94' CBR F2. My radiator fan does not come on anymore. While driving, it stays cool but in stop and go traffic, that temp needle creeps up but never overheats. I checked the fuse and its ok. What else could be wrong? I was thinking faulty thermometer sensor, faulty fan switch...what else? Summer is coming up so I hope to get this resolved. Thanks guys for all your help.

 

have u put power to it to see if it comes on? Check the fan switch I had the same problem on my 01 gixxer.

 

jumper the fan-switch with the bike running and see if the fan kicks on. If so, faulty fan switch.

If the heat isn't getting that high, there's a chance that you're just not getting up to the point it feels it needs to kick on.
