you need to adjust the air screw.also use a foam filter it will flow more air and you need an outetwear cover.

If you remove the lid you really do need to rejet.

If you're running the stock pipe, it will bump you up to a 125ish main. You'll also need to slightly enrichen the idle circuit.

Buddy tried this with his 300EX after I did it with my LTZ. I gave him a K&N and we played with the jetting but it didn't really seem to make much of a difference. The trade off wasn't worth it based on were the airbox is in relation ship with water and mud. On my LTZ I have a power lid and the airbox is more under the seat. The EX is pretty exposed.

If you cut a hole or take off the lid you must rejet or burn her up.
It's easy to rejet just do a few searches and learn. Heres a picture of mine that I cut out and slipped over an old pair of pantie hose that I had laying around. It works real good. I got an outwears cover for my Z400 and it works real good also. REJET!
