Oh yeah- If any of you 350 guys need piston rings, there's a set on eBay right now. Don't have the link, just search CB350F. I put a set in mine, couldn't find any aftermarkets, so I ordered them from a dealer. He quoted me "$42 a set". Well, his definition of a set was different than mine, he meant a set for a single piston. Damned near floored me when I wrote a check for $175 for them.
