Bad temperature sensor--fan sensor. It is what tells the fane to come on. Or you might check the connection to it--make sure it is connected.

Could be a thermostat also. You just have to diagnose the system to find out what it is. What speeds are you doing? If you are driving at 40 and above, the fan really should never come on. There would be enough air flow to cool the antifreeze.

:welcome: to the forum also. :bigthumbsup:

I'll throw another one at you just because it happened just like you describe but on a different bike. the area where the radiator cap seals was pitted and allowed coolant past there and into the overflow without much resistance. quick check of the cap rubber seal and the sealing surface underneath is in order. :bigthumbsup:

what was the result? I think my fan is not running too! When it got in the 80's last week my bike got fire hot! a pinging was developing in the bike too. When I got home. Oil flowed out my intake. I think it had been over heating.

The fan used to run when I hit the kill switch. Now nothing. And it's been nothing for a long time. I just ordered a new sensor ,but was wondering if it could be the thermostat. However I don't have any problems with over flowing.:dontknow:
