All the carb-cleaner in the world won't help if it doesn't get through the plugged jet. They WILL have to come off.
As I don't know the exact setup for the Virago, I can't really help you with specifics on removal. If you asked a Yamaha Tech - I'd be inclined to believe him. It's fairly easy to remove a stud (if it's not siezed).
Loosen all the fasteners holding the carb, use a nut from one of the other studs as a jamnut, and just turn it out with a wrench. Might take awhile, but how much time will it take just letting it sit, waiting for it to remove itself?
