So my budget is 200$ a month, i have a stock ltz 400 2012 limited edition, the only thing i did was put a 15t front sprocket on. it was a 14t. i don't wanna buy a new pipe im just looking for overall power upgrades like i was gonna buy a after market exhaust tip just to decrease back compression. i would like some links to some good upgrades for my atv. i would like to know easy upgrades. i don't know anything about a valve upgrades or like cams or rev things but i can get someone to put them on so please post links of things that are cheap and pretty easy to install for upgrades thanks
