I just acquired my 1980 XS650 street tracker with 750 cylinders, mildly ported head and XS Performance Cam. He put 1270 miles on it since the build. Originally, the bike had approx 7500 miles on it. What do I need to understand about periodic valve adjustments? Obviously, I cannot just open a Clymer's manual for it! Is there a break in? Should it be checked soon? Or do I have multiple thousands of miles before I even have to consider this?
