My bike is overheating because for some reason my fan to my radiator will not turn on. I even idle'd the bike to 235 F and it did not turn on. I went on a ride and saw that it got up to 260 when I wasn't moving. Any ideas?

Check to see if you have a faulty cooling fan motor or even the fan control relay. Check connections also to the above mentioned items.

Would you happen to know where the relay is?

should be located on the left mid section, right above the coolant hose. You should see three relays, the one in the middle should be the fan control relay.

Do you know how to check it? sorry I'm not that electrically inclined. btw I checked and the fan is getting power but isn't moving. It is actually a little tough to spin with my hand. Seems like it rubs a little on the radiator, possibly

if your fan is getting power, then the problem is with your fan. I believe the fan should be able to freespin when there's no power, will check with my bike later on tonight if i remember.

Yeah, it seems a little difficult to spin and I hope that it just needs to be loosened up some or something like that so it has more clearance to the radiator, so I won't have to buy a new one.

Is there an easy way to do that? I mean without taking the upper off and the radiator off?

forgot to check my bike yesterday, think you can remove the mid fairings to reach the fan, you just need to loosen the bolts so that the fan isn't touching the radiator. Possibly temporarily shimming so you don't have to hold the fan away from the radiator.

to check to see if the fan is getting power, take a multimeter set to voltage and let the bike heat up to temp, if it starts reading around 12-14 volts when the fan should be on, you have a bad fan motor.

well if it's getting power, it's either touching the radiator (i had this problem) or the motor is dead. it also means the relay and fuse are fine.

yeah i switched the relay with another one and its fine. It seems difficult to spin the fan so I'm going to try to take it off and bang on the brackets some.

sorry it took so long to check, keep forgetting, been busy lately. My fan does spin freely (no effort) with the bike off so you probably wanna try free up your fan from the radiator

oil light comes on due to very low oil or low oil pressure.
