Cycle Works, LLC
If you've ever been discouraged by the number of special tools required to work on your vintage BMW, Cycleworks is your solution. Formerly owned by Ed Korn, Cycleworks manufactures these special tools in a state-of-the-art machine shop, but what is manufactured far surpasses original factory tools in both quality and ease of use. Cycleworks also sells four rebuild (how-to) videos for top end, bottom end, transmission and wheel work. The tools work well, and come with instructions. I also bought two of the videos, which have probably saved me hours of frustration.
