appreciate your help. But which one do you advise me to purchase, as they seem to be different amps? I know the size, 6.5", but not sure of the power(?).

Also,how would one attach it? Would it be cable (zip) ties through the radiator,or do they fit in the original surround?
I did see the links above,but I just wanted some assurance.
Thank you.

Post by: Soggz on January 07, 2019, 02:34:13 PM
I can assure you that cable ties through the radiator weren't used in those photos but pop rivets through the original housing were used. Look more closely at the photos. The original housing was split on one side then stretched open to accommodate the new fan. The fan was then riveted to the old housing. See it?
Ah yes,I see them now! What a brilliant idea! Well done, to think of that. I shall order one immediately. But back to my previous question,which fan should I order? I know it's the 6.5", but which ampage,or does it not matter?

I had the brush holders melt on my K100RS.  I tried to fix them, but the fix only lasted a couple thousand miles.  Here is exactly the fan I used:

https://www.ebay.com/itm/Spal-30100402-6-5-Straight-Blade-Low-Profile-Fan-Puller-325-cfm/312248815224?epid=1172534759&hash=item48b37ace78:g:7TIAAOSw4NZbdZSc:rk:1:pf:0#shpCntId

I would do a buy it now and see if the transaction is blocked because of your address.  Worse comes to worse, someone here could purchase it and ship it to you.  It woudn't be the first time.

I have linked above the procedure I used to install it.  Avoid cable ties, they aren't reliable enough.  Follow the procedure I linked.  It is really easy and holds up, my installation has gone through 15,000 miles and a bad accident and still works.

While the radiator and fan are off the bike take the opportunity to clean the radiator thoroughly inside and out.  Even if the internal passages are squeaky clean, there usually is enough dirt and bugs in the fins to block almost all the air flow.

The one you show is not the same as the one I used, the blades look different, and who knows what else may not be the same.  The one I linked is the one I used and I know it works.

I used a band saw to cut all the tabs and slots off the frame.  A hacksaw will work too.  Then I cleaned them up with an 80 grit sanding disc on a drill.

check out reply #18 by RoadBandit to see how to do the retrofit. If you are mechanically competent to get the fan and radiator out of the bike the retrofit's a piece of cake.

The test is performed between one of the terminals and the body of the sensor. On installation do not use Teflon tape or any form of sealant around the threads. Thread tape or sealants could act as an insulator.

Put enough boiling water into a cup to immerse some of the probe. Immerse some of the probe. Be careful. Boiling water is hot.  Put a thermometer into the water. Be careful. Some old thermometers have mercury in them and if you eat it, you will go crazy.Take one lead and touch the screw threads; touch one of the plug blades with the other, as Martin has already indicated. Be careful. If somebody sees you doing this, they might call the authorities because they think you're involved in terrorist activities. Follow rbm's chart. Compare the resistance value on your multimeter with the one on the chart as the water cools.

And my 1972 vw camper.

hah, OK, the camper van is a good starting point in understanding the difference between Japanese and German engineering :) Also whilst visiting the VW place, you might want to pick up some vacuum lines, the one, they sell for the beetle/camper van with the inside dia of 3.5mm and the outside covered in braided cloth is a perfect fit for the vacuum line between the throttle body and the fuel regulator. Needless to say, for the fraction of the BMW price it is a lot higher spec'd as the braided outer layer protects the rubber (and it fits inside the anti-kink spring just tightly). I have bought 2 metres of that line for less, what BMW would have charged me for 30cm of their own line and I have had good use elsewhere of the left over 1.7 metres.

Yes, sorry.

It's a straight-forward connection and measurement process.

1. Use an alligator clip to attach the postive test lead (red) to the tab on the sensor and another alligator clip to attach the negative test lead (black) to the body of the sensor.  If you can't conveniently find a large enough clip, twist bare wire around the body and make sure it is very secure; then attach the lead to the bare wire.

2. Set the meter on Ohms (Resistance) setting.  Most modern digital multimeters had automatic range selection so no need to set a range.  If yours doesn't have autoranging, then set it on the 1000 Ohm range.

3. As Laitch instructed, place the sensor in the boiling water along with the thermometer, with the multimeter on.  The reading should quickly start to drop.

4. When the multimeter reading has stabilized, then start to read both the multimeter and the thermometer at the same time as the water cools.  The temperature should be dropping and the multimeter reading should be rising.

Ah,ok. The guy on the vid put his meter prongs both on the 2 connections, one on each,put the sensor in the water,and the number on the meter went down. Is that right? The sensor must work though,as when I wrote earlier,I ran the bike,it got hot,the temp light came on,but the fan never. So that means it works then?
I do apologise,as electrics are like unexplained magic to me! I,e, I can quite happily build you an engine,but you would have to get someone to wire it up. I must try harder.lol

The temp sensor for a classic K consists of two NTC thermistors housed in a single threaded plug, the body of which forms a common connection between the two.  If you test between both tabs (as in the video which I didn't watch), then they're measuring incorrectly.  One thermistor is for controlling the fan, the other is for feeding the ECU engine temperature information.  It's quite possible that one side of the temp sensor is functioning and the other is broken.  The method used in the video will not reveal this problem.  It will also register twice the resistance for a given temperature.

If the video was showing how to test a sensor that was from a later K1100, then they are using the correct technique.

when I ran the bike, the temp light came on before the fan, as the fan was broke. So the sender works?

Hmmm...
Just took it for a test ride. Goes like a bag of nails. Iím guessing injectors. It starts(eventually) but the choke need to stay on for ages, then it sort of kicks into life. Low revs are terrible and when you give it some throttle, it almost dies, then picks up at around 400Ē revs. Iím guessing injectors. What do you think?

Looking back, it appears that this is the first time you've tried to ride it.  If so, and the bike has been sitting for an extended time with fuel in it, there is a good chance that the injectors are varnished up pretty badly.

Get some injector cleaner(Chevron Techron is very good) and put it in the tank, start up the engine and let it run until it warms up and shut it off.  Let it sit for a day and repeat.  Do this a couple times until the throttle responds properly.  Once it is running fairly well, take it out for a short ride.  The injectors will slowly clean themselves out.

An alternative is to remove the injectors and clean them yourself.  There are lots of videos on YouTube that show how to do it. 

If you don't want to be bothered with doing it yourself, you can take them along with about 60-70 Pounds to an injector cleaning service who will flush them out and maybe give you a report on how they flow.

Hi. Yes, I only rode it around the block. Itís a pain to start, needs full choke even when warm, then seems to kick in, so choke goes off. Riding it, it was very sluggish at low revs, then picks up when you give it a hand ful, but didnít recover very well from it. I too am thinking dirty fuel system. I am happy to strip it down, as itís the only way to learn. You guys on here are also a great help!

In addition to Mighty Gryphon's recommendation review the following. The tank interior replacement lines should be high-pressure submersible. Check to be certain fuel line clamps in the tank are tight and that the fuel filter is mounted with the outlet in the correct direction.

How does it run without the patched up z-tube? Any differently?
Hi, yes all the lines are tight, present and correct. Tbh, I didnít really notice any difference with the z tube repair, as itís still not quite right, thatís why I was thinking fuel system.

Hello.
I have the conversion on my k75c,it also came with the original seat and side panels.
 What should under the seat look like? I.e,where the computer sits,tool tray,e.t.c,as I have loads of 'bits'. I Put  a new battery in,which was a tight squeeze,put the clamp on,then,does the computer just sit on top?
It's in a 'two sided box' type holder,but is that it? I can understand that becuase the seat is now lower,that there is not so much room,but does it just sit there like that,or do I have it the wrong way round?
I honestly don't know.
 A picture or two would be most helpful of under the seat of both conversions,normal and low,if you please.
Thanks in advance.

My í85 k100 was very hard to start when the engine is cold, even when it is over 90F (30C?). I suspected a leak in the throttle bodies but couldnít find it the conventional ways. I recently took off the throttle bodies and found one of the rubber tubes had a split right on the edge of the clamp. Ran fine once hot. Iím hoping that the horsepower is closer to the í91 RS 4 valve once I get the three tight valves to spec. and synch the throttle bodies.

That is interesting. Whilst my bike was running,I sprayed my first carcass,the one at the front,with a fluid we have here called 'easy start'. The Rebs went right down,and I thought that the bike was going to stall.I havnt yet taken that black box type thing off of the carbs yet. Could it possibly be that,I'm wondering?

Hey Soggz, all of the above will help. Although I think the general consensus is, you will never be able to get a properly clean injector done with household methods (but they will definitely improve things). I had my K75 since August and I have done EVERYTHING on it myself with the help of this great place, even if the  go-to K bike specialist of the region resides not 15 kilometres from my house. There are a very few things, I will be tackling with the help of the pros, and one is a professional injector cleaning service, as they operate the injectors in a special rig opening and closing them in quick successions some 10.000 times whilst sitting in an ultrasonic bath, replace the screen, o-rings and give you a before and after chart, all worth the 30 or 40 quid they charge for that...

BMW's transmissions are known to be a bit clunky requiring a deliberate foot movement, but mostly on the Airheads and classic K's.  The later K1200's had smoother shifting transmissions. Excessive effort to shift gears is also an indicator that the clutch splines need attention.  Have you been into removing the transmission from the bell housing and inspecting the clutch yet?

