very nice that you have a little air box to protect that nice little filter from water and mud.. id love to have a air box..

but fair warning, you might be able to squeeze by with that air filter and not doing a rejet.. but should you have a aftermarket exhaust installed DO A REJET BEFORE REALLY RIDING..a lot of times these quads come from the factory running extremely lean, if you add to that lean condition buy doing free flowing upgrades such as intake and exhaust.. its youre motor that pays and it could pay that bill a year from now or 3 days from now.. besides when you do upgrades you dont really take advantage of the extra power untill you do a rejet, and even doing the rejet adds a little power of its own..

keep checking youre spark plug to know what youre air/fuel ratio is right or lean
