My son road his 06 CRF450 for about 8 minutes with the hot start on. he tightened the clutch lever too tight and then used the hot start to start the bike. Well, the hot start lever didn't return and that left the hot start open during his 8 minute moto. He felt something was wrong, too hot so he got off and packed up and went home. He is in Florida and I'm on the West coast. Sent me a picof the lever as he found it today, fully pulled open. So, I am wondering what kind of damage could there be? It was a brand new top and bottom end, all new bearings from main to counter shaft. Fresh oil, and radiator fluid plus new over sized radiators.
