how do I know if a piston is standard or oversized ?
steve n on Jul 29, 2018
BEST ANSWER: All after market pistons will be stamped on the dome of the top of the piston. For instance, .020 would need an oversized piston. If the motor was ever taken apart and bored out, that piston will be marked and you will need an oversized piston from here on out. Hope this helps!
