altering the main jet will make no difference to the low revs you mention.
My 2002 883R still farts even though I have lowered the opening position of the butterfly valve.
The problem seems to be to balance the amount of petrol that its sent into the carb via the accellerator system against the amount of petrol sent in via the butterfly valve(which controls the amount of lift on the needle) at low revolutions.
people have mentioned adusting the fuel/air mixture, but I think that may affect your petrol intake throughout the full throttle range.
Since I'm getting over 60mpg with my current settings I'm more than happy to put up with the occasional spit-back.
not a very technical answer to your question I'm afraid, but every bike and the way its ridden means there are so many different settings for your own way of riding that it will be almost impossible to give you a definitive answer to cure your problems.
hope this helps

Yep that is true the pilot jet.. is what controls it the most.... I'm sorry but i don't get what you mean with lowering the the opening position of the butterfly valve. I mean isn't' that just normal idle control -- i.e. more or less open butterfly valve -- more or less rpm so to say? Or am I to much thinking like it was a car carb? Like a quadrajet or a SU
...
I assume you mean adjusting the main jet will adjust the fuel/air mixture, throughout the full throttle range. Adjusting the as in screwing in and out the idle adjustment screw only affect it at idle if I'm not totally wrong...
