I researched the book on the web and I like it for the fact that it spells out the job, the skill level needed, the amount of time it will take, and what other jobs you should be doing while you have it in that particular state of teardown. It is understandable for the novice and with this and the shop manual for the bike, I don't believe there would be much problem for an average guy to accomplish quite a lot on his own. Every project is broken down with photos and it tells you what skill level you require, making it easy to decide whether or not to tackle it yourself, or bite the big one and pay your local Harley mechanic. I'm impressed enough with it I ordered the Twin Cam one and a couple for my buds.
