it might be runnin to lean, or just a bad piston that blew up, ive seen skirts blow off before, but never that part, after it broke off it got stuck between the head and the piston and kept bouncing around leaving those huge marks, did you retrieve the piece that was in there? it may be in ur bottom end or ur pipe, if urlucky it just blew out but tahts a pretty big piece