Hi.  I, engine is still in frame. At the moment, I am concentrating on getting it running right,  it I will be paying attention to the splines once itís running better.
The rear wheel be coming out, as the valve is leaking air,so the splines will be looked at then. Once they are checked over and lubed and itís running better, I will take it out for a longer ride to see what else needs doing. I understand from other people too, that changing gear on these bikes are harder and more methododic.

For the clutch splines you don't have to remove the engine, it is like a car engine with separate parts bolted together. If you have the final drive, rear wheel, calipers, etc off you are halfway there for the clutch splines. If you do not plan on removing the clutch itself, it is a reasonably easy and straightforward thing to do. Also I would probably replace the gear and final drive oil and add some moly additive to the gear case, (that probably helped with my clunky gears although it is hard to say if it was that, as I was doing many other things at the same time). My ancient CB400N in a rather sorry state had buttery smooth gears, compared to that the K is a chore, but you'll get used to it. The gear indicator actually helps, as you'll learn to have the indication in your peripheral vision - if you've found yourself between gears, the indicator shows nothing, so you'll know to try a bit harder :))

Ok, thanks for the reply. Yes, I understand that it is just rear wheel and final drive,removal to line the splines. Hopefully, that will make the gear change a little easier. I have also gone out and bought more oil for the gear box and drive box?().

Find some Moybdenum disulfide powder, 1.5 micron on eBay.  I add a couple heaping teaspoons to the gearbox oil and a little to the final drive.  After a couple hundred miles to run it in the ease of shifting is noticeable.  My bricks shift almost as easily as I remember my Hondas shifted. 

Another thing I've learned is not to pull the clutch in all the way.  A light flick is all it needs.

I followed the Mighty G's advice and can attest to an improvement after adding moly powder to the gearbox. Note, it's nasty stuff and will stain just about anything not metal you let touch it. I used folded paper to guide the power into the opening.

Hi.
Report back from the injector cleaning place.
One never worked!
Now all working and within 2.5% of each other(?).
Iím guessing thatís good?
The guy said that they will be fine.New oil in gearbox and final drive,today, just waiting for injectors to arrive. New ĎOí rings and clips are here. Quick question...
Getting it all back together... pulling the injectors out took a fair bit of pulling.
Do I just put them back on the bar, connect them to the electrical plugs, then tighten up the 2 bar bolts and let the bolts do the work? Or do they have to be pressed in? Iím guessing the new runner o rings will make it difficult...

Put a little Vaseline on the o-rings and in the bore where the injector goes. 

As far as Nirvana,  Ilsa still needs a couple things; a lower fairing bracket needs to be installed, and I have a bad connector in the driving light wiring.  I also want to look at the monkey nutz and service all my starters. 

The good news is that I don't need any parts to do any of the jobs.

What makes the splines do this?
Is it from sitting long periods of time?
Where does the lube go?
Confession, I never looked at them on my first í85 K100RT and I sold it with 100k miles.
Valves were not checked until 80k miles and in spec.
Maybe I got a Wednesday motor?

It works better if you orient the part so the light reflects off the top of the splines.  The width of the flat surface at the top of the spline is the easiest way to gauge spine wear.

Having said that, your final drive doesn't look all that good either.  It looks worn enough that putting a good shaft on it will prematurely wear the shaft.

I'm guessing bad metallurgy or engineering. Seems that if the splines are not lubed about every 20-30k with a good moly based lube they can wear out.  Perhaps the one biggest K Achilles heel. Replacements are scarce and repair is expensive.

Idleness is not the cause.  When the shaft rotates, there is a very slight change in the relationship between the parts of the universal joint that results in a very small linear motion in the end of the shaft at the final drive.  The splines are designed to allow this linear motion, but they need to be lubricated with a lubricant capable of handling extremely high pressures.  Molybdenum is one of the best and is why brick owners use high moly content lube on their splines.  The normal lube interval roughly matches the tire life of the rear tire, so that is when conscientious owners lube their splines.

That you didn't lube your splines for 100,000 miles probably means the next owner of your old K100RT probably had a situation similar to what you're facing now.  I hate to say it, but karma comes to mind.  As far as valves, depending on how hard the bike was ridden, it isn't surprising that they didn't show a lot of wear.

Many vehicles have splined shafts that are not prone to failure.  BMW dropped the ball on this IMHO, a shame since the rest of the drivetrain seems to live forever.

If many miles means 3000Ė5000, that is doubtful. Not goosing the moto through its gears nor puttering along in a gear too low might extend the mileage but when the tips of those sawtooth-looking splines on the driveshaft break off, you won't be going anywhere. That happens suddenly. The final drive splines are worn, but are not in dire condition like the driveshaft. Ideally both would be replaced at the same time.

What year was the moto manufactured? The splines were hardened in the late '80s according to one history at at Anton Largiader' (http://www.largiader.com/)s website. Lack of proper lubrication, as Chaos has indicated, certainly contributes to their wear.

The linear motion is only an issue on drive shafts with a single u-joint.  Two properly phased u-joints will cancel out that motion, and CV joints inherently have no relative motion between the input and output. 

I suspect that someone at BMW said "hey, the motion is so slight it's nothing to worry about".  Especially, since adding another u-joint to the Monolever would add a lot of cost and unsprung weight to the rear wheel.  Finally, they couldn't hold off any longer and the Paralever was born.

*Gulp*....The bike is 1988. To be fair,I did buy this bike as a project, but I didnít intend to spend much more on it...however, looking at the state of the shaft, looks like I will have more time to save up for the parts, if If I can find any!
What an awful blow!
Still, I still have the trusty CX500.(that took me 2 years to get on the road. Still needs new rings).

Sorry Laitch, you are right obviously, I meant the driveshaft, it is just my full-on man flu, that makes my already questionable brain activities completely foggy :)

Soggz - You can have a look at the bay, as I said, but for some reason or other the 16T versions are VERY scarce. I was in your situation probably two-three months ago and it is a shock, when you realise, you do have to cough up for one of the most expensive parts :(

Anyway, being in the UK is your luck, as www.motobins.co.uk is selling replacement spline ends for around 65GBP and they also do a spline repair for UK RESIDENTS ONLY for around 100GBP. Have a look at their website as that will get you basically a 'new' driveshaft (the other end does not wear as much and if the U joint is fine, you should be fine for a good few thousand miles)

Although this sounds like snake oil I would be very interested to see, if it works. I wonder, how it is possible separate the socket from the shaft, if you have filled the gap with gluey material. Obviously very little spline material is left on the driveshaft, but if you can get it aligned correctly, and separate the parts afterwards, you would end up with a very precisely fitting pair of FD-DS. Also probably the new plastic-metal would break off in chunks after a short while damaging everything in it's path, mainly the final drive input seal, mating surfaces and so on

I am not sure if it does, both of the shafts are pretty much shot. Laitch recommended to replace mine immediately so I used it for an another 2-300 miles before I received the other shaft. Who knows, how long it would have lasted though the PO did not even know, the shaft needs maintenance so he was lucky and I bought a time bomb

Yep, just like you. I had also some alternator issues, some electronic glitches, cracked big elbow on the manifold, broken air collector box, crappy brakes and other bits and bobs I do not remember anymore. If I look back, since I have owned this bike, I have spent more time underneath it in oily overalls, than sitting on it but it is starting to shape now.

Someone else might chime in on this, but in my opinion you should probably worry about the driveshaft first as the final drive splines look to me in somewhat better shape. If you are like myself - riding the bike for 2-3-4000 miles a year and will probably sell the bike in the next five or so years you are - again in my opinion - not putting in enough miles to chew up a new driveshaft with the worn final drive shaft. Just make sure, you lube the hell out of that joint and do it regularly, even every year or so and you should be good...

Iíll let you know. I canít order the bit yet, as I havnt seen the state of the other end of it. I may try and get the shaft out this weekend. How do you do it? Does it just pull out?
Title: Re: This Is The EPIC Soggs 92K75 MAGA Thread
Post by: rbm on January 18, 2019, 07:04:03 AM
Yes, pull straight out.  Grab the exposed part of the drive shaft using a locking plier (vice-grip or similar) and with the help of a rubber mallet, strike the face of the plier.  It may take a couple strikes.  The shock will release the cir clip that secures the output shaft end of the drive shaft to the output shaft of the transmission. Most probably the splines on that end will be OK since the drive shaft is prevented from sliding by the cir clip.

You asked earlier where all the lubrication went on the final drive end of the drive shaft; why did it disappear.  Grease consists of active lubricating chemical (eg. molybdenum) suspended in a carrier like a wax or paste.  When put back into operation after lubricating, the rotation of the drive shaft causes the carrier to be thrown outwards due to pressure of the spline faces rubbing against each other and centripetal force of the rotation.  That action happens in the first few hundred kilometres of use.  With the paste goes the active lubricant. That means normal lubricants like lithium or graphite work NOT fair well in this application because of the way they work.  Molybdenum works by integrating and bonding with the metal.  The longer it remains on the part, the more of the moly adheres to the metal.  If you can prevent or slow down the displacement of the carrier, the greater chance you have of keeping the joint lubricated for the life of the moly.  Tricks used to accomplish this are to select a moly lube with a large concentration of lubricant, >60% is recommended by BMW and owners/mechanics.  Another trick is to mix the moly lube with Wurth SIG-3000 (a very heavy bodied sticky carrier) 50:50.  The SIG-3000 slows the carrier displacement for a very long time.  Another trick is to close off the open end of the drive shaft at the final drive end.  This retains the lubricant, preventing the carrier from migrating very far away from the splines.

