I just bought a K&N,Adapter Plate and Pre-Filter off Ebay. I want to put this on so My Motor does suck dirt incase I put the lid on wrong. Do I HAVE to rejet I dont really want to because I'm buying a pipe later on down the road and dont want to jet anymore than I have to.

EDIT: I will be leaving the lid on, I know I will if I take it off now. I will take it off when I get My Pipe.

 

If you bought a k&N airfilter you are talking about you will need to rejett. Anything you do that is fuel/air intended you wuill need to rejet [img]i/expressions/face-icon-small-smile.gif[/img]

 

You probably should rejet. And hell with it get some experience because unless you are really lucky or a magician you are gonna do it quite a bit anyway to get the right.

 

If you don't make any changes to the air box you'll probably be alright.

 

Your just putting a K&N filter on correct ???? If so you DON,T need to rejet, unless there are big mods. to the airbox. The Raptor, like most stock bike,s run a little rich from the factory. Don't worry an put your filter on and ride. If and when you change your exhaust you'll have to rejet it then.
