Default Re: What size are my pistons

I figure the general rule at .003" over normal bore size for wear (and that's accounting for normal piston clearance). Even .005" over normal is risky on whether the rings will seat well. Even honing will take out a little more. Sometimes it works and sometimes it doesn't. It cost more to bore the cylinders and purchase pistons but at least the chances are a way lot better that it will last a long time.
