Hi, I have a 1971 Honda CL 350 that we had running two years ago until we blew a hole in the cylinder. I want to rebore it but am also looking into buying a working engine. I am able to get a CB 450 engine. Will that fit in the CL 350 frame? I know the CB and CL are the same but is the 450 larger then the 359 and too big to fit in the 350 frame? Thanks
