Book excerpt: Old Skool is kool. No theme bikes here, learn how to build a real American motorcycle based on a Panhead, Shovelhead or Evo engine. Don't buy expensive new parts, build your own bobber or chopper from mix-and-match swap-meet parts. Written by Kevin Baas, the Kennedy High School shop teacher with the Build-a-Chopper class, this book takes a back-to-basics approach to motorcycle assembly. As Kevin says, if you can't buy it cheap, adapt it, and if you can't adapt it, build it from scratch. The author explains which engines fit which frames, and which transmission and primary drive is the best fit behind a particular V-Twin. The back half of the book includes three start-to-finish assembly sequences utilizing early and early-style engines, drivetrains and components. This 144 page book uses over 350 color images to illustrate kool parts and even kooler motorcycles.
