Auteur: Donny Petersen

Donny is the Winner of the 2012 International Book Awards. Donny established and has operated Heavy Duty Cycles in Toronto, Canada, since 1974; his monthly column “Techline” has appeared in American Iron Magazine since 1992. Instructed privately by Harley-Davidson engineers, Donny has taught mechanics, designed tech-school curricula, and authored student-licensing examinations. 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 first hand 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. A Toronto resident, Petersen now writes his 12-volume technical encyclopedia. Donny enjoys riding, mountain trekking, boxing, and diving.
