Are you talking about the piston wrist pin retaining clip shown in the pic below ? that's SP # 09381-18002 .. it was used on bikes for over 40 years and is available everywhere. If not, please be more specific on what you are talking about. Do you have a manual?
Thanks for the response! Yes that's what I mean and yes I have a manual and they're referred to as piston snap rings but it doesn't make note of what size or part number they are and I have seen multiple styles and sizes of snap rings. I'm just trying to make sure I get the correct ones so they fit and seat correctly.
