“The motor cycles overheats when the outside temp rises above 80 degrees. Once it overheats the bike starts to back fire and runs ruff. Dealer has no fix for it. Bike also makes a noise when it is in 5th gear. Once again dealer has no fix for the problem. I have talked with several dealers they know about the problems but will not do anything.”