If you want to understand why the splines wear the way that they do, read this article:  http://www.largiader.com/paralever/

Most probably the splines on that end will be OK since the drive shaft is prevented from sliding by the cir clip.


In addition to what Robert said, if you have trouble hitting the vice-grip, or if it slids off too readily, you can leverage the tool against the end of the swingarm, however you should use something in between the mating surface of the swing arm and the vice-grip, like a thin edged wood piece, otherwise the mating surface gets damaged very easily with the foreseeable effect, that causes. Also upon removal (and replacement) try to have the swingarm as straight as possible, otherwise you might be hitting the shaft multiple times just to realise, it has been freed long time ago and you are banging the bent u joint against the edge of the swing arm tunnel. Please do not ask me, how I know this :)) Upon replacement make the swingarm straight, u-joint straight, wiggle the shaft back to it's position and hit the face with a rubber mallet. It clips on easily, so no HE-man tactics are necessary...

I may have a go this week end. My injectors came back today, so I put them in. Still quite difficult to start!
I also notice the choke dosnt seem to work as it should. Iím wondering if itís somehow Ďstickingí.
Itís not the cable, as I can see that operating ok, but itís troublesome to start and keep running. Once it is running, it seems ok, but if you put the choke on, it seems to take a while for it to rev up to around 4/5k, then taking the choke off, it takes longer than normal to drop back down.
Something inside sticking, perhaps?

:D Mass airflow sensor, in order to access it you will have to remove some parts, like the tank, etc. Be careful when you try remove the top of the airbox, the big rubber elbow can go brittle and if you tug it hard enough it might crack. Mine was in tatters and I am not sure, if it was me being a dick or age deterioration, most probably both :)

There are two hose clamps on that elbow, no need to remove the one closer to the airbox, only the other one, so you can remove the elbow and airbox as one unit. The other hoseclamp is securing the mouth of the MAF to the airbox.

If cleaning the sensor try not to go all crazy on the thing, the sensor element is sensitive. I have cleaned mine with contact cleaner, even though carb cleaner would have been more thorough.

Hard starting could be many other things as well, I had air leaks, oxidised contacts, weak battery and a failing fuel pump combined with a clogged up fuel filter, since I have got ridden most of those problems, the bike is a joy to start (especially since having 10W40 semi-synth in the engine)

You'd probably really benefit by becoming familiar with the Bosch L-Jetronic FI system. It was very prevelant in the 1980's on several European marques.  This is a link to the manual:  http://jenniskens.livedsl.nl/technical/Tips/Files/Bosch_Technical_Instruction_L-Jetronic.pdf

When you can understand how the parts work and interoperate, then diagnosis is easier, and repair is easier as well.

Hi. Thanks for the advice.
My CX.
I bought it with just under 54,000 miles on it. It was sat in someone's garage since around 2004. I purchased it 4 years ago. It took me 2 years to strip and rebuild.(I had to save up for the parts,as I am a father of 3 with and self employed with a small gardening business,so,Unfortunatly,it dosnt pay much,however,I don't see it as work,becuase I enjoy it and it keeps me healthy,and that's important,right?). I bought it from the man that I bought the BMW from,as he owned both bikes,but due to unfortunate health issues,he was advised by his doctor not to ride motorbikes again.
So I bought the CX for £300,and then,3 years later,the BMW for £300. I understand that even if I have to spend a lot of money on it,I will eventually have an awesome bike! The engine seems ok.I spent around £900 on the CX so far,and about £250.00 on the BMW.

You want to use a light touch with a dowel to push the vane in the opening of the sensor assemblyósilver unitóto determine if it moves freely. This is among the last places to be checking for performance. Other tests on it can be done with the engine running, but your engine apparently doesn't do that very well.

You're out of your depth, in fact, many of us are out of our depths with that thing. rbm is right at home though. For him, it's probably as complicated as making tea. You, on the other hand, are right on the cusp of creating more difficulty for yourself.

I think you need to check the basics first. Are the valves set correctly; do the cylinders have sufficient compression?

You want to use a light touch with a dowel to push the vane in the opening of the sensor assemblyósilver unitóto determine if it moves freely. This is among the last places to be checking for performance. Other tests on it can be done with the engine running, but your engine yapparently doesn't do that very well.

You're out of your depth, in fact, many of us are out of our depths with that thing. rbm is right at home though. For him, it's probably as complicated as making tea. You, on the other hand, are right on the cusp of creating more difficulty for yourself.

I think you need to check the basics first. Are the valves set correctly; do the cylinders have sufficient compression?
yes, it moves freely. I know you can improve the bikes performance if you take the angled black lid off and move the toothed cog 5 teeth, clockwise, apparently.

+1 on what Laitch has said.  The MAF is pretty delicate and has a very precise resistance element in it.  Beyond making sure the door inside the throat moves freely and the connector is clean there isn't anything in there that I would want to mess with. 

In the throat there is a small wire thingy.  DON"T TOUCH IT!!!  It's the air temperature sensor and is critical to having the correct mixture.

Concentrate on getting the valves checked, doing a compression test, getting proper fuel delivery, and cleaning all the electrical connections.  As long as the door moves freely the chances are excellent that the MAF is good. 

If the bike has been sitting for a long time I wouldn't be surprised that the rings are stuck and limiting compression.  They will need to be freed up.  I would suggest putting a couple cc's of a solvent like Seafoam in the cylinders and turning the engine over to work it around the pistons.  Do that a couple times and let the engine sit to allow the solvent to soak on the rings.

If you can get it in England, I would recommend using Marvel Mystery Oil as the solvent to free up the rings.  The stuff really works, and cured an oil consumption problem in my K100RS.  A half quart in the engine oil, a couple cc's in the cylinders and the balance in the fuel tank.  Crank the engine over with the plugs out and let it sit for a few days.  Then run it a bit each day for a week or so, and then take some rides.  Depending on how bad the rings are it may take a few miles to see real results.  On my bike it took about 2-300 miles to completely free up the oil control rings.

If you start fecking with the insides of the MAF you will not get any additional help with running problems from most of us here.  You will be creating problems we can't fix.  That cog moving only works(?) in Oklahoma.

Don't lubricate the door.  The lube will dry out and definitely make it's operation sticky.

Yes, I understand. Basically, I just pushed it with my finger. Seems ok and moves.And the cog moving thing, donít worry, Iím not gonna touch it! Far to complicated!Anyway, borrowed a compression Guate and the reading goes as this. No 1 = 160psi, No 2 = 155 or there abouts psi and no.3 160psi.
I tried them all again, but the battery was getting flat, so they all read a bit lower. And we donít have sea foam in England.

I don't think you can align a single U-joint on a monolever drive so that it is "in phase ".  It would raise the question "In phase with what?".  The sliding splines on the final drive is what absorbs the non-linear rotational velocity imparted to the drive shaft by the Ujoint.

It is necessary and recommended to phase U-joints in a K100-16V / K1100 which uses a paralever drive to ensure the constant velocity at the input driven end exactly transfers to the output drive end.  See this excellent video for more information:  https://www.facebook.com/ScottTuningFork/videos/831883586937318/?t=159

Your compression is good!

Regarding u-joint orientation.  By installing the drive shaft with the u-joint caps in the shaft vertical, the weight that causes the joint to droop is minimized.  I inadvertently discovered this a whille back when doing spline lubes and the shaft on my yellow bike kept drooping when I tried to install it. I shall remember this when I come to put mine back in.

Thank you, nurse. That is clarifying. I haven't had that difficulty yet. I only have one moto so the opportunity for drooping-shaft syndrome has only presented itself a couple of times but wasn't encountered. Maybe light gravity was ruling on those days.

Soggz, don't take it personal, I have been told not to do things many-many times and I did them anyway. Sometimes it turned out to be OK, other times I ruined the whole thing and had to start anew. With the MAF there is a special MAF cleaner, you can get, and you can hose down the inside, as it is a mild abrasive, that would not damage the sensitive parts. Otherwise do, what I did, use contact cleaner sparingly, do not, at any circumstance touch the temp sensor. Some remove the black plastic cover to clean the insides of the MAF sensor, I am not sure it necessary, unless you know, something is not right there.

Oh BTW, check for air leaks. They can, as with carbed bikes upset the right fuel-air balance and the computer might try to balance for that, or you might run too lean, etc. Use carb cleaner with a long straw and direct the spray to specific parts - throttle body rubbers above and below the bodies, little vacuum caps, vacuum hose to pressure regulator, injectors, the z shaped hose, you have repaired even that big elbow going from the air box to the collector

Iíve been reading up about it. Is this the sensor which is suspended by wires which heat up electronically, thus knowing when the bike is in cold start mode? Then as the air flows past, it cools, thus letting the computer know that the bike is warming up, so it automatically leans back the mixture for injection flow? And yes, I know not to touch it with bare fingers, but apparently, it can attract dirt and oil over time(a long time), which in itself will give false readings. Therefore, can it be lightly cleaned with a cotton bud (q-tip) and a solvent with very light pressure?

