I've only just got my bike running and not too smoothly but I've not been getting the temperature gauge moving or fan kicking in. I've shorted the gauge and fan and both work. However i'm not getting a resistance across either temperature sensors. Does anyone know where I can get a replacement for both preferably not at £80 each. Or is there any alternative sensors that will do the same job. Any help welcome, thanks in advance.

So I found a sensor for the gauge and it shares the part number with the one off the gk76 but not sure if its correct. I fitted it but I'm still not getting readings that make sense. Here's a link to the part for anyone interested.

Sorry mate I meant to post but been busy.
It should be shared with a few models bandit is a probable one.
If you download the manual it will have ohm readings and temp tests for the part.
Ive just stuck a ohm meter across a bandit one and get no readings so I'm guessing you will have to put heat into it,
It will maybe not read under a certain temp.

Price is right anyhow...well done on posting this up.

My original gauge sensor gave no readings until my new one arrived (typical) and then both gave similar readings at room temperature(in my hand). I fitted the new one as I thought the original was temperamental. However the temperature gauge didn't move very far and yet the bike seemed to get very hot, to the point where my thermostat housing started leaking, it looked like the plastic had warped slightly breaking the seal. My bike isn't running properly and I believe a bit rich so potentially it's not as hot as I think but it felt hot stood next to it. I'll try and find the ohm readings and see if they correlate and then post my findings.

My fan has also never kicked in and I tried testing the switch in boiling water but I never got a reading, does anyone know at what temperature the switch activates?

I cannot help on that score but you will find a cheap infrared laser temp gun is invaluable for your diagnostics.

Poor running, temp not coming up and richness are prime examples of the orings in the carbs not sealing.
Changing the orings usualy sorts it.

The thing is I have changed all the o-rings and the main jet one twice as they tore the first time I put them in so I've put new ones in. I'm going to check the float heights next
