Most cars only have a single carburetor and/or throttle body. Therefore there is nothing to balance.

Because most cars feed the cylinder intakes from a manifold branching from a single throttle body or carb. Most bikes have a carb or throttle body for each cylinder for higher performance. There are exceptions to each case.

The latest one really doesn't. There's just a single air balance adjust, I suspect it seldom needs touching.

I think it's mainly been a matter of the technology they can fit on a bike and have work reliably.

You could for example put a pressure sensor in there and have a stepper motor drive the balance screw - problem is the pressure sensor is more likely to drift than the mechanical bits.

Just a comment, but gluing down the adjust screw on my K6 made it stay in balance for a lot longer - I suspect the adjusting screw moving was more of a problem than wear.

higher performance? i guess that means we also sacrifice efficiency, since there are cars which weigh a heck of a lot more than these bikes do yet get better mpg.

of course there have to sacrifices and i still love my V. just sayin...
