Hey dhall57 and Stev-o, I bought the bike from a guy in Nebraska. Other than the standard "this was garage kept for decades" spiel, I didn't learn too much of the history from him. I had to clean the carbs and I replaced filters and a few cables, but now it runs like a dream.
NewOldSchool, I was (and am) planning on heading over to the rally next Saturday. The only thing better than one of these machines is hundreds!
