1972 Yamaha AT3 Service and Repair Manual

There is one factory manual for this machine and it is LIT-11613-14-01. The bike is the 1972 AT3, code AT3.

Also covered

AT1, AT2, CT1, CT1C, CT2, CT3, LT2 and LT3, in the 1971, 1972 and 1973 model years. Yamaha grouped them because the mechanical differences are narrow, and the book handles those differences with model-specific notes rather than separate chapters.

Content is straightforward workshop reference. Maintenance schedule, engine and transmission work with the inspection figures needed to judge wear, ignition timing and carburettor settings, torque tables, wiring diagrams, and troubleshooting arranged so you follow a sequence instead of replacing parts in hope. For a restoration, being able to look up a clearance or trace a circuit properly is the difference between a running bike and a project that stalls. Confirm the AT3 code before relying on a figure.
