So, this it what happens, when piston is not changed in many hours time.
I'm guessing it is bikes 2nd piston if not 1st.
Probably original owner replaced it sometime, sold the bike and that's when the non mainteinance began.
Piston is polished, guessing to 15/100 of mm clearance, must've been a lot of skirt slapping to form those cracks.

Intentionally skipped the damage pics, as eventually that is what happens, when cylinder wall, rings and piston are warn, so rings expand into exhaust outlet and cut into cylinder wall.

Bad deal dude? How'd the cylinder make out?
