Harley-Davidson EVO Hop-Up & Rebuild Manual, is a must-have for anyone who wants to put wrench to an EVO V-Twin. Each section covers a specific subassembly of an EVO motor. The reader can pick and choose which chapters they need at the time, be it installing a new camshaft, or a top-end kit.

The crew at R&R Cycles shows how to assemble: The Bottom End, Gearcase, Cylinders & Pistons and Cylinder heads. Written by Chris Maida, the man who put in nearly 20 years as editor for American Iron Magazine, with help from the crew at R&R Cycles, this book shows the reader not what to build, but how to build a rockin' Evo-style engine. If you're a rider or shop owner looking to do more work on EVO V-Twins, this is the book you need. From a simple rebuild to a complete assembly from scratch, the how-to information and photo sequences you need are contained here.
