Answer
Hi Don.
 Backfiring has nothing to do with the carbs 99% of the time.  With the Virago, synchronizing the carbs and making sure that the valves are done right will correct the problem.

The Virago also has another infrequent problem, where it will, on occasion, drop one or more of the needle valves in the carbs, requireing you to pull the carbs apart and reseat them.   The symptom that indicates that this is the case will be that the bike is suddenly running rich on one or both cylinders and will not run at correct speed and power.

Start with those things and see what happens.

Good luck.
