You need to go to Virago.com and check out the model you are buying.
Remember, these bikes are all well over 20 years old and Yamaha quit providing parts for them like a decade ago.
Breakers are always breaking up some bikes, but some of the electronics are aging out (potting materials, diodes, transistors, you name it) and good ones are getting scarce.
There was an old dude who unpotted and rebuilt black boxes as a labor of love, but now he's being loved on a higher plane and we do sorely miss him for many good reasons ....
The community can still support the bikes until something dies that you have to wait to find a "good 'un" that someone will part with.
The bikes still keep on kicking mechanically though -- doesn't seem to be much of an upper mileage number on them.
Their cam chains keep on keepin' on --
