Hi,
I'm very slowly rebuilding my 1977 F2. I had a phone call from the machine shop advising that the new piston rings are to small and I need 64mm.
So if I have researched correctly the bike has had a 812 big bore kit fitted at some point. Does anyone know where I can buy 64mm piston rings from? I did read that the cb350 piston rings would work, is the any truth in this?
Thanks for your help
