Welcome, cherry bomb, where in CA are you going after you finish your tour?
Best of luck w/ the shop. It seems that when these bikes go into the shop and the owner goes away, it turns into a "well, we're waitin' on a part, shouldn't be more than a week or two..." that just goes on for months and months. Hopefully you found one that's got a wrench with a passion for the older bikes.
