Cant keep a top end in my doo. Dealer tried to tank tune it today and said that it was still getting hot and sticking. They claim its either cooling or piston clearance. I doubt piston clearance. At first I thought it was fuel however they say its not. The pto cylinder sticks the most. very little to none on the mag cylinder. I need to know if there is something im missing? No signs of detonation in either cylinder. just skirt and cylinder damage in pto cylinder
