put a new thermostat in my bike, and it still over heats, and even took it out completely just to eliminate the problem, and it still gets really hot, just wondering if anyone knows if this is a common problem, or anything i can do or justr some info about this problem, 1999 cbr 600 f4 thanks everyone

 

I had the same problem....bought a thermostat but never put it in...brought it to the shop instead. All they did was re-wire the fan or something and the problem was fixed, it was a cheap fix. The fan also was working fine (or so I thought) when I brought it in so I have no idea what the problem really was. Wish I could be of more help.

My bike would always overheat as soon as it was in traffic, now I am good to go; sure is a relief to have it fixed for this season.

 

ok so what i could possibly do is just wire my fan to a switch and turn it on whenever i want it on? do u or anyone think this may help the problem?

 

The problem is your fan. It doesn't matter what the thermostat is set to or even if it exists in traffic. If it doesn't work you will overheat.

You could wire it to a switch but for the life of me I don't understand why you would do that. It's a very simple circuit and is easy to troubleshoot and get to work correctly which is the best thing for the bike.

I'd start with making sure the fan spins freely (you can get your hand in there, even with plastics on) and the 10a fuse.

 

ok sound good, thank you, if anyone has any other ideas let me know thanks

 

Fix it the right way man. These are the only things that could be wrong with your fan, ordered from most likely on down.

1) Blown Fuse (Reason for that may vary)
2) Fan switch
3) Wiring / Grounding
4) Fan Motor

 

well i had the fan fixed, which wasnt a big deal, so now that thats fixed, it still seems to over heat? anyone have an idea what it could be? thanks

 

anyone got any ideas on what i could do to help this, it overheats more at lower speeds if that helps! it doesnt seem hot but the gauge says it is

 

Well the reason it over heats at low speeds is because there's no wind cooling it off. As far as a fix for the problem, i'm sorry i dunno

 

well i finanly took it apart and what i hope it wouldnt be it was, the water pump seized up, so anyone got one for sale?
