For the early Virago 750, the factory reference is publication LIT-11616-XV-90. The 1981 bike carries model code XV750H, and the same book carries 1982 and 1983 as well, all under the Virago 750 name.
Work on a machine this age usually starts with diagnosis rather than parts. The manual's electrical section gives the diagrams and test values needed to chase a charging or ignition problem properly instead of by substitution; the engine chapters give service limits, so you can measure a worn component and decide rather than guess.
Before ordering, read the code off the frame. XV750H is 1981. If yours reads differently but still says XV750, LIT-11616-XV-90 remains the right publication for the three years it covers.
