Title: Not a cafe racer project K100
Post by: Skunky on August 25, 2017, 05:05:30 PM
Hi I recently stole a K100 ex police bike for a met £700. Up till now I have had newish
Bikes but this is my first build.

Thinking being ex Police for most of its 60k it would be well maintained I thought it was a great buy. The bike starts runs and drives and sounds OK if not a bit smokey ( seems to be running rich ) but plugs were nice and dry so no oil or water evidence just a little sooty. Clutch is a little stiff but it has stood for a while. I have in mind what I want to achieve and have made a mock up.






So started the strip down.......

I'm not one for giving a bike names but I have given this one many B######d F#####r piece of S##t and even the C word And at times all of them..

It would seem that although the Police mechanics maintain their fleet they do not use torque wrenches or anti seize. Bsds

The Exhaust had three stripped and crossed studs and no gaskets meaning it was corroded into place. One of the sockets snapped at the back and two studs had to be drilled out and re threaded but all done now

I have cut the frame and re- fitted and welded in the original rear section, minus any unwanted tabs etc. Ready for a seat build

Awsome providence,Skunky,welcome.
The smoke will be from the weed someone stuffed into the air box.Ha,the fuzz,aye!
The cuss word that works for my brick and Guzz,funnily enough,is:Honda.'Took a long time to find that out.
All the best.

Hi Dude

If it was Skunk in the air Box I would have smoked!.  But I imagine you're right about the air box. I think the Filter has been there for a few years smelt like a badgers box. Hopefully a new one will help the mixture and reduce the blackness.

There is a plug on top of the RH front of the air box, removing this allows you to access the mixture screw, with a 5 mm allen key. To adjust you can either use a exhaust gas analyser  or use a method called the lean drop method ( look up on this site). I bought a Gunson Digital Analyser years ago for between $300.00- $400.00 a lot cheaper in the US around $200.00. If you buy one follow the instructions to the letter and be patient, it has proved to be invaluable.

A little known feature on the 2v bikes ( not on 4v engines) is that with the bike idling at 1000rpm if you press the green stater button it will tell you whether the mixture is right. When you press the button if the mixture is right the revs should either stay the same or rise slightly. If the revs drop or rise significantly the mixture will require adjusting.
Regards Martin.

 On Monday my back had some sort of seizure reducing me to crawling around the house and not moving much. Not being good at inactivity I decided it would be the perfect time to make my seat. I have already made a seat pan using a rear from a RS as Sloping rear on the LT felt a bit clumsy.

(https://uploads.tapatalk-cdn.com/20170826/6cb6c716eebaa27508c82987c3997536.jpg)


The unit was cracked and therefore a reasonable price £15 .

So after cutting and painting I have built the new seat base.

(https://uploads.tapatalk-cdn.com/20170826/a6b7dfeb7c1a81ce4bf3907ae19507f1.jpg)

The lights and indicators are an led strip that will sit on the black line. (https://uploads.tapatalk-cdn.com/20170826/66dc2648de108159d802dc4cc28af548.jpg)

Anyway I had bought a used leather jacket  and turned this

(https://uploads.tapatalk-cdn.com/20170826/163dbdbe77183d6f78e4490d82ac558c.jpg)

Into this

(https://uploads.tapatalk-cdn.com/20170826/1ddee4adbfa26f86c0f22964cd9083b7.jpg)

I'm pleased with the outcome and know it will look better when stretched over the base rather than loose. Almost worth the back pain.

Greetings Beemer Lovers, Having mostly recovered from the back spasm incident I'm back on the project. The seat has been finished.


The stock front mudguards and fork brace trimmed down and repainted.




And work started on a new clock and warning light surround.

Good morning Brickers

This week has been an electrical and painting week. I was not happy with the paint on the rear tail piece so decided to reprint. I also rewired the tail lights shortened the cable and refitted the stock connector under the seat so that the seat can be removed. I then fitted a connector on the led light strip, wired in the resistors for the flasher circuit applied the decals and fitted the strip to the painted tail piece .

I also did more work on the fuel tank and the first four coats have been applied.

Overall there are about 5% or so that have fin damage and I decided to live with them for now and see how it shapes up in use. The fan is working well and worst case scenario is to buy another radiator .

Good Evening readers.

Due to health problems at home (not me) I have been unable to carry out any work since December. But I'm back on it in between carer duties so hopefully will make some progress. I may Put her back together and carry out further works as I go. Anyway Today I finished the re-wiring of the speedo to the BEP 3. Indicators, Lights , Speed, Warning panel all working OK except for a low fuel light which is ok as I have a fuel gauge on the speedo which is working off the fuel float. I will have to wait to check the RPM until the Engine is back together. Very pleased with the finish  :clap:.

