Could you describe the controls on the left handlebar? I'm guessing that they may be the clutch, or throttle lock and choke or spark advance? Is it positive ground? Sorry for the stupid questions but you don't get to see many really cool bikes like that one around my parts anymore just the usual overpriced garish user friendly wanna bee's with sawed off pipes. Between this post and the one with the Red Matchless makes me want to build/ride some more.
