I resently done some motor work and had the head off my 700. The fan seems to run longer now than it did before. It only runs for a long period of time when I'm riding down the road or trail and when I come to a stop it cools down and the fan turns off. It doesn't run hot about 193 to 196 its just the fan won't turn off while your riding it only turns off while I'm setting still. The radiator is clean and so is the radiator guard. Could I have and air pocket or bad radiator cap?

 

could be an air bubble
like a baby it needs to be burped.

 

How can I burp my baby LOL.

 

to get the air out ... just leave the cap off and run it until it's real hot ... you will have to stop the fan from running to get it hot enough ... then just keep adding coolant and make sure the over flow bottle is at the max line ... then just stick the cap on while it's running and restart the fan ... allow to cool ... as it cools the overflow tank may get lower and the air should be out of the system.


happy riding ... havn't been riding my self ... just flying our new RV6A!

 

I did pretty much what you just said earlier today and I think I got all the air out. I also added some water wetter and it seemed to help.

 

what is "water wetter?"

 

Its a product made by redline and you add it to your cooling system and it reduces heat.