Thanks DJ.

No issues at all really just as long as you know what you require. The only thing I can't use is the low fuel light. There is a circuit within the lunchbox which operates the low fuel lights using a transistor so there's not an output for it on the BEP. I tried to make use of the fuel sender to do the job but to no avail. However when the fuel sender gets low the fuel display starts to flash so you know its desperate.

Anyway spent a couple of hours polishing the tank paintwork. Still not satisfied .

Hi Skunky,  check out http://www.motobrick.com/index.php/topic,10224.0.html for the fix to getting the tach working with that gauge and the BEP.

Rbm - I had already read your topic on the tacho smoothing and have studied the circuit. Marulabs claim that the BEP 3.0 unit has solved the Tacho issue from the earlier models and the 3.0 has a suppressed RPM circuit between 0 - 9V
 
A quote from their installation manual states -
 
" - RPM and SPD is output as a square wave signal, which means that the rotary pulses from the crankshaft or the rear wheel respectively, are changed in a changing frequency of low and high pulses."

I'm hoping that they are right but if not you'll be hearing from me  :yes

You're right, but the problem is not with the BEP, it's with the gauge.  Read this thread to understand the fix I am suggesting:

EXHAUSTION!!

On my very first post I wrote....



So started the strip down.......

I'm not one for giving a bike names but I have given this one many B######d F#####r piece of S##t and even the C word And at times all of them..

It would seem that although the Police mechanics maintain their fleet they do not use torque wrenches or anti seize. Bsds

The Exhaust had three stripped and crossed studs and no gaskets meaning it was corroded into place. One of the sockets snapped at the back and two studs had to be drilled out and re threaded but all done now



What I never added was that one of the headers (number 2) was stuck in the engine block and during removal came of off the pipe, with the help of a little corrosion and the brutal efforts of an overzealous amateur mechanic. Anyway because I wanted to use the original round exhaust and the header pipes would not come out of the silencer I decided to try a high temperature chemical weld called JB weld High Heat and was able to carry out a repair losing about 14" off the pipe length.
I then shortened the silencer and painted the header pipes etc etc.

It seemed like a good idea at the time, until the refit anyway. Could I get the BSTRD to fit?  No!. I found that I had an alignment problem and no amount of prising heating of pipes etc could shift them. In the end I decided to get the heavy rubber hammer into use with the intention of knocking the F**K out of it until the header came free of the back box. Still wouldn't shift, but after an hour of ugly brute force and a vocabulary that made Goodfella's look like a kids movie, I noticed that I had managed to shift the offending header forward enough to force a fit.  :clap:

However, JB high heat weld is Tough as duck and has been smashed survived heat from a blowtorch and did not crack or break. Pretty impressive. We will see how it deals with Britains pot hole infested roads. Photo's to follow.

Don't hold your breath. Turns over OK. But would not start  :falldown:


So I need to go through everything and find out why. Checked the plugs and I'm getting a spark. seems to be a little fuel on the plugs but nor sure if there is enough or not. It could also be that there is not a full charge on the battery, I understand that they can be a little temperamental. So Overnight charge and give it another try in the morning. Failing that I will leave it until Wednesday and look at the fuelling.

Thanks Martin. I assume your talking about the fuel tank plug. I have already checked that. And cleaned all contacts. I didn't have time to delve too deeply as I was going away for a few days to celebrate my Dad's 84th birthday and visit my little Grand Monkey. Anyway fuel pump was working and I have fuel at the rail but not spitting out of the injectors. A quick check shows I have no voltages showing on the controller pins so that's where I will be going next. Probably due to the after market speedo installation. All the fuses are intact. I shall work through the wiring with Mr Haynes and sort it out tomorrow.

Evening campers - Spent some time on the Bitch today. Started with Basics, remade all ground connections, opened cleaned and sealed all connectors under the tank. Then started working though Crazy Frog troubleshooting guide and the wiring diagrams. Anyway I found that the Fuel injection relay wasn't activating when the ignition was on and the Start button was pressed which I discovered was caused by a poor connection on the Ignition control unit. Great I thought and put her together for another try. Still would not start.
Back to the drawing board .


I have a couple of questions


Does the fuel pump only run when you press the Start button or should it run when the ignition is on?


And the same question with regard to the FI relay?

