Posted by: justinmill14

I am wanting a little more power and speed in my 300ex, but not wanting to spend mega bucks. I was wanting to know how much a jet kit would help the fourwheeler. And which would be better, stage 1,2, or 3?

My 300ex is 2000 model, has hmf pipe on it, k&n airfilter, and wiesco pistons. Thought I would give that information incase it may help with which jet kit to get.

jet kits don't add power...they are to tune your carb...to get your air to fuel ratio correct...if this is off, then you will "gain" more with a jet kit by correcting an issue that you didn't know about...

read this...then if you think you still need a jet kit...order from them...
