This is the 1989 G2-AD, a carburetted car with code G2 - AD, documented by Yamaha in LIT-19616-G9-93.
Coverage in that manual is deliberately broad: 1985 to 1995 and thirty-one further models, taking in the rest of the carburetted G2 line, the 36-volt G2-E cars, the G9 FLEET MASTER and FLEET CLASSIC range, and the ADVENTURER FAIRWAY LOUNGE. Yamaha printed one book because the cars were built from the same parts.
Engine and carburettor procedures, clutch and drive service, brake and steering work, wiring diagrams as the harness was built, and troubleshooting arranged by symptom are all set out with the torque values and service limits the factory specified. That level of detail is what separates a proper repair from an approximate one on a car this old.
Confirm G2 - AD on the plate first.