The short answer is Yes, the FI relay closes and the pump runs only when you press the starter button, on your K100LT. An explanation of what happens is found in Vogel's troubleshooting document (http://hrsbstaff.ednet.ns.ca/bvogel/K100/download/bike-wont-start1.htm) if you scroll down through it about half way,

Thanks Laitch

I read Vogels step by step and have started working though it. Which is how I came by the FI relay not activating. I am at work for a couple of nights so won't be looking again until Wednesday or Thursday. I will be checking that the injectors are getting both positive and pulsing negative connections. And if not why not. I'm not sure how much of a fuel squirt I should see. I definitely have fuel pressure at the rail but there seems to be very little fuel on the plugs after trying to start. I would expect to see fuel escaping if I turn it over with a spark plug out. But I do not.

Hi Brickers


I Decided to get the wheels back on and get the bike off of the blocks and then tomorrow I will deal with the starting issue.

Don't hold your breath. Turns over OK. But would not start  :falldown:


So I need to go through everything and find out why. Checked the plugs and I'm getting a spark. seems to be a little fuel on the plugs but nor sure if there is enough or not. It could also be that there is not a full charge on the battery, I understand that they can be a little temperamental. So Overnight charge and give it another try in the morning. Failing that I will leave it until Wednesday and look at the fuelling.

Morning All

Yesterday was get the F##ker running day.

I armed myself with everything I needed to solve the starting issue. Multimeter, Electrical diagrams, De-oxit, Vogels non starting guide on my Laptop, Oil, Syringe, Patience and of course Cider.

Stage 1 - I opened cleaned and resealed all electrical sensors under the tank. Again!  :dunno

Stage 2 - Remove spark plugs, cleaned and checked the gaps. Then put a small squirt of oil in each cylinder to improve compression and smoke out the street  :nono. Put on the petrol tank and start..........................Still nothing  :dunno

Stage 3 - Start running through the Electrical system and Vogels check list. Injector and Temp sensor resistances were OK. Checked the FI relay had +12v and that +12v was reaching pin 9 on the ECU plug (and therefore the injectors) all good.
I then started on the negative pulsing from the by putting a 12v led between pin 9+ and pin 12 with the ecu plugged in and had no light up. I started to check the feed to the hall sensors and Airflow meter and when I was turning over the check to voltage I had a single pop ignition and a flash on the led. Bearing in mind the fuel tank was off at this time.
I refitted the tank and she started :clap: :clap: Smoke billowing down the street and very lumpy.
I let it run to burn off most of the oil and then removed and cleaned the plugs again. This time it started smooth as you like. :clap: :clap: :clap: :clap: :clap:
I would like to have found a definite fault but it appears the bike was just being reluctant.

Congrats on getting the F##ker running.  Seems yesterday was the worldwide "get the F##ker running" day because I helped a friend get his non-running K running.  It had been non-running since last year.  New plugs, fuel filter, and temp sensor cured the problems.

Thanks rbm, The information available on this forum and from the Guys that in habit it make the Job easy really. I come from an age where as kids we were always stripping and rebuilding our bikes and cars. Albeit they were a lot simpler. I despair at my children who would never change a tyre let alone a spark plug! :dunno.

Your conditioning circuit worked a treat by the way  :2thumbup:

Good Morning World.

Spent the last few days finishing off the Machine and then took it for its MOT. The garage where I go are very accommodating and looked her over before the test and advised me of the following.
Under new legislation the indicators on a motorcycle over 50cc need to be more than 240mm apart at the rear and more than 300mm apart at the front. When you consider that a 7 inch headlight is only 177mm wide that means that unless your Bike has long stalks it could fail an MOT. The tester told me that most bikes already fail this requirement!
Anyway I need to add extra indicators to the rear, he will let the front go through. New indicators ordered.

Also the rear brakes were binding. I had bought new pads and the inside pad seems to be dragging. When I looked closely it seems that the rear calliper does not sit centrally over the disc. There was not any shim fitted when I took the disc off for cleaning and I could not see any on my Haynes manual. I ended up sanding down the inside disc and it's moving freely now.

I need to play with the bike a bit. Its running a little lumpy and I'm getting popping and the occasional backfire. Wakes up the pedestrians  :hehehe. The bike starts on the button and idles ok. Does not need the choke either. I think I may need to look at the air mixture or possibly ignition timing. If I get no joy I will post a video.

Popping is most likely an exhaust leak, either at the head or the header to silencer connection.  Also, you need to completely close the throttle when decelerating.