The doohickey(technical term) in the MAF throat is not there to tell if the engine is warmed up.  Rather, it measures AIR temperature very precisely so as to determine it's density/mass.  Air is much denser at colder temperatures than hotter temperatures.  It makes it possible to more accurately calculate the amount of fuel necessary to be injected.

Engine temperature is measured by the water temperature sensor in the cooling passage behind the radiator. 

It appears you need to go back and review the Jetronic Manual.

Going to check the valves in the next couple of days when I have time.
The revs on it sound ' intermittant'.
Choke only seems to work when it's warmed up a bit too. On start up,throttle needs to be wound up and down a lot,and choke dosnt really work for a while,until about 5 mins in,then goes up to 4 k on full,2k on half.Take it off,and bike stalls. What does this sound like?
Thanks.

Ok,managed to start it up today.Before I did that...
Checked the spark,nice and fat and blue.
Compression readings good. But still running rough.
Sprayed contact cleaner at no.3 carcuss,and it stalled.

Well, most likely you have a massive air leak on one of the cylinders,  most likely the one, that stalled after hosing down with contact cleaner.  Use a straw and localised puffs of spray to determine,  where is the leak.

Btw an engine lugging, needing a lot of choke and thumping sound like only two cylinders working

Also if you have that sorted,  see Robert's excellent write-up on the temp sensor resistance http://www.motobrick.com/index.php/topic,11299.0.html

Lets's briefly review where we are right now.  The injectors are clean and the MAF appears to be working properly.  there is good spark.  Something is not right about the #3 air inlet and the engine still runs like crap.

This thread is now one of the longest in the history of Motobrick.  To go back and see what all has been done and seen so far is rather intimidating.  Perhaps as a public service you could list all the stuff you have checked and/or replaced so far.  Things like the fuel pump, fuel filter, fuel lines, fuel pressure regulator.  Etc.

One thing I wonder about is the plug wires, specifically for the #2 and #3 cylinders.  When they are reversed the engine will start and run, but like crap.  This is something that has happened in the past on several other bikes.  It happens because the #3 lead is longer than the #2 so it can be folded back.  A new owner sees this and gets the wires reversed and the bike runs like shit.  This may be your problem.

Unfortunatly,the leads are in the right place. The longest lead is on no.3,shortest,no 2,and middle length lead,no 1, but yes, I can see how this would confuse some people. The pump is new,as is the strainer on it,as are the inner tank pipes with no leaks.
The injectors have been sent off and cleaned and are all within 2.3%of each other on the flow rate chart. The pump pumps as it should, as I took the pipe off of the fuel bar and fired it into a can.
The rubber pump holder is new, too,so no contamination. The Sparks are blue and fat,
Havnt changed the regulator as I'm guessing it's working,as fuel is being fired out pretty well. The plugs are new,the crank breather z pipe appears not to leak and the MAF seems ok.Its a pig to start,the choke dosnt really work until the bikes warm,then it goes to 2000 reeves,half open,4000 revs fully open. I'm using new clean fuel.I can only guess an air leak,not checked the valves yet.

Read rbm's and Gryph's then, and ignore this one.

My understanding was that you checked each of the throttle body manifolds for leaks using carb cleaner or something similarly volatile while the engine was running. Has that been done? If not, that should be next.

The choke is actually a throttle speed actuator. It doesn't enrich the fuel mixture like the choke on a CBX. Check its linkage down at the throttle bodies. Have you inspected the throttle linkage to determine if it is obstructed?

The valve clearances should be checked, too. Their status will give a better idea of the engine's ability for throttle body balancing.

Did you inspect the throttle body manifolds for leaks? Did you remove them and look for separation and decay of the rubber?

We haven't needed to delve into the intricacies of fuel injection yet. We're still at basic fuel, air and spark mechanics. The injection system on these motos usually is reliable. Your moto has been neglected; cleaning and inspecting is the largest task. Maybe there is a fault in the injection control system but bringing the rest of the engine's systems to good condition will make that diagnosis easier.

The fuel pressure regulator's vacuum hose should be detached and checked for fuel intrusion.

+1 with vacuum hose
Your bike stalls when contact sprayed to cylinder three intake.

A quick test:
Remove vacuum hose from front of intake and plug ends. If now unaffected by contact spray your vacuum hose is leaking.
If there are signs of fuel in the vacuum hose, the regulator is leaking too.
By the way I'll try your method of diagonal drive shaft insertion, sounds good, a little kinky actually.

Sprayed contact cleaner at no.3 carcuss,and it stalled.

What kind of contact cleaner did you use?  Was it ELECTRICAL contact cleaner?  That stuff has NON-FLAMMABLE solvents so it can be used on live circuits.  If that is what you used, I am not surprised that the engine died.

What you need to use is Carburetor cleaner or ether starting spray.  It seems to me that it's pretty obvious you have a vacuum leak somewhere.  The confusing results with the engine dying instead of the usual running smoother is probably the result of using an incorrect material for the spray.  The most important thing to do now is to very carefully inspect the parts of the #3 air intake both above and below the throttle body.  If it was my bike I would do that BEFORE I did the valves.  That vacuum leak is the most important thing you need to fix.

Post by: The Mighty Gryphon on January 21, 2019, 09:53:27 PM
One of the shortcomings of the Jetronic engine management system is that there is a lot of distance and parts where a leak can occur between the MAF and the intake valves in the cylinder head.  All that stuff needs to be in good condition and assembled correctly or the engine will not run properly because it doesn't get a correct fuel/air mixture. 

You have a bike with a vacuum leak that has upset the air/fuel mixture.  To add insult to injury, it's quite possible the the previous owner has screwed up some of the throttle body settings to compensate.  The good  news is that the basic engine is mechanically sound so no heavy disassembly is needed.  If you work with us, you have an excellent chance of getting your bike running like it should.

Good plan.  Use a straw to localise the spray, no point in hosing the area down,  also have a fire extinguisher handy,  unless you want to risk to burn the bike and the garage down.  This is a real possibility,  just check other threads on this theme.

Pressure regulator wise -  having a good stream of fuel at the fuel rail. is. not telling you much about the regulator itself,  check if you have a steady stream back to the tank.  Also to assess it's correct operation,  you need to measure the fuel pressure and it should read 2.5Bars, if I remember correctly

I had (actually still have every now and then) a bad or loose connection on one of the injector wires in the harness.  When it went bad it would cause the engine to run on three cylinders similar to yours running on two.  A little wiggling on the wiring would make it kick back into life again.  It sill does it now and then and I have now got the wiggle down to a fine art, I can lean down while still on the gas and give the offending cable a tweak and presto the cylinder comes back to life.


Maybe you should check the continuity of the wiring in your harness as well.

What they sent looks to be for assembly only and not continuous use. The moly grease for the splines needs to be extremely thick and remain so at higher temps (200F?) so that it won't sling off when spinning around. The thick grease base is a carrier for the molybdenum disulfide material.

I can't express enough how THICK the GD is at least at room temperature. That's what holds the MDS in place. GD is stiff like hard butter. It's like tar and sticks to everything it comes in contact with.

David, the stuff he has bought is most likely Castrol Optimol, which is highly recommended for spline lube jobs. The Staburags NBU30 is actually a grey paste, and if I am not mistaken Chris Harris uses ONLY that for the clutch splines as he is somehow skeptical about Honda Moly 60, or whatever it is called nowadays. I could not get Optimol, Honda Moly 60 or the Staburags, so I have sourced a large cartridge of Liqui Moly LM47 as that was the stuff recommended by Haynes, but certainly Soggz has bought the right stuff, at least according to BMW...

That lube should work for all splined shafts. Some experienced and credible classic K riders use it straight from the tube; others combine it 50/50 with the currently available Honda Moly. For more confidence you could combine it. I would not hesitate to use it alone but the 60 grams of Staburags NBU60 PTM I purchased years ago will outlive my use of it.

An amount that fits comfortably on a toothbrush is all that is needed for each shaft. Molybdenum bonds to metal. The shaft must be clean when this stuff is applied; otherwise, this molyóor any other choice of lubeówon't be bonding effectively during use. Excess lube applied will be spun off and wasted.

The drawback of BMW's monolever drive system is the lube on the final drive input shaft should be applied every 6000 miles or so because it eventually is scrubbed off by the continual forward/aft action the suspension transmits to the input shaft and driveshaft union. Lube on the transmission input spline ls more durable.

Yes, thatís what I thought. The in and out motion of the shaft tends to make it shift upwards and out of the splines.
I will cross that bridge when I come to it though, as I donít think the shaft will get done for a while, as my mate whoís gonna do it, informs me that he a bit busy. Hopefully, I may have the bike running properly by then.

Well, I did not even know, there is non expanding foam in existence... However I am not sure, how much the foam would tolerate heat and chemicals, probably silicone is a better idea, you do not need much either, just a plug....

I've used the white Optimol for twenty years tried the Honda stuff once.  I'm now using the Optimol silver (grey) at 160,000 K's. The shaft is showing wear but still has plenty of life left. It is more important to clean and change it  often. I used to do it every 20,000 K's now I'm going to do it every 15,000 K's.

from the internet:
"Cured One-Component foam typically withstands temperatures from -200 degrees F (-129 degrees C) to +200 degrees F (93 degrees C)."

