1990 Yamaha G5-AF "SUN CLASSIC"(CARB) Service and Repair ...
Yamaha listed this 1990 car as the G5-AF Sun Classic with carburetion, code G5AF, and gave it the service manual numbered LIT-11616-07-10.
The factory naming for these cars varies between listings, which is why the part number matters more than the title. LIT-11616-07-10 covers 1990 to 1995 and every G5 variant Yamaha recorded for those years, carbureted and 36-volt DC-motor alike.
The manual takes each system in turn and gives the order of work, the measurement, the limit and the torque. Carburetor and engine service, transmission and drive, brakes, steering, suspension, then electrical with the wiring diagram and fault-finding charts. It assumes you intend to do the job properly and tells you what Yamaha required at each step, rather than offering general advice about golf cars.
