HAYNES BSA UNIT 1CY 58-72
Haynes workshop manual for BSA unit-construction single-cylinder motorcycles, 1958-1972.
This is the Haynes workshop manual covering BSA's unit-construction single-cylinder machines built from 1958 through 1972. It's a shop reference, not a mechanical part, but Ed keeps it on the shelf because it's the kind of thing you want next to the bike when you're sorting out a rebuild or trying to figure out what a fastener or bracket is actually called.

The manual walks through the engine, gearbox, electrics, and chassis for that run of BSA unit singles, with the usual Haynes teardown photos and torque specs. If you're working on one of these bikes and don't already have a manual in the toolbox, this fills that gap.
We list it under JRC-18-050, and it also shows up in older listings as part number 127 - same book, just a different catalog number depending on which list you're working from.
