Found a 1986 Yamaha FZ600 for sale. Going for $800.
I just broke my right hand mirror trying to get it off because I assumed it was the normal right threaded. Turns out it is left threaded. What a joke. Snapped it off for no reason whatsoever.
It appears to have the same part number. I compared a 1990 xv750 with a 1986 xv700 and they both have Yamaha part number 3CF-24730-10-00. I have an '86 xv700 so I'm always shopping for interchangeability. I use bikebandit.com or servicehonda.com for their OEM part finders. I can select my Virago and get the part number then start comparing to other models and years of the Virago. Helps a lot with searching online and on ebay for parts.
