Yes, I saw that earlier when looking for new rings for my Action fours 836 pistons that use CB350 twin +1mm rings. Cheap sets of rings that were OK except the oil rings.
RC can use same as AF (I compared the pistons) but difficult to find today. Here sold out. http://bore-tech.com/product/350-piston-ring-set-65-mm

My NOS cast RC pistons have the old 3 piece oil rings from my AF pistons. I thought that old 3 piece will be better than a new 1 piece oil ring. Ring end gaps within the spec. I have to check my old rings I have and save as spares....
-Or what about Wiseco rings?

Finally running engine with RC pistons as this thread started with. Tank is not the final with good paint OEM style. Gas leaks sorted.

The engine is running with 3 NGK Iridium plugs and one NGK D8EA on 4:th cyl. (Bad mistake when tighten 3:rd plug, cracked the isolator, new ordered + 1 extra)

The ignition is not checked with strobe lamp either. Ordered together with carb sync tool

Carbs are also running rich on idle. Will set air screws better when ignition is finally verified, now according to PAMCO description, middle position.

Change attached files extension from jpg to mp4 and hear.

yes, they works if you download and then rename the file extension from jpg to mp4. This was plan B when I could not upload my minimized videos.
