Actually, Vizard says its quite the opposite, that the movement of air
through the single carb sort of sets up a "mini ram" effect from cylinder to
cylinder that twin carbs don't have because the air isn't moving as fast or
as often. I don't know, but it makes good reading!

Subject: Re: what about a single 1.5 su?
Although no-one says so, I would expect that at higher rpm the advantage
swings back towards twin carbs because the ports are 'seeing' the big single
so often it has hasn't seen one port before it starts to see another. What
that rpm is I can't guess at but bet it is higher for a 998 than a 1275,
1380, etc.
