Happy New Year!
I just cleaned up the pistons for my rebuild and found some pitting on one of them after all the carbon was removed.     This piston was at #1 cylinder. Is it unusable? I'm certain they are NPR 96mm pistons from a late-80's rebuild. I already bought new rings! Any opinions would be appreciated. |
