Backfiring during acceleration

2003 Vstar 1100 Custom:
I purchased max air PMS screws for my Carburetor so I can adjust them on the fly. I have a clymers manual that states europian and Australia models are 3 turns out on both carbs. Well I'm not sure that's right as I turned out both to 3 turns and am getting backfiring on acceleration through first and second gear. I do have a cobra exhaust on it so I'm sure it must be adjusted but I'm not sure how many turns out I need to be. I'm assuming its running lean is why it is backfiring but at 3 turns out seems it would run rich. I'm no expert jut wondering if anyone has any insight. Also I have to remove the air filter housing every time I want to adjust them so it's not a ride and turn thing, gotta make a short loop around the neighborhood firing off shotgun blasts to pull back in park it and remove the air filter housing to adjust it. Any thoughts and tips are appreciated. Thanks guys
