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.
