The Rupert Ratio Unit Single Manual Volume 1: The Engine for BSA C15, B25, B44, B50 and Triumph TR25w is the new updated version of the previously published Rupert Ratio Unit Single Engine Manual.

After parts manuals, this book is the most important book to own if you are working on a BSA unit single!!

This new edition is identical to the previous book but has an additional section which provides some further information on the Vertical Oil Pumps, Low Oil Pressure, B50 Oiling, C15 and B40 Steel Flywheels, Wide Ratio Gears; C15/B40 Distributor Engine Inner Timing Cover 1959 to 1964, Clutch Centre Base Plate, B25 Tuning Tips, and Tuning Tips to make the 'umble ceefer fly.

Armed with this book even the least experienced 'spanner man' 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!

The Rupert Ratio Unit Single Manual Volume 1: The Engine 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.

Rupert Ratio is a long time contributor to the journal of the BSA Owners Club, The Star, on technical matters relating to BSA Motorcycles. He is also one of the many 'Agony Uncles' for members of the club, i.e. a technical consultant who can offer advice and assistance to club members when their beloved Beesas are beset by mechanical afflictions. He carries out the latter role under his real name, Dave Smith, who is a design technology teacher by profession.