Lumpy running may be varnished injectors.  A couple tanks of fuel with fuel system cleaner run through at high rpms can help this a lot.  Possibly one of the most enjoyable service procedures you can do to your bike.

Hi Gryph, I agree whole heartedly, I need to get some miles in and get the injectors cleaned out. I've added fuel/injector cleaner into the tank and will continue to do so for at least 200 miles. As for the popping and backfiring, i'm suspecting either air mix or temp sensor as it was running rich before work commenced. Again though as the bike hasn't run for 6 years I need to get everything settled down first. Every time I ride it gets a little better.

I should get the MOT done on Monday/Tuesday next week then I'm burning up miles.

My 16V K100RS had sticky injectors when I got it.  They weren't bad enough to justify the hassle and cost of removing and sending them out for cleaning so I ran cleaner in the tank for a thousand or so miles.  I still remember when they finally broke completely free, what a sweet feeling!  Like a supercharger kicking in.

Neither my front (either side of a 6.5" ShinYo headlight) or rear indicators (bolted to either side of the frame hoop) are 300mm apart, Triple S went through with no advisory's, MOT Testers discretion I believe.

He's letting the front go through which are 240mm. But he wasn't happy with the rear LED strip indicators when the brake lights were on as the yellow doesn't show clearly, so I'm putting a couple of additional ones on. TBH I had to agree with him. He also pointed out that the new headlight beam isn't the right shape. But as it's an e-marked light he's letting that through too. It just goes to show that even if you buy e-marked gear made for British roads they still might not be good enough.

Brotherhood of the Beemer hear my confession. Insanity! Distraction! or Just Early Stage dementia I am not sure......

Last Sunday I took off the rear tail piece,(which I had so lovingly created using a broken tail from an RS instead of the slightly clumsier tail from the LT), In order to fit some additional Indicators to satisfy the MOT gods. Fitted the indicators and later that evening went for a short run down a fast dual carriageway for a "check everything was OK" joy ride. Got back home minus the tail!!!!

Went back out and recovered it.

And this.......

Became this.........


* rearohdear.jpg (73.94 kB . 363x484 - viewed 671 times)

To say that I was pissed off would be an understatement. But it was me that put the tailpiece back on, and me that didn't put the screws back in. Oh and me that has to bear the bits falling off criticism and the "what else haven't you done up" Jibes from her in doors. 
I quickly knocked up an alternative tail from the LT one that I hag in the Garage (As you Do). But it doesn't fit the seat properly. I managed to get another rs tail unit from DJ Ewen which I will start work on this week. 



Apart from that the bike is finished and on the road and getting better every time I ride it. I will take the time to take some more photos etc and paste them up when I get time.

My BMW gets better and better I can see why you love them so much. I have created a hooligan with a sofa comfortable ride

Anyway Thanks to DJewen who sold me the tail from his bike so that I could replace the one that I smashed, I decided to change the design slightly to sink the light strip in flush.

Side Stand Mk3

When I first got the bike the side stand was snapped so I sourced and and purchased a replacement from fleabay. Cleaned and painted it looked ok. About the second or third use it snapped in the same place as the original!!!!!. After gnashing my teeth and cursing purfusily. I threw my hands in the air and said f##k it, I’ll use the main stand. Anyway come the real world of daily use, I soon realised what a pain it is on my slightly sloping driveway. Stop the bike pull it on the stand, open the garage, lift it off the stand drive in, lift in back. So the answer is get another side stand.
I searched for and acquired another stand this time from a K1100 as popular opinion and rumour say they are stronger.

Finished the last bits and pieces.

Made new brackets and fitted the new Tailpiece MK3 with the light strip sunk into the tail. Looks much better I think. I also used rubber well nuts and allen bolts for a better looking and stronger fit.

Fitted the replacement Side Stand. Or as DJewen called it the Suicide stand. What a mad idea a stand that springs back up and is impossible to put down while sitting on the bike. I find if you get off, put it down with your boot you can lower the bike onto it. Never seen one like this before though  :dunno.   

Finally Calibrated the speedo. I took the bike out with a GPS program on my mobile phone and it was within 2 MPH. GPS show 40 Speedo said 38 No changes required.  The cheapo Chinese speedo works great. The indicator lights are clear and bright and its accurate. I can say first impressions are that it was a bargain at £21.00 Sterling. I will update on its long term reliability.

Morning folks

Been a long time since I posted here. Bikes still going well but I have a list of things I need to attend to.

