I know it has been drilled into the ground, but I just put on my white bros pipe and k&n filter inside stock airbox and I'm getting popping. First of all, what size main are you guys using and did any of you change you needle? I'd like to mod the box, but with all of the water here in Florida, I'm a little nervous to. I'm from Utah. Can you get the jets at the dealer or do you have to order them from polaris? Oh, I forgot to mention. When I bought the quad about a week ago, I asked the dealer that when I change over to the pipe and filter, what size jet should I use. He told me that he has sold a lot of pipe and filter setups to people and they did NOT have to change the jetting. That's bull. Their bikes have to be running like ****. Thanks for the help! I'd really like to get away from the trial and error process if I could! [img]i/expressions/face-icon-small-wink.gif[/img]
