I think big carbs are the sort of thing you try and do on your "second" NSR. It's really, and I mean really difficult to better the OEM carbs, and for a daily/streetbike, I can never see the point.
There's a guy in Japan who's put fuel injection on an MC18... that's pretty trick, seems to run OK in the videos, so pretty much anything is doable, but I bet it's not as good as standard carbs.
The PGM is just so well integrated with the ignition and fuelling. Bear in mind too, that the PGM controls the RC Valve, and takes an input from the TPS (which most big carbs don't have). While setting the TPS to a fixed position "works", the way the PGM reads the TPS and translates the input to RC output isn't as simple as that.
