I think that I'm going to take another route with these barrels and pistons. I purchased another set of barrels and pistons (stock 83mm) awhile ago and I'm going to take them over to the machine shop this morning and have them measure everything up, let them clean up the barrels and install new standard rings. I had it in my head that I should use the original parts but in this case I'm just going to take this route unless the machine shops says there is a problem.
And I finally figured out what was going on here, one set of rings has an oil spring and the other oil ring isn't machined for a spring. Maybe this will all work fine, but being a completely novice engine builder I don't want to find out the hard way.
Thanks guys.
