milosusa i have done more than just a clamp on my filter. I also put a k&n filter with sensor safe filter oil and i cut an outerwares pre filter to fit over the opening on the air box. also have an outerwares pre filter on the k&n filter. also instaled holz racing air box bed seal. Dealer also did recall fix. and i also greased the lid on the air filter housing. I did all of this fresh before i went on the kentucky black mountain ride and i still got a little dust film past the the filter in my air intake tube that go's to the throttle body. my air filter is vary dirty the only reson i can think of for causing this is because of the location of the filter housing. thay put it in the middle of a dust cloud. all of my atv's wear tuck under the seat or installed where the gas tank would have gone if the tank was moved to rear of the unit. this helped box the filter housing in and the housing wasent setting in a dust cloud. I need to look at this filter housing and see if it has a drain hole big enough to let dust in because i have sealed everything else. im woundering if the dust came in through the hole and was to much for the filter in that spot. i havent cleaned my filter yet and i will look at it and see if there is a heavey dust spot in one area. however to do all this to keep dust out is not right and polaris needs to fix it. In case your woundering i was on the trail for 10 hours. and my rzr did run great. for the most part i think my set up will work but in heavy dust conditions it dident keep every bit of it out. and if you do filter housing mods that pemently change the set up you void the warrenty. now that being said what do you have to say MR DOUBTY MOOSTAFFA. If the rzr dident have an air filter problem and if it was working like the other units on the market you wouldent hear me bitching. yes all units let dust in but the rzr is letting enough in to get pass the filter. and the way i have my rzr set up and its still getting past the filter. It would have to be getting alot of dust in one area or somthing. anyhow polaris should relocate this filter housing and it was cought quick enough so i think it shoul be free of charge for all rzr's. It's not our falt they dident fix it before too many got sold. remember the ford explorer. everyone stick togather and if you are not with us on this go to another post because our minds are maid up on this and we dont want your negativity on this one.
