Jetting Problem!

[rooster300ex]

U can see the mods i have below. anywayz i bought the advantage performace atv power up kit. and i did the stage 2 with the airbox lid off. ok when i'm just curising about 1/4 throttle it cuts out,and if i nail it in 1st and hit second then third it like stumbles right at the first of every powershift. what do yall think.
