1993 Yamaha G5-AJ "SUN CLASSIC" (CARB) Service and Repair...
Midway through the run sits the 1993 G5-AJ, a carbureted Sun Classic with model code G5AJ. Yamaha's service manual for it is LIT-11616-07-10.
The same book was in use from 1990 to 1995, and its coverage includes the earlier and later carbureted cars as well as the 36-volt DC-motor variants. There was no separate 1993 volume, so this part number is the one to quote.
Content runs from engine and carburetor overhaul through drivetrain, brakes, steering and suspension to the electrical system, each with the factory's removal order, inspection measurements, service limits and torque values. Wiring diagrams show the harness as built and the troubleshooting charts move from symptom to likely cause. It reads as a set of instructions to follow, which is what a service manual should be.
