1977 Yamaha XS650 Service and Repair Manual

LIT-11616-01-52 is the part number to quote for 1977 XS650 service information. The bike is listed in that volume as XS650D, and the book runs from 1974 to 1977, making this the final year it covers.

Sitting at the end of the run means the accumulated changes are already in the text, attributed by code, so the specifications you work to are the ones that applied when the machine was built.

Contents in outline

Reference specifications and periodic adjustment come first. Engine overhaul follows in factory order, with clearances, service limits and reassembly torque; then clutch, transmission and drive; then forks, rear suspension, wheels and brakes. Carburetor setting and ignition timing are procedures with stated values, and the electrical chapter pairs component testing with a wiring diagram drawn to the harness.

Check that your frame or engine reads XS650D.
