Hi I bought a 400nc engine and wanted to check condition before use so took head off and noticed that both pistons looked very shiny where the inlet valve cut outs on the pistons are and slight damage to edge of piston at extreme outside of cutout looked like valves had contacted pistons but checked valves and they are straight and undamaged so a bit puzzled has anyone seen similar or have any idea why this has occurred please
