i had this problem on a car one time, and maybe it's something to check for...
it ended up being an old vacuum line that had lost enough of it's rigidity that when the revs went up too fast, the vaccum inside the tube would suck it completely closed, cutting off all the air (or was it fuel? damn it sucks getting old!).
anyways, if any of the lines are old enough that the rubber is flexing too much, might cause this. i know nothing about a virago, though.