Though this is a crazy idea, I think foam has merit. In its favor, it's light and shouldn't cause an imbalance.

amen brother Martin. In various car/ bike sites I've read argument after argument about oil brand and viscosity. By far, the most important thing is change interval. Same applies to the splines on our bikes.

Three things that will give your Brick long life. Correct maintenance, correct maintenance and correct maintenance. After 165,000 K's and 26 years I've used one set of fork seals about 19 years ago, since then I have packed under the dust caps with heavy silicone grease. I also pack the brake master cylinder dust boots with silicone grease and regularly change the fluid. I am currently running a Chinese master cylinder as an experiment but have cleaned and stored my still fine OEM one. Same with the fuel pump. I'm on my second fuel pump damper but still have my good OEM one my brick runs all year round regularly and has never run E10 fuel. Still on all OEM cables lubed regularly with PTFE lubricant never WD40  also grease pivots. Still running all OEM cooling system parts except the fan, I change the coolant at recommended intervals with the OEM coolant. I and on my second breather  but I still have my perfectly fine first one that I clean and wipe it with protectant. Correctly maintained Bricks are pretty bullet proof.
Regards Martin.

Lol. I am. Iíve just cleared out a space in my garage and put another bench up to put all the bits of the bike on, as itís starting to take up more room in pieces, rather than a whole bike!
I think I will be starting with the air and fuel system coming off to check out all the rubber boots and things. Can afford the cost to replace them yet, however, I may be able to fix them using various mastics and 60mm heat shrink and new clips. Iíve calculated all the rubber bits to come out at £250.00, which is too much of an outlay for me for this time of year.(gardener,winter,not much work at the moment).But I shall carry on doing the Ďfreeí stuff.

Oh, hm, yes... However it is us not him, who keep on diverging :)

On returning to the other issues, try to remove the fuel rail once again and see, if you have spray coming out of all the three injectors, whilst cranking the bike... Also do the starter fluid spray test and if in the slightest doubt, remove the throttle bodies and check for tears in the rubber above the throttle bodies and the manifolds beneath. The rubber interconnections are cheap enough, so I would replace them, if I were you, the manifolds are costlier, so you might want try your heat shrink method. Also make sure you have spark at every plug, probably cranking for a couple of revolutions. However you should not overdo it, otherwise you will permanently close the starting relay... What else, yeah, fuel pressure - if you can borrow the same gauge, you used for the compression test maybe? I am not sure, if that particular one is good for fluids too though...

Ok.
Had the throttle bodies off today to check all the air intakes and boots,etc.
Good news on them. All fine,no splits or cracks.
Throttle bodies were caked in crud,so they are all cleaned up now.
Will endeavour to put it all back together tommorow.
One thing I noticed...the two little rubber 'vacuum ' caps(?).One was split,so I'm guessing that would be drawing air in,maybe?
Pipes all look ok,but I will replace those while I'm at it.( non BMW parts though).
When I bolt the boots back onto the top of the engine...good idea to use a little liquid gasket?

I think the bushings below the throttle bodies seal to the cylinder head with o-rings.  I would suggest that you get some before you reassemble them.  BMW doesn't list those o-rings as a separate part, but if you take them to a bearing/seal shop, they should be able to match them up.

And yes, those vacuum caps are critical to a good running engine.  Get new ones.

Whilst having the throttle assembly on the bench,  you might want to check,  if the throttle linkage is unmolested,  eg silver screws still covered in blue paint.  Even if paint is still present,  I would check,  if the butterflies open at the very same time and by the same amount...  Saves you hassle down  the road,  when you'll get to sync the throttle bodies

Hi, I would just replace all three of them. It is a cheap part and takes the guessing out of the game, at least you will know, they are good and pliable for the years to come. Also get yourself some narrow hose clamps to tighten the stubs to the throttle bodies, rubber bushings to the throttle body and bushings to air collector box. You can get the BMW one use items, the fancy Suzuki stuff or just plain SS narrow clamps, which are a lot cheaper

bushings - 11611460755 around 4 quid each

How wet are the spark plugs, a faulty temperature sensor or temperature sensor connection can cause problems with flooding the engine. Remove the fuel pump fuse #6 marked Kraffstoppe and see if it will fire up. It should fire on the residual fuel left in the combustion chambers. You can also try to ram the fuse back in as it starts to die, but you will have to manipulate the throttle to keep it running.  There are procedures for testing the temperature sensor on this site.

I tAke that back it's unlikely the relay failed while you did your repairs.  But for me I have a spare bike so I just swap parts. Try to start it until it floods then disconnect the four pin fuel tank connector and see if you can get it running as the fuel runs out. Sounds odd but try it after exhausting all other options.

+1 I've had to do that on occasion with my K100 when I inadvertently open the throttle while cranking.  When they're cold, they are very easy to flood, and once the plugs get wet they really flood.

The plug under discussion connects wiring to the fuel level sender beneath the tank which, in turn, powers the fuel pump.  Lift the tank to see where it connects.  For the flooding remedy described by Gryph and Martin, it's simpler just to disconnect fuse#6 as Martin indicated.

Don't worry about the TPS mine hasn't been connected for years. I disconnected once I totally sorted out the infamous K75 backfire on overrun. It makes tootling around carparks and tight places a lot smother. Actually you have reminded me to reconnect it and just adjust it only works at full throttle. The only downside is if you don't close the throttle on overrun it can still give a slight backfire. Due to the fragile nature of the OEM 4 pin connector I prefer to leave it alone and remove the fuse.

+1 on what has been said about flooding the engine.  Try to clean the plugs,  put the battery on tender or hook it up to a car battery via a jump cable and crank it that way.  FI is sensitive to correct voltage and you can easily fry the starter relay if you keep at cranking the engine for prolonged periods. 

When I had trouble starting the engine with a semi depleted battery in -5C I have gotten to the point,  when the engine would have not started even connected to a car battery. Once the plugs were cleaned I could just about start the bike without choke,  and it was smoking like hell for a short while.  After all the residual fuel burned off,  bike run just as fine, as before...

Now that I've looked at the wiring diagram I think the problem is with your fan,  I think you worked on that. All those other things I said we're wild stabs in the dark,  it's about time I started to resist that urge and look logically.
yes, I put a new fan on. But I only plugged it back into the original 2 wires, as logically, thatís the only ones to plug them into.

greetings...

at this point he needs to make a single poast of a list of everything he has done to this point in a forrmat that makes sense at a glance and a photo expose so we are all reading and seeing the same thing...

i guarantee you that if i had the details and big picture at the same time i would have it running if runnable...

j o
Good Idea,here goes.
Ok.
Got this bike
Put in new tank pump and filter mesh and filter
Started the bike
Bike ran like sh&t
Fan never worked
Put on a new fan
Checked engine thermostat sensor
Bike ran like sh£t but fan came on when it got hot
Checked for air leaks
Air leaks
Fixed crankcase pipe
Better...
Bought new crankcase pipe and vacuum caps
Cleaned throttle bodyís
Checked compression, all up in the 140ís
Took care of leaks
Now bike wonít fire

Just out of interest...
When I had the air pod off of the top of the throttle bodies,I twist the throttle and the flaps in the bodies open nicely together, but when I flick the 'choke' lever on,none of them move. Should they at least open a bit? Or is my mind still in the world of carburettors..?
When I pull the choke lever on and off,the lever far right of the bodies move,but I don't see it move anything,and yes,the cable is connected. Is it all electronic? When I had them off,I watched the cable lever move up against a little device held in by a 10mm nut on the end at the back. A small 'plunger' device. This was operating with the lever going on and off. Is that the 'choke sensor',controlling the fuel?

No. The increased starting speed function is mechanical. There are gap settings involved. See illustrations and text in Chapter 32-14 of the BMW K75/K100 service manual (http://www.motobrick.com/index.php/topic,11014.0.html) downloadable from this site in the Service Manual section.

ok,so no, to you donít see anything g move?. So as you look down into them with the air pod off, and operate the choke lever. You should see something move. Is one or more of the flaps?

what you are seeing is the switch for the yellow "choke" indicator light in the instrument cluster.  There should be wires coming out of it, unless the P.O. cut them off.

Disconnect the fuel lines from the tank and the four pin.

Slowly walk away from the bike holding the tank (in case something is still connected) if your five paces away from the bike you can see if nothing is connected to the bike.

It would be good to clarify.
yes...  nothing is connected...

nothing to change it with. I did have the bike running after I put a new battery, fuel pump, filter, screen on, not long after I got it. Running rough with a terrible idle. Had the injectors cleaned, put a new crankcase tube on and vacuum pipe covers, plugs,fixed the leaks.
 Impressions good
Sparks good
Fuel getting through and setting the plugs.
Dried the plugs and put back in.
STILL wonít start...

How do you know your fan work is good

One of your tasks is the cause I think

Other than what I've mentioned, I'm out of ideas
becuase Iíve had it running since fitting and testing it. It was running for 10 or so mins, to let the fan come on, so I know the heat sensor works too, otherwise it wouldnít have come on.

