Hopefully i never have the same problem.I have an air-cooled bike. I found out that I need to be going at least 35mph in the summer to keep the engine from really heating up. Then again, I found this out when I tried to commute in Indiana in the summer -- 98 degrees on a slab of concrete, taking 45minutes to go 10 miles. The motor would try to sieze on me until I found a route that incorporated some freeway.
