Boiling sound from radiator

Post by koolranch »

Looking for some advise. I ran my 220 over the weekend in some tight woods. When we took a break I could hear a boiling sound coming from the radiator. I did not see any leaking ect. All hoses where intact. Just wondering if this is normal or something larger to worry about. It stopped after a few minutes. I don't know the history of the bike to tell you if it's the original piston ect. It runs very good.

If it was tight and slow and you were doing a lot of clutch slipping etc the motor gets hot and that is a normal sound. Best to take a break now and then in those conditions. Check your coolant level and make sure its full. Also check your overflow tank and hoses.
