I think most of us are here for fun, not "investment", but I still think it's nice to get back to original if possible. none of mine meet that standard - some are close, at least period, and fun to ride.
sykerocker - my BSA rode better only because now it had a straight frame, the rear was trashed when I bought it. never quite completed it to my satisfaction, and left it in charlottesville after b-school. wonder where it is now?
