RD400F is the last of the line, and it is covered by the same volume as the rest: Yamaha part number LIT-11616-RD-40, written for 1976 through 1979.
For an owner that has a real benefit. The book records what changed across the run, so when a component on the F differs from what an earlier parts list shows, the specification tables tell you which figure belongs to which year rather than leaving you to guess.
Coverage is the dealer set: tune-up and maintenance specifications, engine removal and complete teardown with torque values, Autolube and fuel system service, ignition timing, clutch and transmission work, then the chassis with fork, swingarm, wheel, brake and chain service limits. Wiring diagrams and electrical troubleshooting are included.
Before ordering, match the RD400F code on your machine and check that the listing you are looking at quotes LIT-11616-RD-40.
