This has to do with smoother manifold pressure.
If you need higher revs and quick response, then multiple carbs may help that, but if you need great low end torque, a smooth power band and easier tuning, then a single carb can give you that.
Ask yourself why most performance cars today have gone back to a single carb? Yes, gas mileage, but also smaller size engines need a wide power band and not just quicker response. Ask Harley-Davidson.
Just my take on what I have read. If you want to hear what Virago owners have said about this mod, go to YouTube and Search on: "Virago Single Carb"
Peace
