i been trying to find the part number for the Temp sensor on my 3tj..its the wee one tells the rad fan to go on...can't see it on the online manuals...even phoned yamaha dealer today they wanted £50 odd for it..and wouldn'T GIVE ME THE PART NUMBER SEE IF I GET ONE ON EBAY ETC.....or see if there's another model that uses the same temp sensor...fzr600 yzf750 etc does anyone know????

I've had a look at the setup manuals for the 3TJ SP and the 600 Foxeye and they seem to be the same.
you can probably get a whole loom for £20

Have you got a picture of it as I have a couple of temp senders floating around but not sure if they are temp gauge or fan switch.
