I take it you mean you cured a missfire but still have a stutter directly after having the carbs apart? As the air filter is the easiest to do i would do that first, making sure to clean and re-oil it properly, not over oil and use proper k&n oil. Also that the refitting is correct as the k&n on mine seemed to sit a bit high for the lid to fit snug until i gave it a firm push. If that don't help i would check the fuel pipe is not kinked anywhere and that the tap is fully on. I think the thing here with it just in 1st and 2nd is the speed of the pickup of the revs demands max fuel flow more than the higher gears and especially at those revs. Fazerider has a good point about float levels.
