Banshee carbs 28 keihin pwk jetting

[Zoolxxxzool]

I have a stock  banshee motor, stock bore(64mm wiseco)stock stroke, stock intake boots with stock cross tube, v force 4 reeds, timing it set at 10, 120-125 psi, pro circuit pipes, jetting/pilot 150,42 I’m running a set of 28 keihin carbs, k&n filters. Air screws are at two full turns out,and clip on needle is set at second notch from top, Elevation 505’  idles fine and are sync, but shee has a bad bog going up hills and will act as if bike could be needing more gas when just cruising a open field until you go up pass 3rd gear clears up pretty well, can someone give me some advice that will put me in ball park thanks in advance.
