2" Intake snork?

U think the 2" is really necessary? I ran 1.5" for everything. The factory is already approx 1.5, I just tapped off of that. But I hear some people saying that u need 2".. Now Im kinda 2nd guessing myself. I dont have any problems with mine, but was just wondering..

It all depends on what you are doing with the bike. More air flow through the engine the better, in most cases. Its a very tight fit, but 2" can be used for the intake. I used 1.5" on the CVT and 2" for the intake. You can also add another 1.5" snorkel off the airbox to help it breath even more. Just hide the CVT intake under the pod and use the three snorkels coming out for the air box and CVT exhaust. If you plan on doing cams, headwork, pistons, etc. then you will need more airflow to maximize results. You already have probably the top flowing exhaust, why not let the intake flow just as well?

Good point.. I never thought of running 2 air intakes, and hide the cvt intake. I might just run the larger 2" intake.. DO you have any pics of the modification to the airbox that needs to be done? Im thinking holesaw?

Yeah, just use a holesaw. Its an awkward angle, but after you do a few you will be able to drill the hole just right without taking the box off. If your not comfortable doing that though, pull the airbox off and drill it. I will try to get some pics for you tomorrow or monday. I already have the bike loaded for a short trip today.

Sounds good..

Not very good pics, but gives you an idea of how to get the PVC in the air box. This was done the night before a ride about a year ago when I first got it, still needs the final touches but works for now.
