The virago carburetors are somewhat tricky to clean properly. I have an 86 Virago 700, which has a "tube jet" instead of just a pilot jet. I had to use the properly sized guitar string to clean these out. Carb clean wasn't enough. Also, there's some bad advice floating out to drill out the pilot jets. It's possible your carbs have these drilled out ...

Is the fuel line pinched or clogged? What about the ...