There are some great suggestions here.  Gryphon is right,  the gear indicator's connector is exactly like the tank one,  so it is easy to mix up and that would explain your no crank situation.  Also do the easy stuff first,  dry the plugs and charge the battery,  a new battery does not mean a fully charged one.  If you still have the trouble persisting,  DO NOT disconnect the fuel pump by it's connector but removing the corresponding fuse.  If still no luck,  you can try everything else suggested.

Ok guys,had a spare half hour in the garage.
Here's where we're at...
First of all,I confess,I'm an idiot.
Bike cranks with the tank plug disconnect.
Ok.
Plugs have been out all night,put them back in.
Cranked bike,bike tried to start,or rather,coughed a bit.
Pulled the tps off while cranking,and it tried to start again,smelt fuel.
Took the plugs out and dried them off,then replaced them.
Cranked it over and it tried starting again,only this time it did for another 4 seconds,then stalled.
Again,stank of fuel.
Too much fuel?
Took plugs out and dried them with a blow torch,disconnected fuel tank pump.
Bike started easier,as plugs were hot, then died again,( I thought it may have been due to lack of fuel as pump disconnected ).
So I'm thinking...
Too much fuel?
Could it be the fuel pump thing on the back of the throttle bodies has given up?
Not sure how it works. I just know that the po had stored this bike away as a working bike,and I guess everything just sort of deteriorated on it over time. The pump in the tank was pretty mushy,could the little pump on the bodies be in a bad state too? Is it a mechanical thing that needs replacing time to time?

It runs,  even if it does for a short period,  that is the main thing. Running too rich could be I guess many things,  however what you think is a secondary fuel pump is the pressure regulator.  Read through the excellent pdf again that was posted here a while back and that explains the operation of the whole system ina great and understandable way.  Also try to think through,  what exactly has been done to the bike,  since it run,  if I remember correctly,  you had the MAF off,  hopefully the temp sensor was unmolested? Also whilst doing the compression test,  did you do any leak down tests too?  If so,  you could have oil in the cylinders too. Whilst cranking with pump connected look inside the tank,  if all is well,  eg pump buzzing and a steady stream of fuel is being pumped back.

Try to start the bike with no. 6 fuse removed and plug it back quickly,  once the bike started.  Try to run it for a bit,  probably revving it, and so on to see,  if the system clears...  Apart from that I'm clueless,  but others will have some better idea,  if still the same happens

I do not want to sound,  like a complete twat,  but be methodical and don't mess with random things at the same time,  otherwise you will never know,  what made matters better or much worse.  Try to. make  a list of things,  you have worked on,  so you can check for correct operation,  e.g your MAF might not be connected correctly,  the air bypass on the MAF has bren misadjusted,  your water temperature sensor -  although checked for fan operation,  you should also check for correct resistance at the computer,  etc.

First,  does fuel return to the tank,  its a two minute job,  you can see it dribbling from the top of the tank to the fuel level.

Sorry,  I should have said fuel pump relay.

The picture is labelled wrongly.

The top left is the fuel pump,  load shed in the middle, horn on the right.

Does your horn work? Does the light cut out while cranking?

Swap the horn and load shed, does the horn work? Does the light cut out while cranking?

I think your load shed is not working,  but clean the pins,  push them in and out five times and try again.

Push the fuel pump relay in and out five times, clean the pins. Try again... No go... Test the fuel pump relay.

Hello All.


Ahem.
I'll keep this short.
I have a k75c.It was sat for 12 years,in a garage,in the dry.
I bought it,it wouldn't run.
I've put in a new fuel pump
New filter and mesh
Had the injectors cleaned
New crankcase pipe and vacuum pipes caps
Cleaned the throttle bodies out
New CHARGED fully battery
Cleaned all connections
New fan,too...

Now.
I had it running briefly,even went for a short ride on it,but it was really rough.
Limped home on it,did a compression test,all good.serviced it with new oil,filter,plugs,air filter.
Still rough,won't even idle now.
Plugs are wet,dried them out,reinstalled.
Starts,but only for a few seconds,then stalls.Plugs are wet again...
I've been told by a very helpful person on here,to maybe change the horn relay out with the fuel injection relay,as they are the same(?), just to see if that helps,as I know the horn relay works.
I will try this tommorow,as the battery is now discharged with my attempts to try and start it.
Thank you.
Photos to follow... ...

It appears that you are dealing with a gross overfueling situation here. 

You have looked at almost everything on the engine with the exception of the engine control unit(ECU) and the signal to the injectors.  The fact that your engine is drowning in fuel indicates that the fuel pump is working.  If there is a problem with the fuel pump relay, it is that it is stuck ON and the pump is running all the time the ignition is on. 

Before you start trying to swap relays, open the tank, and while listening closely inside the tank, turn on the ignition.  There should be NO NOISE from the fuel pump.  With the transmission in neutral or while holding the clutch lever in, push the starter button briefly, just enough to bump the starter motor.  You should be able to hear the pump run for a second or so and then stop.  If this is the case, your fuel pump and relay are probably okay.  Don't mess with them anymore.

Next, make sure the headlight switch is turned on.  With the transmission in neutral, the clutch pulled in, and a fully charged battery, turn on the ignition and push the start button.  The headlight should go out while the starter motor is running.  If it doesn't, there is a problem with the load shed relay.  If it does go out, the relay is okay.  Don't fuck with it.

For now, these are the only tests you should be doing.  Focus on just these tests.  DO NOT BE DISTRACTED!
Hi.
Headlight goes off when cranked over with a fully charged battery. Iím pretty much guessing that the ecu in funked!
I found one on fleabay for £30.00, so I ordered it up.
Always a bit sceptical about 2nd hand electrical items, but if it runs with it, then great. I guess we will see. Should be here next week somewhen.




And thank you, again.

That seems like good coverage. The starter cable connection and its mounting bolts should be in good condition. Inspect them.

After that return to the Mighty Gryphon's Reply #6 and inform us of the results of the tests in that post he suggested you try.

Hi.
What makes an ECU fail?

Thanks.
Title: Re: This Is The EPIC Soggs 92K75 MAGA Thread
Post by: rbm on February 02, 2019, 05:53:34 AM
There's no one particular failure event that can take out an ECU; there are many possibilities.  It's a complex electronic device and many different factors can contribute to a failure.  Examples are over voltage (voltage spikes, static electricity) or over current (short circuits) conditions that destroy components on the circuit board, natural end-of-life failure of a device, over or under temperature conditions that exceed the manufacturer's recommendations, etc.  Electronics will either die very early (within the first few hours) or very late; lookup "electronics reliability curve" on the net.  If left alone, the ECU can live a very long failure free life spanning many decades.  If disturbed or subjected to those above factors, the ECU can fail catastrophically in an instant.

Hey soggzy

Have you got a mate that can help with mechanical stuff?

And maybe photos around the tank and that?

If so you need another workshop manual, your flying brick one is good but the relay picture isn't and it has no wiring diagrams. I like the Haynes '96 edition for the diagrams are in colour. Black and white wiring diagrams give me mental indigestion.

DO NOT READ THIS UNTIL YOU HAVE CHECKED AND CONFIRMED THAT THE STUFF IN THE PREVIOUS POST ARE WORKING PROPERLY!!!

It is possible that the injectors are open all the time.  They are powered by 9 volts from the ECU.  The switching for them is unusual in that the 9 volts is applied to them all the time the ignition is turned on, and they are actuated by the other terminal being grounded by the ECU. 

The way to check them is to pull off the injector connectors, turn on the ignition and check for 9 volts on one of the terminals.  Turn off the ignition, and check the resistance between the other terminal in that injector connector and ground.  If the resistance is low, there is a problem in the injector wiring or the injector control circuit in the ECU. 

Unplug the big connector on the ECU and check the resistance again, if the resistance to ground is still low you have a wire problem.  Check the injector cable for a spot with rubbed off insulation allowing the wire to short to ground.  If the resistance is high, the cable is okay. 

The next test is to put your meter on DC Volts and put the probes on the terminals of one of the injector connectors.  While the probes are connected have a helper turn on the ignition.  The voltage should be 0.0 volts or very close to it.  If it is 9v, the injectors will be open all the time and the engine will be flooded.  Your ECU is probably screwed up.

This all you need to do.  FOCUS!!!

Sorry Soggz, I feel your pain, but electricity is completely above my league. However I would think, if you have a spray from the injectors each revolution, the injector loop should be fine and you should look at the issues elsewhere. If you read through the Jetronic manual carefully, you can METHODICALLY follow the paths of various sensors, that could wreak havoc to the system, air or water temp sensors fooling the computer, etc. Also I have posted a 101 starting issues page a while ago, read through that too, as it has a wealth of information, that could direct you. Even though I am not your man, but most of the members here are well versed in the problems, these bikes could face... However nobody is standing next to the bike in question troubleshooting methodically, what could be wrong and it is up to you to read very carefully through all the great literature available here to sort out this nagging issue, you are facing

Ok. Had the tank off today. I was told on here by someone, canít remeber who, that when the fuel pump comes on, it pumps the fuel out of the tank, to the rail to each injector, then excess goes back up to the tank via the front pipe on the rail, closest to the front of the bike.(the one,ringed). Only, I gentle put a thin screwdriver up the Ďinletí, but it would only go in about an inch or so, then stopped as though it was a Ďdead endí, so to speak. Is that right? It seems to me that the fuel that passes the injectors just goes up the pipe to the tank, and then stops. Is that how the pressure for the injectors are formed?

