Any guess what caused this? I thought excessive piston to cylinder clearance causing the piston to "rock" and skirt damage, but noticed the piece gone seems to match the rod quite well. Maybe pure coincidence?
Rod bearing and wrist pin both tight. Motor was running before disassembly.
Piston skirt is scuffed bad both sides, I think dirt ingestion may have played a factor. Had only a metal screen air filter when I got it, and I figure it probably sucked a lot of dust.
