Hi i just bought a brand new 04 300ex. after i break in the engine a little, i am looking for some upgrades. i want some speed, more accelleration than top speed but i still need that top end. Can anyone give me some specific upgrades that are most beneficial for my quad. thanks.

 

Intake and exhaust.

More specific a pipe air filter and new carb jets.

 

specifically like as in what brand pipe what filter and what carb jet what brands work best with the 300ex thanks

 

First thing, is get rid of the 22 inch baloon tires and go with a flat profile 20in tire like holeshots or something. The get an exhaust (I would suggest a White Brothers E-series or a Pro Circuit T-4), air filter (K & N or Uni), and rejet it (Dynojet Jet Kit).

 

Yeah I have 400ex tires on my 300ex and they work realy good for a stock tire. My friend just bought a set for his raptor because he likes them so much!
