Re: Piston ring question.... (chicchocrider)
Piston rings are matched to the piston diameter, which of course is matched to the bore diameter. If your installing oversize pistons then you need rings to match. OE size pistons require OE size rings.

Unless you bore the cylinders out to 81.5, use 81mm.
If you have a machine shop use an aggressive hone, measure ring gap and make adjustments as necessary.
If all of this sounds complicated, pay someone.

yes.
The oversize is for bottom end rebuilds where the bore is increased slightly (and to be used with the "rebuild" 81.25 pistons.
