Well here is another puzzle that maybe some one can solve. bike is a 97 CBR 600 F3 mods: slip on exhaust
I was riding home from work and the bike started to over heat. I thought it was from the stop and go traffic but i never heard my fan come on. Even when it started overheating and spitting out fluid and i shut it off the fan still was not on? I chacked the fan fuse and it is fine. Is there a temp sensor that might be bad that tells the fan to come on ?

If anybody has had the same problem let me know.

 

directly connect your fan to a power source and see if it comes on. if it does then you know that the trigger sensor is bad.
did the temp guage read in the red when the fluid was boiling over? if not, but fluid was boiling over, then your system is not pressurized, possibly due to an old radiator cap or something.

Umm... what he said. Find out if the fan will come on by jumping power straight to it.
