I had put a new wiseco piston in my bike and when i was running it and pulled the clutch in the bike died. Floated it and it did the same thing unless i cracked it to full. took the piston out and the thing is worn down 1 mm in the front and looks shot. the old piston i took out lookes perfect compared to this. Any reasons y thins happened? i broke it in correctly and the thing only has about 4 hours on it.
