I have a 2006 ltz250 with a twin air ,dg stage 1 exhaust, and maxxis razar tires front and back.. When i take my airbox lid out my quad doesnt seem like it wants to run but from what i hear when you take the airbox lid off it gives it more power. I just need to know why mine doesnt want to run. i kinda thought jets would help but i dont know.

thanks, hammertyme
