1980 Yamaha GT80 Service and Repair Manual

LIT-11616-GT-81 again, this time for the GT80G of 1980. The book runs from 1978 to 1981 and takes in the DT80 alongside the GT80, so several small Yamahas are served by one factory reference.

Fitment

Confirm GT80G on the frame plate; that code is how the specification tables are indexed.

Contents

• Wiring diagram plus component test values
• Troubleshooting by symptom

Yamaha kept this volume in service for four seasons, which tells you how little changed mechanically across them. Nothing in here is padded out with general advice. It is the procedure set and the numbers, which is what makes the difference between a machine that runs and one that runs the way Yamaha set it up.
