I am trying to find a first over piston and rings (56.75mm) for my 1984 XL 125. I didn't think it would be much of a problem, but it turns out that I haven't had any luck so far.
The part number for the piston is; 13102437000, and the rings are: 13021437000. Weisco doesn't sell them anymore as far as I could tell but on their web site they offer a ProX piston. My research on the ProX shows that it is compatible with a 1983 XL 125, but not a 1984. I am not sure as to why. I think in 1979 Honda went to a two piece head but I am not sure how the pistons have changed. I can find a NOS 1st over piston, but not rings. I haven't been able to find a matching piston and rings for 2nd, 3rd, or fourth over either, except from China or Thailand, and my previous experience with some of the Chinese and Thailand products have not been positive, and I would like to get the bike running before Easter as my daughter is coming home that weekend and wants to go riding. I have, however found 1st over rings with a 13021-383-620 part number. Does anyone know if these rings will work? They are the right size but for an earlier XL. Are the ring lands different between early and late XL pistons. Does anyone know a resource for these parts.

For some reason the rings didn't show up in my search, but maybe I should have searched by part number. Anyway the parts are on the way.
Yeah, I usually have the best luck using part numbers in ebay searches. Good luck with your project and I hope you and your daughter have some great rides. Must be lots of good off-road riding around Redding.
