Yamaha's three-wheeler line starts here, and so does the paperwork. The 1980 Tri-Moto carries model code YT125G, and the factory service manual for it is part number LIT-11616-01-89.

Coverage is a single model year, which for a first-season machine is what you want. Nothing in the tables belongs to a later revision, so a specification you read applies to the quad in front of you.

The book works through routine service and adjustment, engine disassembly and reassembly with the clearances and torque values Yamaha specified, carburetion and ignition settings, electrical testing, and chassis work on the steering, suspension, wheels and brakes. A wiring diagram is included.

For a machine of this age, original documentation is often the only reliable source left. Confirm YT125G on the frame, note LIT-11616-01-89, and you know the reference matches the hardware.
