Holes in the airbox?

I'm new to performance quads. I recently bought a Raptor, currently still breaking in (about 6 hrs or so on it). I have a White Bros. E-Series pipe on order and plan on jetting accordingly, but what is this I hear about drilling holes in the air box? Where? How many? What size? Is the improvement really noticable? also i am thinking about getting a K&N filter. I have one on my jeeps, will it help much on the raptor?

Re: Holes in the airbox?

putting holes in the airbox lets more air flow it but still keeps the filter somewhat dry and protected as opossed to removing the lid...probably 6 one inch holes is good i have heard that you shouldnt put them in the center only along the sides because if they are in the middle it actualy blocks air...if you dont ride where it is wet just toss the lid..

Re: Holes in the airbox?

When jetting ( I just did mine ) pending on your elavation , only go up one size in each carb. (you dont jet a 4 stroke like you do a 2 stroke)

On the air box of a Raptor , in the lid if you look down the snorkle you will see a plate that is blocking air flow , just cut out the plate and go with it IT WORKS WELL

raptor, do you mean the 2" wide rubber plate at the rear of the snorkel? also if i cut this out should i still drill holes? By the way i live in colorado and will be riding at elevations of 6000 - 8000 feet. i am guessing i need all the air i can get.

Re: Holes in the airbox?

yes thats the plate I was talking about , and no I wouldnt cut holes in the box . I would wait on the jetting also scence your at that elavation and talk to your dealer to see what jets are in yours ( see if they jetted for your area ) I'm at 2000ft and my jets were 140 and 145
I would get my pipe on it , cut out the flap , then see how she runs , if you need to rejet you will know , you will have a flat spot in your power at low RPM , also known as a lean miss , if you have this , get it rejetted right away you can cause severe damage to your engine if you let it go , if you dont have this (lean miss ) then keep a close eye on your spark plug to see how she's running (lean , rich )
