Go up to the Profile tab, click on it, scroll down to the box labeled bike* then type into that box your bike's model and year of manufacture—as Olaf has already suggested—so readers will not need to backtrack to find out.

When you assert that you "have no temp light" how have you proved that? Have you tried this test?

If your bike's cooling components function correctly, the fan will start before the bike overheats, the temperature will stabilize then the fan will shut off. When the bike overheats, it is then that the warning light in the instrument cluster be will turned on.

Right now you can try to rotate the fan blades with a dowel or screwdriver to determine if the fan is seized or it rotates. That is a basic place to start. If it is seized, the fastest remedy is to replace it. Spal makes an excellent replacement fan that would need mount adjustments for installation. OEM-style replacements that bolt-in are available, and functioning used fans occasionally are found.

Thanks Laitch,

The bike also has a radiator cap that will blow (just like a car) before the engine overheats.

The fan spins free, i followed the process to override the fan temp. thing but nothing happened, i'm going to change the drive oils and sneak it out for a run see what happens, thanks again for your help.

The most effective way to know if the OEM fan is working is to jump 12V to its connector.  12V+ to the violet/yellow wire, ground to brown.

If that works then a fan not coming on problem is caused by something else being amiss.
