Racing a HS this past weekend when my bike locked up on the second lap. Tore it apart last night and the top of piston was broken on the edge and piece of the ring had also broken off and become wedged between the piston and the cylinder wall. Needless to say the cylinder wall has a groove and will have to be fix not to mention new piston.
Has anyone else heard of the stroke pistons doing this. The bike is a 2002 and I have only had it less then 7 months. The plug looked good so it wasn't running lean (actually its always ran a little rich). I am just not sure what would have cause this.
Please help
