[QUOTE="dirt bike dave, post: 120215, member: 18302"] I think you absolutely have to at least pull the cylinder off to take a look. My thoughts are that if it was still firing with the kill button pulled in and the ignition wire disconnected, something in the combustion chamber got really hot - hot enough to fire the fuel without any spark to the plug. Not good. Examine the piston very carefully for damage, and try to figure out what caused the bike to keep igniting. Some sort of metal burr in the combustion chamber or on the piston top could have got super-heated. Possibly jetted too lean. Good luck - IMO you might get lucky, but I'd plan on at least a new piston and rings. Cross your fingers and hope that your oil did its job and protected the main bearings. [/QUOTE]
