I understand that 0.4mm is the standard gap for a piston rings for a p200 standard cylinder. My question is: does that gap need to change if I have an oversized cylinder? (In my case 2nd OS). Thanking you in advance. N

You'll get oversize rings with your oversize piston. Keep it the same .4mm gap and youre good to go! Positive
