Got my hands on a 1978 XS650 thats been sitting in a shed for 15 years and looks like it was pretty shagged prior to that. Always fancied a build out of an old bike though and these seems pretty versatile. Would make a pretty cool street tracker or cafe racer.
What I am trying to decide is whether to get the old engine rebuilt (or get one that runs) or actually chuck in a fuel injected lump from a newer bike. It'd still have to thump - maybe an XT?
Has anyone had a bash and trying to put a different lump in a XS frame?
