so yesterday when i was riding to work i pulled the throttle back and it was miss firing and the engine light was flashing, i pulled up and then rear fan kick in. i let it cool for a bit then carried on and everything was fine! it happened on the way home again today! its almost like the fans not coming on when it should? like its coming on to late when the bikes already to hot, also normally when you turn the bike off the fan would always come on to cool the engine but now it doesn't. has anyone had an issue like this before??

have a quick look & see if there is any thing jammed in the fan itself,
make sure it spins freely by hand in case the bearings have failed ..mind your fingers

Cheers I’ll have a check. The fan does come in eventually. Just when the bikes to hot. I was thinking maybe a dodgy thermostat??

It should only come on when the engine is hot on a 2003-2007

yes i read this thread and followed the manual instructions to a tee! and all it does is just keep flashing 9 times, there was no 6 flashes then pause, just straight to flashing 9 times

im just going to try and get my hands on the proper cable and plug it in haha, im almost certain its the engine temp sensor but just wanna be 100% sure

it should work just as well with a paper clip or bit of wire, to short the two pins out
damn sight cheaper too

yeah i have no idea why the manual why didnt work?

ok! So! i finally managed to get the manual way to read the fault codes to work and it come up with the air intake temp sensor! ive just spent £140 on an engine temp sensor (which me and most people were almost certain it was the fault) to find out it was a £25 sensor hahaha still could be worse

£140? Wow is that how much they are?

Air temp sensor shouldn’t affect the engine temperature.
