Yamaha's service coverage for the carbureted G5 Sun Classic sits in one volume, LIT-11616-07-10, and the 1993 car is listed there under model code G5AJ. Confirm that code on your machine's plate and you know you are reading the right procedures.
Coverage
The book runs from 1990 through 1995 and takes in eleven Sun Classic variants, both the carbureted cars and the 36-volt DC motor versions, including the G5-AF, AG, AH, AJ, AK and AM engine cars and the EF, EG and EH electrics. Yamaha treated the model as one family and documented it that way.
Expect the usual factory content: inspection and adjustment specifications, brake and steering service, engine and drive work with torque figures, and wiring diagrams with troubleshooting steps. For a car of this age the specification tables matter most, since guessing at a clearance or a tightening value is how these get damaged.