It is difficult to see on your photo, I think you have connected the fuel hoses to the tank the wrong way around.

No - the front hose on the rail is not the return, it is the supply.

Swap the hoses on the tank,  you should then be able to run your finger along the hose from the rear barb of the tank to the front barb of the rail.

I think your bike will then run.

Also if your tank is off the bike,  attach a hose to the front barb,  you should then be able to blow air into the tank, if not then the valve in the tank is blocked, if so it is an easy matter to clean out.

yes. By hoses are the right way around, exactly like this, from the link you sent me (minus the manometer).The bike did run before. I could put a vid up with it running, but I donít know how.

Looking from the left side of the tank,  does the hose at the rear barb of the tank join with the front barb of the rail? That is the right hand barb on the tank with the left hand barb on the fuel rail.

The return hose has a 90 degree bend just before joining the tank at the front barb. Your photo shows a bend on the rear barb which makes me think you have the hoses at the tank the wrong way around.

Hers a photo of the inside of the tank. As you can clearly see, the front barn is naturally blanked off from the bmw factory.So no, you canít blow air into the tank, and itís NOT an outlet. Like I said...the bike DID run, but roughly.
Title: Re: This Is The EPIC Soggs 92K75 MAGA Thread
Post by: daveson on February 06, 2019, 05:59:30 AM
It looks like it is blocked.

If fuel can't return, and you say you can't blow air into the tank, it is blocked, therefore fuel is not returning to the tank. Therefore the pressure regulator can't work.

Therefore you have about 60 PSI instead of it being reduced to 30 by the regulator, causing overfueling.

I know this is hard to believe but fuel must return to the tank.

You need to fix this.

Thanks. Yes, these plugs are the same as the ones that came with the bike. They came with a standard service kit, plugs, filters, that sort of thing. In my CX,I have iridium plugs. They too have been great! Just wondering if they would be good in the K bike, if I swopped out the leads for resisterless ones, like on my Honda.

What do you think?

Electricity is not my forte so it would be better to ask somebody else. As far as I know, you have to have a resistor somewhere but I do not know, what is the difference of having it in the cable or in the plugs.

Iridium plugs are a waste of money in old bikes apparently, although this could spark yet another 'what kind of oil' war.

Electricity is not my forte so it would be better to ask somebody else. As far as I know, you have to have a resistor somewhere but I do not know, what is the difference of having it in the cable or in the plugs.

Iridium plugs are a waste of money in old bikes apparently, although this could spark yet another 'what kind of oil' war.

You got it going yay👍

Did you reconnect the hose to the valve or are you running a hose through the filler cap opening?

If you reconnected to the valve and it finally started and ran but stopped again the valve is probably blocked again. Clean it again. The whole fuel system probably wants a good clean.

Yes, I will find time to take the tank off, and internals out and go through it all again. I must say, it was still quite hard to start. Iím wondering about breaking the jb weld seal and unbolting it to take it out to clean. I suppose I could reseal it again, or look into why it may have been leaking in the first place. Not sure if it has blocked again, as I have put the filler cap back on, and the battery is now flat. ĎItís on charge, and on a tenderí (Johnny). Hopefully, it blocking itself, is the reason why it wonít start again. I am going to have to start at the beginning and be more methodical, I think.

Hey szabgab,  just as a side note I'm curious about your title, it looks like a shortening of your names with your family name first. I have a friend from Hungary and Im thinking her family name is the same as yours.


Dave that's right,  my name is Szabů Gabriel,  as we have our names the other way around and my scren name is just a short version out of laziness :)  Szabů is a very common Hungarian surname,  similar to what Smith is to the English

I'm guessing you got the spare tank with the bike and your problem may be why the previous owner got it.

You could possibly use the spare tank but it looks like the early version tank so is fixed differently at the back and the electrical plug is probably different.

After unblocking the return valve you finally had it idelling nicely, if it's rough now it needs cleaning again.

You can't clean it properly because you can't remove it. Try to flush it and clean it more,  it will be difficult because of your limited access. As a test you could bypass the valve temporarily with a hose through the filler opening, but you would want to be careful about that of course.

Iíll just break the jb weld seal and unscrew it. I can always filler it back in again after. I might try and see if I can find another tank too, as this ones not that great. Hard to come by now though.

both bikes are on 77,000miles. The cx is 4 years older, as I think itís a different set of clocks which were broke at 20,000 or something like that. The clocks that were on it said 53,000 I think, so they are pretty much the same mileage. The cx shaft is still like new! Not a mark on any of the lands of the splines, unlike the beemer ones which were like sharks teeth! They are defiantly poor or quality, which for bmw, is pretty shite! And they have the call to still call a mini, a mini! You ever owned a real mini?, I mean a original 1963 1000cc mini with the high beam light switch on the floor?

I have read,  and it seems so, that the pinion shaft is harder than the drive shaft. This is a good idea as the shaft is cheaper to repair or replace.

I had a Yamaha v star,  which apparently had the splines replaced. I saw another one where both parts needed replacing. In both cases under 100,000km.

Daveson, Every fall before I put the bike away I do the splines with Honda Moly 60.  It's not around anymore, but the new Honda stuff is supposed to have even more moly in it.  Really, any assembly lube that's really sticky and has 60% moly will do the trick.  The main thing is to do it every year, or every rear tire change, which ever comes first.

Hullo. The splines are greased on the rear. On the final drive, Honda sensibly put a grease nipple there. I just grease it when I remember. I think Iíve done it once, when I rebuilt it 3 years ago...the front, I greased when I put it back together. It simply dosnt seem to wear. Better metal.

Cx's and bricks,  both good bikes,  both undervalued, so you get good value for money if you get one. You've improved the look of yours heaps.

The grease nipple is a good idea but don't think it's suitable for a brick since the spline is outside the final drive casing,  which is easy to remove anyway.

Yes.
 I just put the new splines on it to see. Held the drive with one hand and twisted the shaft to feel for play.
 I noticed a tiny, tiny amount of play in it, but hardly anything. Probably good for quite a few thousand miles, I would have thought. Lubed every year, as it only takes an hour or so on a cold evening.

Moly Disulfide in Chinese translates to "slippery Rhino horn", it's great on splines and will do wonders for that animal attraction Bricks are so fondly known for. Nice job making your own lube, can't wait to hear the reports. ;)

So what was the problem at the end? Clogged return valve?
I think that was one of the biggest ones next to air leaks. Inside the throttle bodies were completely black with years of grime build up. It starts and runs(idles) at a higher rev than I would like, but Iím guessing that now everything is super clean, the high revs are probably been where itís been tuned dirty. I also cleaned the maf, so Iím guessing that itís giving a better Ďair passí reading(?).
I havnt balances the throttle bodies yet, so that should help things.

Today I learned the hard way not to poke one's phone into a nearly full tank to video the return line. The video is OK, the phone is soaked with petrol and the display became somewhat discoloured. Fortunately it is accident insured :)

The reason I have gone into such antics was to see why is there the loud hissing noise that annoyed me for a long time. There is no return line down to the fuel pump and the petrol from the solid pipe end is hitting first the 'burrito' and the wall of the tank. I was just wondering, if anybody cut that line shorter, as it is not connected to that collector thing (the burrito) it is facing sideways and there is no barb at the end? See the video, sorry for the shaky end, as that was the moment I have realised, the top of the phone is taking it's petrol bath :) https://youtu.be/UCG4aEAgHaI

There's a lot of weirdness in that tank.  Is the burrito that silver thing? What is it? Is it tapping against the tank making the noise?

Maybe divert the fuel away from that area by attaching a hose. Maybe throw the burrito away.

Installed the Reynolds Rack, purchased right here on MB shop-o-rama.
Take away: The rear bolts are a pain, as the spacing to install is very tight and mounting a Z-bracket means making custom length bolts. I only wanted 1 sidecase, so it was only a 2 day job. Super heavy duty once installed, and I would not hesitate to belt the baby seat carrier to it and run errands at highway speeds.

Seriously considering a smoke array for the horrible tailgater's here, 4 on each side would do. I also have a small metal tube to deploy a phosphorous flare spread that could cover about 2 lanes, not much, but attention getting. Has anyone done this mod without cutting the rear loop, or interfering with the rear gunner swivel?

In a word, Maintenance. 

My RT has over 92,000 miles on it.  The previous owner took good care of it, and I have as well.  Splines looked new when I got the bike, and they still do.

That's the word.  I've got 75K on my '93 K75S, purchased with about 40K on it.  The importance of this maintenance was unknown to me at the time, being an Airhead guy I was just concerned about clutch splines.  Fortunately the PO had it done at least once as documented in the Haynes manual he gave me and I do it every rear tire change using either Honda Moly 60 or Guard Dog.

Come on soggz,  your fuel return valve is choked with rust. Actually you have limited access to cleaning from inside too. This bike has incredible access for repairs and you can get your hand inside the tank. Maybe cut that jb weld off.

