Dude, do you have a pic of that Xl600. My stepdad has an 84 sitting in the garage that I got running a few years back, but then the cam skipped a tooth (that's what originally sidelined it, he thought it had seized) and now he won't let me work on it. I think it needs either a camchain or tensioner ($150 total). He owes me money so I think I might be able to get that instead, and I'd love to see a modified one for ideas. Thanks, Jimmy.
