Yamaha's service volume for the 1974 Moto Bike is part number LIT-1161J-60-00, and its coverage is limited to that single model year.
Because the scope is one season, the specifications are not diluted by later changes. What the book gives is the factory service content for the machine as built: the order in which assemblies come apart and go back together, torque values for fasteners, clearance and adjustment figures to measure against, wiring diagrams for the electrical system, and troubleshooting sections that move from a symptom toward the component responsible.
When you need to identify the right reference for a 1974 Moto Bike, LIT-1161J-60-00 is the number to quote. Anything beyond the model, the year and that part number is not stated in the record, so treat those three as the facts to confirm before you rely on a figure.
