1979 Yamaha G1-A (CARB 2-STROKE) Service and Repair Manual

The 1979 G1-A is the earliest car in this batch, and Yamaha documented it in manual LIT-11616-G1-AE under model code G1-E.

Coverage runs 1979 to 1981 and includes seven variants, the carbureted G1 cars and the 36-volt electrics. Yamaha wrote one book for the launch years, so the procedures shared between those machines appear once.

Given the age, the specification tables carry most of the value. Service limits tell you when a component is finished, torque figures keep fasteners in aged castings intact, and the periodic maintenance schedule shows what the factory expected to be inspected. Around those sit the repair sequences for the engine, clutch, brakes, axle and steering, plus the complete factory wiring diagram. No specification here has been restated or updated by anyone other than Yamaha.
