1971 Yamaha R5 Service and Repair Manual

The 1971 R5 has its own reference. Yamaha part number LIT-11612-80-99 covers that model year alone, and the machine is identified inside it by the code R5B.

Working from a single-year volume removes a certain amount of doubt on a bike this old. The clearances, torque values and adjustment settings printed here were set down for the R5B rather than carried across later revisions of the model. Each major assembly has a stated order for coming apart and being rebuilt, the wiring diagrams cover the electrical circuits, and the troubleshooting material moves from a symptom toward the component responsible.

Check the R5B stamping before you rely on a figure, particularly if the bike has been through previous owners and mixed parts. LIT-11612-80-99 is the number to quote when you need to be certain which R5 volume is under discussion.
