Did you turn a ridge reamer in the cylinders before honing them before? It's normal for the rings to wear a ridge in there but it usually takes a while to get much wear. Boring the cylinders and putting in new pistons takes care of the ridge. If you get much more that .003" of wear out or round or .006" taper on the walls then boring is usually a good idea.

Soon as I get a bore gauge will see what that ridge measures, didn't use a ridge reamer before honing.
