Hey guys,
I'm new, (n00b). Just bought my first cb750, rather, first bike and going to have a lot of questions. Firstly, I like the 1976 gas tanks more than my big old tank that came on my '77 k. Are they interchangeable? Cheers.
Welcome to the site! I'm not an expert on parts interchangeability, but I think it'll work if you use the '76 seat as well. I'd wait for someone else to confirm or deny.
