Rupert’s BSA unit singles engine book N/A

Armed with this book even the least experienced ‘spanner man or woman’ will be able to not only rebuild a BSA Unit Single, but make it go better and more reliably than even BSA thought possible! This book quite literally takes the BSA (and Triumph) Unit Single engine apart, then it shows how to rebuild the engine correctly. The book includes wiring diagrams, complete specifications, hundreds of illustrations, a wealth of invaluable advice and tuning tips to make your unit single perform! This book will also be of interest to all BSA enthusiasts since it charts the development of one of the last and most successful machines to come out of Small Heath. Long after the factory closed Unit Singles were still a competitive force in trials and motocross riding and many are still used for that purpose today.
