This manual is a guide to parts interchangeability and high performance engine modification for Harley-Davidson V-twins. It covers all models from the mid-1930s up to and including 1983. It tells you which square pegs fit into what round holes, or how to make them do so with minimum pain. This book will enable you to build a motorcycle from a stack of more-or-less unrelated parts. It will also assist you in building your motorcycle for the greatest amount of power, the most reliability, or somewhere in between. This book can save you a tremendous amount of time, complications, and money.
