Hi There! I've just recently purchased a 1978 XS650 parts bike, as well as a 1978 frame with a wassell gas tank, rear fender with sissy and a set of Panzer handle bars. I also purchased a 1976 "rebuilt" engine. I'm very excited to have found this forum as this will be my first bike build and i'm sure the site will be extremely helpful. I'm working in a fairly cramped space but after spending the last week tearing down the parts bike I think it's going to work out fine. The tearing down of the parts bike was fairly easy, one thing that I will need to figure out is that the frame i'm using is a rear disc brake set up and i'm hoping to use a rear drum wheel so I need to start searching how to do the conversion. I also think I have an issue with the "rebuilt" engine as I took of the valve covers and noticed rust on the rocker arms and rust on the cam. The engine looked so clean when I bought it that I didn't really check it over. Maybe it was rebuilt but then not stored properly?. I have the engine from the parts bike so i'm guessing I could use the cam from it? I'm hoping to have a rolling chasis done this week and then have to figure out what the next step is? I'm super excited and my goal is to have it finished in time for the CVMG Rally in Paris Ontario in June. Thanks!