Do you have swap meets over there? There must be somewhere you can get parts. The bike wrecker near me can sell me any part for a brick,  new or used, except fuel tank caps are only available used from that shop.

lolBy what I mean today is that I tried to start it and actually start it and it sounded okay rievs were high, around 1,1000. I let it run for around 10 mins. Fan never came on. Changing the Ďchokeí setting from high to low, I noticed from choke start, to midway, not much change. Then from midway to full, 4000 revs, then back Down to halfway, 2000revs, then to closed,1,100 revs. But it didnít go straight to 1,100, it sort of slowly dropped down to it. Fan still never came on. Pulled the plugs. Sooty,apart from the tips. So too much fuel? Dodgy engine thermo/fan on sensor? I ordered a new one yesterday, to replace it with. See what that does. And no, tbh, no breakers around here and the parts are just stupidly overpriced! The cheapest thing on one of these bloody things, is the rider!

Yeah the return valve was blocked, causing overfueling, you half cleaned it, so it's half running now, so not surprising if it's still running rich.

 At the front of the return valve,  near the top you can feel an opening. You can scratch around there with an Allen key,  then try with something finer.  Try air pressure, maybe water pressure sprayer, clean it well.

You can probably even use a tank from a different bike,  I had a commodore external pump for one of my bikes. Another one had a falcon pump from the previous owner who had a fleet of falcons.

the "Fuel return valve" you may be referring to is called a "Fuel Pressure Regulator".  test it using a fuel pressure gauge.  you can't clean it by sticking anthing in it.  replace if bad.  (and if it "needed" cleaning, whatever crap was in it had to have gotten through the fuel filter in the tank and the crap would be in the injectors too.)

the "choke" does not enrich the mixture.  all it does is open the throttles to raise the idle.

Post by: The Mighty Gryphon on February 28, 2019, 10:41:10 AM
Soggz,  As a test, take the fuel return line off the spigot on the tank.  You might need to block the spigot off with a piece of hose and a plug to stop the fuel from running out.

Get a couple feet of fuel line, (it doesn't have to be the fancy stuff, even cheap PVC tubing will work) and add it to the return line.  Stick the end of the return line in the filler opening and try running the engine.  That will bypass the check valve in the return spigot and give you an indication if that is the problem.  If indeed the valve is the problem, the engine should run better with this setup.  That will tell you that the valve is the problem.  Re: the valve, I see they are $8.62 here in the U.S.

Marshall, early model tanks had a check valve in the return line spigot to prevent fuel from siphoning out of the tank when the fuel return line was disconnected.  I guess the internal plumbing of the tank was changed on later tanks so the check valve wasn't needed.

Funny, as I just confirmed the last 2 issues of BMW ON magazine had only a single, small picture of a non-white person in the magazines (p84, with the benevolent Caucasian standing over.)
Coincidence, MAGA, government cover-up, or more Ancient Astronaut misdirection? You make the call.

No, they don't, however when we were in New York and New Jersey for three weeks last year, everybody was extremely nice and helpful. I guess d*ckheads and nice people mix everywhere in the world. BTW that was also the time, I have seen a very nice greyish-bluish K75S near Perkins Memorial Tower and I decided to have a look at these and not the RT, and subsequently helped me to buy my turd coloured hobby-bike several weeks later :)

Hey, hi, The Mighty. Itís actually running!
I think you were spot on with the fuel return valve not working.
I managed to salvage one out of a spare K100 tank that I found and put that one in.(pic above of it working(amid all the pics of that bird that mods keep posting in my posts).
It runs, but when revved, the revs take a short time to return to normal.Not sure why, fine tuning, I imagine. Also, I think there is something wrong with the throttle bar, as when I rev the bike, then let go, the assembly dosnt seem to return to its original position, unless I press down on the little 8mm bolt, just inbetween the first and second throttle body. It seems to still run rich, so I turned the Allen key down 1 whole turn on the maf via the hole in the top of the air box. Now it dosnt seem to smoke as much.
Thanks for asking. You keeping well over there?

Post by: Soggz on March 08, 2019, 02:08:54 AM
Earlier on, I discussed the maf sensor. I bought some dedicated maf sensor cleaner from the inter web and sprayed it with that. I sprayed it over a piece of white paper to see how dirty it actually was.
The results are pretty good on that. The colour of the paper when dry showed lots of particles of crud, the sensor itself now has a shine to it. I replaced it into the bike and did a short test on it thus.
I turned the Allen screw right down in the corner of the air box. Bike wouldnít start.
I then turned it out a whole 5 turns and did the starter button test. Bike started, idle revs are around 1,050, start button pressed and engine revs neither dip nor fade, so air flow is correct.Took it for a very short blip up and down the road and the power is certainly there.
Gearchange is smooth and the new splines seem to be doing their job. Unfortunatly, I noticed that  one of my Ďnewí fork seals are leaking, but I will sort that out next week.and I still need to get a new indicator relay, a right indicator switch, as it snapped off and was only ever glued on, by the looks of it, finish the cowl, maybe get the wheels bead blasted as they are a little rough, and a new set of tyres, which if anyone has any recommendations, would be nice. Not silly money though. Anyone rate the shinko 705ís?
I have heard a bit about them for these sort of bikes.
Thanks for all your help, hopefully, with one thing or another, it should be on the road for summer!

Tacitly agree with the Shinko's. I put on a set last year (SR 712R and 712F) in stock sizes. Super value, and hold the road well after a couple hundred mile scrub in.

I had the CRAP scared out of me doing 55mph onto a 2" drop graded roadway with the asphalt lines being 1" apart and 1/2" raised across the entire lane. Front tracked to the lines and I lost nearly all control, leaning back and slowing to 40mph as a car tailgated. The rear wheel danced along picking it's own line, but staying +- 6" in line with the front. 3/4 mi of "this can't be real." Felt like endure riding as a kid.

thanks. I have shenko tyres on my cx, they are really good in various weathers, thatís why I am choosing to go with the shinko name. I had read that the 705 is a 20/80% tyre. I think it would be good for around where I am, as there a few gravel tracks around here to explore. Not Ďoff roadí as such, but Ďscenic short cutsí.

Fortunate luck at the local motorcycle jumble today.
Near the start of my MEGA thread, I needed a new indicator relay. New ones seem to be very expensive, also, plug leads are ridiculous money.
Still, I got 3 leads for £1.00 each, and a whole K100 relay box and loom for £15.00!
Luck favours the brave!
(And got some sweet bars for my cx,£5.00).

If you have checked for vacuum leaks on the throttle bodies and their bushings, then the next thing to check would be the valve clearances, especially the exhaust.

Good plan :) Also there is some conflicting info as to what is proper idle speed for a K75, some say it is 1000RPM or even lower, but 1200RPM seems to be the best, at least on my bike. 1000RPM is OK-ish, but higher RPM makes for a steadier idle, also bike picks up speed better, no hesitation, etc. At 8-900RPM my battery light starts to glow, so I have it set at 1200, and I am happy with that.... Maybe try this higher setting, and see what it does to your idle...

good idea, the idle is low, under 1000. May screw the idle bolt down a bit. I did read on here somewhere that the light switch for the Ďchokeí at the end of the fuel bar can stick and cause the throttle not to close down properly?

Ok. Replaced the splines on the prop shaft 1050 miles ago. They are now already worn!  It sure they were made of hardened Steel like the original set.

Send a picture to whoever you purchased the splines off, and see what they say.
Regards Martin.

If you replaced the spline collar without replacing the worn FD pinion you were asking for trouble.

Yes. I did earlier. Thing is, the replacement splines werenít made of hardened steel like originals are.In my opinion, they should have lasted longer regardless of the final drive spline condition.

Ok. Looking for a good final drive now, and do it all over again over the winter. I want to get this drive shaft issue sorted, as I want to do a fair few miles on the bike next year around Cornwall, as my disabled brother is moving there to be closer to his new born grandchildren. The bike is my transport of choice, as I need to keep the miles down on my work van.
The K75c is great to ride,so easy, too, but I canít have the drive components let me down. Iím a bit short of cash at the moment, as winter is looming up and my work as a gardener, will start to get scarce.

Guess you proved replacement spline collar made of recycled Datsun bumper poorly heat treated is a no go

Certainly looks that way! However, I did email the company (Motobins),where I  bought them from, and they said they have sold loads and have had no complaints. But I could have had a Ďbadí set, apparently. So they are sending me another one, free.
I also have managed to find and purchase another final drive in California on fleabay, which should be here near the end of this month. £249.00 with shipping, from a 35,000 mile bike.($303.00).
The new splines look a lighter colour than ones that I have seen on other shafts, so I am wondering if they are a softer metal that could be hardened with heat and quashing in oil.

The new set that I bought V a library pic of an original set. The original look much darker, ie denser, stronger material

The first set probably were parkerized or some such to prevent corrosion while the replacement wasn't.

I would contact Motobins for heat treat instructions.

Emailed Motobins. They say they donít know of any Ďhardeningí process involved with these.

The edge of a metal file will easily cut a notch in an unhardened part but not in a hardened part. Email them for instructions covering how the parts are welded together. Hardened and mild steel parts are welded together similarly as cast iron parts are welded. Temperature is raised to a level based on the metals involved, the parts are welded then cooled slowly. Specific welding rods or filler wire are used. Close finish fit of the driveshaft and pinion gear shaft is essential for reasonable lifespan of the parts.

What happened to the lubrication of the splined sleeve? Did much of it migrate onto the silicone plug?

Dunno about the migration. Iíve only just done the silicone plug, and put it back together.
