A. Yes, it should be a direct swap, with the possible exception of the TCI module. You'll also need a dash from the 750 if you intend to use the stock dash wiring.
Comment: This TCI difference can be overcome if they are different, but you'll need the schematics for both bikes to compare functions of all leads to the TCI module itself.

Additional Info: Note: The parts breakdown and service manual CDs that I had listed here are no longer available from Bill Wheeler due to his unfortunate death in December of 2004. His family may begin marketing them again at some point in the future, but that is uncertain. If you need any of the information that Bill had available on the XV Virago CD ROM, contact bykrmom because she can help you out with other sources of the information.

Our thoughts, prayers, and condolences go out to the Wheeler Family for their loss.

Ride On, Bill!