1)  Sort out the air balance. Still runs rich. The plugs need regular cleaning.

2)  The Fan is not coming on. Possibly its not getting hot enough but I suspect either the relay or sensor.

3)  Bloody Starter motor. Had to jump start it a few times. Just found out about the reverse sprag thing. But its working again at the moment.

4)  Fuel light, Not really important as I have a working gauge.

Still looks good though

Had some time yesterday.

1)  Sort out the air balance. Still runs rich. The plugs need regular cleaning.

Carried out a throttle body Balance using a set of vacuum gauges. And then tried the lean drop method to try to clean the CO2 mix. Seems to be running much smoother and cleaner. The adjusted is a fiddly little sucker to get to with my oversized mitts. It was really out a long way so I expect it to be better. I will run it for a while and chack for further soot.   

3)  Bloody Starter motor. Had to jump start it a few times. Just found out about the reverse sprag thing. But its working again at the moment.

Tried the reverse sprag cleaning thing a few times and it starts fine. I'm not actually sure if it isn't battery/alternator related as when it stopped working I lost the indicators lights and horn. I always leave my bikes on trickle chargers so it's always OK when I first start and leave but tends to fail later. Further investigation to follow.

4)  Fuel light, Not really important as I have a working gauge.

Euromotoelectrics sells a starter service kit that includes replacement brushes. Not much money and not a difficult job once you master pulling the starter motor. Worn starter motor brushes can lead to oddball electric issues, so this is totally worth doing.

As far as the sprag clutch, run the proper motor oil and that shouldn't be a problem.

Keep enjoying your K!

I. Already stripped the starter and found the brushes to be ok. However the copper contacts were really cruddy and scortched. 20 minutes with a wire brush did the job. I've had no starter trouble since 😁

Had a seal go on the front forks so stripped the wheel off and fitted new ones. Used a variation on Jonny’s plastic bag trick.

I’ve taken my K bike off the road to revisit areas that I want to improve. I’m going to upgrade the handlebar controls and switches but without losing any functionality. I will also take the opportunity to change the brake lines and change some of the dodgy connectors. (Starting with the 4 way to the fuel tank) replacing them with new waterproof connectors. Just about have everything I need so here goes.  [ Invalid Attachment ]

Completed some work over the last few days . Stripped down the controls brake and clutch levers and removed brake lines and fluid. I bought a slim choke control from a motoguzzi which will sit next to the new buttons and shortened the choke cable outer and make a new end to fit to the motoguzzi lever. I think it looks ok.

Hi Kids. 

As part of the ongoing handlebar upgrade I decided to fit bar end indicators. Mainly because I park my bikes in a garage next to the wall I decided to go for a cheaper unit and see how they work so I purchased the following units for what can only be described as peanuts.

 [ Invalid Attachment ]

The Indicators came and to my astonishment don't look too shabby. They have both white and yellow LED's in and are pretty bright. The only downfall is that when the white light is on the yellow indicator does not show up very well when the indicators are running. Other than turning the lights off when I indicate (which I will no longer be able to do when the handlebar switches are finished), the only other option is to have a circuit that turns the white light off when the turn signal is received, as seen on new cars with LED day running lights.
I decided to fall back on my very basic electonics training and build a circuit to do the job.
So using a 12v relay a capacitor and a diode I came up with a very basic circuit that as Boris say's "Gets it Done!"

I made a video of the result just follow the link.

Those do look decent, and congratulations on figuring out the wiring.

I wonder about the safety of white running lights on the handlebar ends, though. Mightn't that confuse the already dim-witted motorist? Will it pass inspection?

Technically on the British MOT you should not have a white light facing toward the rear so an over enthusiastic Tester could see it as a problem in which case I'll disconnect it. As for the dim-witted motorist anything that makes us more visible has to help.

Been busy with life for a few weeks but a stinking cold means I managed to spend time on the handle bar project over the weekend. Sitting down in the warm with a soldering iron and a pile of components is the best  cold treatment Ever.
I have wired the handle bar switches and connectors and the indicator wires are in position for the bar end units. Ready to start the refit.

Small side project. Replace the annoying and let’s face it, notoriously unreliable 4 way connector to the fuel tank and put it in a more accessible location so that I don’t have to remove the sides to get the tank off

Finished the handlebar upgrade all the switches are wired and working, with the wires running through the bars. I’ve also fitted new levers, master cylinder and brake hoses. The brake switch has been replaced with a pressure switch at the calliper. I have managed to retain all of the original functionality including the self cancelling feature.

