Volume I: The Twin Cam
is the comprehensive first book that begins with a secrecy agreement with Harley-Davidson well before the release of the Twin Cam. Donny was one of the chosen few to learn about the new engine and motorcycle in advance of many H-D employees and all the dealers. Bill Davidson leads the team of seven engineers in charge of design, testing, and production who painstakingly taught Donny every facet of the new Twin Cam. In addition, Donny has worked on the Twin Cam 6-days a week ever since.
Donny Petersen offers thoroughly thought out but practical fixes and solutions for whatever ails your Harley-Davidson Twin Cam 1999 to present. Donny explains in everyday language what’s right, what’s wrong, and what’s “just okay” with the Harley Twin Cam power train.
