The 1985 VMAX is coded VMX1200N, and Yamaha documented it in the manual numbered LIT-11616-VM-13.
That one volume was kept current for a remarkably long run, listed against 1985 and 1986 and then every year from 1988 through 2000. Yamaha revised rather than replaced it as the model continued, so the earliest bikes and the latest share a reference, with the text distinguishing them by code where a procedure or a setting changed.
Content is factory shop material. Specifications and torque tables come first, followed by periodic maintenance, engine and transmission overhaul in assembly order, fuel system service, shaft drive, chassis and brakes, and an electrical chapter built on the complete wiring diagram. Diagnosis works from symptom to test to a published reading, which is what a machine like this deserves when something is not right.
