I normally like this series of books because they normally take you by the hand and show you step by step what to do. This book however was the biggest dissapointment. Intead of focusing on explaining rake and how to select frames or actually chopping a bike, the book is filled with links and names of places to purchase parts ( I have the Internet for that). IMO, the book should be called how to sell a chopper! It's all advertisment. The history of choppers is more about explaining who sells what and of course including a link to their web site. The author even talks against the Teutuls (OCC).There are not many books out there on building choppers and modifing motorcycles...I would have expected more from a "Idiot's series" book. Too bad.
