3-Piece Oil Rings
I need someone to help my memory!
About 25 years ago, I did a top-end job on my 1978 Low Rider 1200. At the time, I also cleaned up my cylinder bores and fitted new period NOS H-D (Bohnalite) pistons. The piston rings that I used at the time were updated versions that included 3-piece oil rings instead of the original old-fashioned single-piece oil rings that came with the bike. The engine still runs great but, for the future, I may want to do a similar job and I can't remember what rings I used. It had to be a Harley-branded ring, I think.
Maybe it was that Eagle Iron line (from Taiwan) that H-D was selling in the 80's and early 90's. Or, maybe the rings H-D sold under the old part numbers had been shipped with the newer type rings. I think towards the latter part of the 1200cc piston engines that H-D had gone to the 3-piece design for them.
I can get properly sized rings 3-piece oil rings from Total Seal, maybe Hastings or maybe another aftermarket piston supplier but I'd like to go back with the H-D rings that I ordered before.
Anybody have information?

we have for at least as long as when you did yours always fit pistons with hastings rings in a moly top - cast iron second and the 3 piece stainless standard tension oil ring
that set up is the deal and we fit the pistons at .003 not what the book calls for as the book was written during leaded fuel days
total seal will not work air cooled street engine - I don't care what some drunk said in a Gin mill - they don't and never have
