Single carb on a twin.

[BMWST?]

Not to be insulting but you're right - you're not knowledgeable enough. Car engines of four or more cylinders will have a pretty constant draw on a single carb due to the evenly spaced firing intervals.
Twins in cars (fourstroke) have invariably been 360 degree cranks - so even firing intervals which lets you use a single carb.
The staggered firing intervals in a 180 deg twin will inevitably result in one cylinder losing out due to poor distribution of the mixture.
And as I said before - the bigger the cylinders involved, the bigger the problem.

thanks for the clarification i thought that the cars would provide nearly constant draw

I did quite fancy trying a single anal 930 on an old GS500 suzuki

I'm presuming that Suzuki had a 4-1 with a nice waist height outlet then?

I thought that was a high scoring move in snowboarding.....
