I’m looking for rings for a couple of NOS oversize pistons (plus .015) for an HD25. I know I could have some made, but first was just wondering if anyone knew how I might look for an original OEM part number? (The Tenth Edition only lists oversize pistons & rings for the HD25 in Plus .020. The pistons I have are just stamped “.015”. Maybe these are orphans?)
Any advice appreciated! Have another question about re-boring but I’ll start another topic heading. Thanks in advance.
