- Too hot a spark plug and/or running for too long at very high revs.
- Or possibly bad petrol, as detonation can cause piston problems. Was the
- hole burned, or had bits of metal flaked off the underside of the piston?
- The bits of metal probably went out the exhaust port after grinding around a
- bit. Pray they didn't mess up seals or bearings.
