Clean the carbs, make sure you get all the jets totally clear. My Virago's carb was gunked pretty bad when I got it.
Other problem you might encounter is the infamous starter issue.
Cleaning the carb will cost whatever carb cleaner + time if you do it yourself, though a gasket kit would be nice.www.viragotechforum.com
