Donny's Unauthorized Technical Guide to Harley-Davidson, 1936 to Present: Volume I: The Twin Cam

Donny Petersen offers workable solutions for whatever ails your 1999-topresent Harley-Davidson. Graphics, pictures, and charts guide the reader on a sure-footed journey to a thorough understanding of the H-D Twin Cam.
Petersen’s insight makes technical issues understandable—even for the motorcycle novice. In easy-to-understand language, he examines what’s right, what’s wrong, and what’s “just okay” about the Twin Cam power train.
Volume I: The Twin Cam is the updated first volume of Petersen’s long-awaited Donny’s Unauthorized Technical Guide to Harley-Davidson, 1936 to Present series. This twelve-volume series by the dean of motorcycle technology examines the theory, design, and practical aspects of all things Harley-Davidson.
Having ridden hundreds of H-D Flatheads, Knuckleheads, Pans, Shovels, Evos, and Twin Cams across four continents—and doing all of his own roadside repairs—he has acquired a wealth of firsthand practical knowledge that he now shares. He dispenses streetwise tips and walks readers through detailed service procedures—including everything from porting and polishing cylinder heads to performing simple maintenance, like oil changes.
