Something I forgot to mention; Those air screws only affect the Carbs from Idle up to AT MOST 1/4 throttle, anything higher than that and you start going to the needle and then to the mains. Also, there are easy ways to check to see if your air screws are flowing symmetrically, counting out and matching each side equally is only a start and probably won't be your final setting. There's about a half turn difference between my right and left carb air screws, so don't get hung up thinking that equal turns are the best setting. have fun, when they're set up right, THEY ROCK!