A few pictures and a video below.

In Answer to Milq and another question asked by sr20clubbie

The switches are not Motogadget just ones from ebay. I wanted to reduce the size of the cables as I was running it through the handlebars. I also decided to only have switched negative reducing the chances of shorts in the switches and lowering the voltages so I used a 4 way relay board and switch the starter, high/low beam and cutout switch through that. I also fitted a changeover relay for the cutout as the cutout switch is momentary. I wanted to keep the BMW flasher unit as I like the auto cutout function as I'm lazy and have been known to leave my indicators on.

The Choke lever is from a Motoguzzi V11. i used all the existing BMW cables but had to make new cable end on the choke. It all works great.

Hi Skunky, what brake and clutch levers did you use?

sr20clubbie I used a set which are common on e-bay. However I had to make alterations to make them fit to the switches. I cut off the mirror fixings and repainted. I also did away with the brake light switch and replaced it with a pressure switch on the front callipers.

I was also not sure whether the brake master cylinder would be man enough but it’s better than the oem unit

Hey Skunky, thanks for that,I’ll have a look around is there a particular size reservoir that’s needed.

Thanks mate.

Hey Skunky, I actually meant what bore size. Most of the aftermarket ones I have seen are 14mm, I think I need a 19-20mm bore size (correct me if I’m wrong) did you get rid of the abs system?

Cheers Paul

I have rental bars on mine which have the smaller bore and I changed the rubber on the bar ends to make them fit. You can get indicators for 22mm bars. My bike did not have ABS fitted. But plenty of guys have removed theirs.

Due to the Pandemic I seem to have a lot more time on my hands lately, So after completing the Handlebar Switches I started looking at what else I can improve.

When I finished the bike in 2017 the mechanic at the MOT centre did not like the rear strip light because when the brake lights are on the integral indicators do not show up. So to make him happy (and keep me safer because he was right) I fitted a pair of mini indicators either side of the rear tail unit. Problem solved.

So why does it still piss me off!. Even after recently fitting bar end indicators I scoured flea bay until I found a light strip where the supplier claims the indicator sections are still visible when the brake light is on and ordered it.

Although slightly thicker meaning I had to make a subtle adjustment to the rear tail piece it actually works. I have taken photos of the old and new lights strips but because of the glare it doesn't look that different in the photos. So heres two pictures that look almost the same  :laughing4-giggles:

As an extension to the handlebar project. I decided to make switch ikon but the print sheet is so big I thought I would make my own tank badges to suit the Skunk theme.

Sorry, I haven't been on the site for a while.

Switches are switches and buttons are buttons. You can replace your existing buttons and switches with buttons which have the same function and therefore you only have to rewire them the same. I chose to put my wiring through the handlebars and decided to make all handlebar wiring negative switching only thereby reducing the number of wires needed to run through the bars. That required low input relay boards and an on/off latching relay for the kill switch. Its not the most difficult thing to do but you have to consider if it is worth it for you.
I love the look of new buttons but I have to admit that they are not as ergonomic as the original switches and did take some getting used to. To do it without relays you need latching buttons for the High/low beam and Kill switch. All the others can be non latching (Momentary) and then its just a case of replacing them wire for wire.

To draw a diagram as I have wired it would probably over complicate it for you. Get a multimeter and a circuit Diagram and have fun with it.

Cheers

Just another add on. I decided to try a keyless ignition system on the bike so thought I would get one of the Chinese PKE units that you just walk up to the bike and it turns the ignition on. Just to save the effort of messing around with keys. After a two and a half week wait the goods arrived. Unfortunately without the PKE ariel so basically I was ripped off  177381.
Anyway it cost peanuts to by so I shrugged my shoulders and fitted it anyway. Lo and behold it works  4265249878. Its programmable and as I don't like unnecessary noise when I set off for work at 5.00am (The bike is noisy enough  :laughing1:) I have programmed it for stealth mode.

Hi Motobrickers,

I can't believe its been four years since I finished my build, as you can see the bike is still going great and we (me and my beemer) took part in the Distinguished Gentleman's Rideout here in Derbyshire. I can't stress how much I love this bike and how much I learnt from this site, which I regularly pass on to other builders and owners on the Facebook K groups that I belong to.

These are really great bikes and I had the only BMW K out of 200 bikes. There were a few R100's but they are as common as muck these days.

Keep on Building and Keep on riding.

Agreed. Good design for the most part. I too was the only Bricker at our DGR. Oddly the only BMW out of 24.
