On my ringed engines I always take a piece of 400 wet or dry sandpaper, wet it with WD-40 and sand a light cross hatch pattern back into the cylinder.
Just a real light sanding to mostly break any glaze present.
The ring then re-seats itself to any position you install it in.
Been doing this for over 30 years on RC engines and even up to the cylinders on my 1996 Triumph 1200cc Daytona.
