Description: This book is the bible for improving the performance of Evo Sportsters (4 and 5 speed models) and Buells of that era. Whether your intent is to improve the existing factory parts or install something from the aftermarket, author Kip Woodring explains not just which parts to buy, but why. Fourteen chapters cover: History, Planning, Exhaust, Induction, Ignition, Charging and Starting, Gearing, Valvetrain, Cams, Heads, Cylinders and Pistons, Flywheels, Oil, Transmissions and Clutches. Not just another hop-up manual, the Sportster/Buell Engine Hop Up Guide includes an in-depth analysis of important topics left out of other books. Issues like oil and oil friction, combustion-chamber design, camshaft trade-offs, valve gear weight and much more.
