I have a 2005 blaster I blew the top end put a new piston and got the cylinder bored .40 over. Rode it 3 times and was at the track Sunday and the bike cut off we got it home and took the top end off. The sparkplug was shut all the way and the piston scirt was broken into pieces. And I think it put a hole in the middle of the cases near the crank. What should I do.
