"RIDERS' INSTRUCTION MANUAL" This is not just a manual on how to operate the bike, it is also the basic mechanical manual as well, from setting points to removing the pistons, on both side-valve and overhead valve models. They did it right back then. This is one RARE piece of history. It is complete, color on cover is good, lettering good. The center-panel page is loose from the staples, an easy replace: remainder is excellent.
