Radiator Fan not working - any help is appreciated

I can't hear my radiator fan kicking on and it's been that way for a few months now. It doesn't overheat, but I worry it may if I go on a long ride.

I checked the fuse and it's not that. Unless I checked the wrong fuse...

Any tips on troubleshooting this would be awesome. Thanks!

Maybe it's not getting hot enough to need to come on? Try grounding the fan temp sensor and see if the fan comes on.

Okay, I'll try that. I don't think anything' stuck in the fan. It doesn't even try to turn.

Is it a big deal if it doesn't come on at all? Most bikes don't even have radiators and coolant so I would think just the fact it has that should keep it cool enough to ride it as long as I like. Any thoughts?

The bikes that don't have radiators are designed to be air cooled, the 250 is not. If you are only doing short rides it may not be getting hot enough to need the fan.

Disconnect the radiator fan switch located on the clutch side of the radiator and using a jumper wire connect the two terminals. If the fan comes on then the switch is bad.

It takes a lot to get that damned fan to kick on. I think all the while I lived in California I had mine come on once. Then out here I had it kick on a couple of weeks ago when I hit some stop and go traffic (and it was 90+ degrees outside). The Too-Fiddies just don't produce a crazy amount of heat and very little airflow through the radiator is needed.

like mentioned above if you are constantly moving and getting alot of air across the radiator your fan probably doesn't need to be on , if your warning light isnt coming on then you are more than likely fine ..

Long rides are no problem. The airflow through the radiator keeps the fan off. It only normally kicks in at slow speeds in traffic in hot weather.

If your bike isn't overheating, the system's working as it should.
