I in stalled a K&N air filter on my 06 pred 90 but it did not do so well because it just bogged down as soon as the high end hit at all. so I changed the jets. it had a 82.5 stock so I wet up to a 85. but it did the same thing so went up to a 90. same thing. is there something I am not doing right?

 

I put a uni-filter on my sportsman 90 and had to go to 110 on the main jet

 

Yep start with a 110. The K&N lets ALOT of air compaired to the stocker.

 

well I ordered the 100 and 110 and I am thinking of narrowing the hose connecting the fillter, allowing some vaccuum and keeping the filter on since we ride in the sand dunes I need an outer wear and a good filter. but to continue my question. what will I do when I get a new pipe. because I dont know where they sell anything more then a 110. it was hard enough finding the 110

 

hetricks or wrh, just to name a couple, can sell you bigger jets, or if need be, a bigger carb
