First, this problem is far from "harrowing"...it's just a matter of knowing what the heck you are doing when you mess with bike...or taking the time to learn how these thihgs works. These Mikuni carbs are probably the simplest, most basic and trouble free carb ever produced.
So....lets see exactly what we have.....
You said the bike had be re-jetted. That is a term used so loosely these days to mean anything from taking the carb off the bike to actually changing something and hopefully getting most of the pieces back in the right places. Usually if something was changed in a "re-jet" it was the main jets. But telling us it was "re-jetted" really means nothing to us at all other than there is a possibility that the carb internals might not be put back together right.....
There are 3 separate fuel circuits on these Mikuni's. Idle, needle and main jet. They work at different throttle positions. Find the throttle position with the issue and you've found your problem area. Then you just need to figure out if the problem circuit is rich or lean and make a simple adjustment to make things right.
So..... to do this right, please tell us the size of your current mains and pilots and the throttle position with the issue....and we may be able to offer a little advice.....without that, it's all just making wild guesses and assumptions.
