First of all : sry for the slow reply.
Second of all : Carborater Adjustment, Idle Screw, and Mods.
First 2 aren't even english to me (lol)

and mods well none. My quad is fairly new and even if I wanted to make any mods I wouldnt know where to start.
the idle screw adjusts how much gas you use while idleing i think, may be wrong. If you havnt adjusted it then its probably pretty low. Most dealors have it low, mine was when i bought it. If you search around google, you can probably find more on it, and the carborater adjustment.
