You actually just modify your stock airbox. It is under the seat. You will notice that the front half of the airbox needs to stay because it holds the filter in place. However, the rest of the air box cover can be cut off and it lets more air in. It really helps the engine breathe. Some people buy a kit that allows you to remove the whole cover and the filter is held in place by a clamp.

HMF is the brand of exhaust that Warrior owners seem to like. I just ordered one off ebay for $227. This combined wth the air box mod will make a nice difference. They recommend that you adjust your jetting in your carb after doing these.

Don't worry about being new. I am 28 and this is my first quad so I just learned all this stuff. I enjoy learning about this and really look forward to the day I have a raptor 700.

 

thanks man......... when you say adjusting your jets you mean buying a jet kit right, and if so what kind

 

From what I have read you should just buy a main jet and not a jet kit. Stock, the warrior comes with a 145 main jet. Once you introduce the airbox and exhaust you probably need to be using a 150 or 152. To know exactly which one it is trial and error. After trying the 150 pull the spark plug and inspect. Judging by its condition you will know if you need to go up or down.

 

Also lift the needle up to allow for more fuel in the mid range as it will run lean on part throttle, I used a Dynojet needle, but the standard is ok , move the clip down two notches.

Do a run with 70% throttle, then hit the kill switch, and inspect the plug.

I was wondering about this. I might take my carb off now and get this done so it is ready when my exhaust comes in.
