I just bought a 1975 Honda CB550 K, which I love. It came with an extra gas tank, a Super sport with nice orange flake finish. The tank fits great as a replacement for the old tank (old tank needs to be repainted) but of course it interferes with the seat.
So I wondered if I find all I need to do is find a supersport seat, or if there will be additional modifications.
Great forum, I have been reading all the stuff here, gonna take some time to read it all, but great great information.
