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?

Are you dealing with the new Spal fan? 

Did you run it before you put it on the bike?

Did you you change to the original connector? 

Did you make sure the polarity is correct so it wll run in the correct direction?

Great news! New fan fitted, antifreeze in, temp sender in,started bike....
Sat and waited
And waited
And waited...
Temp light never came on, fan did! Not for long, so I waited, then fan came on again, and again, not for long! So Iím guessing itís working how it should!
I wouldnít have been able to do it so quick if it wasnít for you guys on here. It spurred me on to get it done!
Thanks for being here for me!

It seems like it's working how it should.  :2thumbup:
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.

Thank you.
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?
Thank you,sir,for your reply.

I thought you were trying to spell crankcase. These engines don't have carbs; they have throttle carcasses.  :giggles

Hi Guys.
Took the injector rail off and pulled the injectors out. They were in there well! Whatís the best way to clean them? Would a sonic cleaner be any good? Or flush them through with carb cleaner, while intermittently connected them up to a 12v source?, or both?
