We’ve found that fine powder snow can often get into the airbox through the headlight adjuster on the Polaris IQ chassis models, especially the RMK models in the deep snow that was so common in the West this past season. We have had some questions regarding this, and have seen the problem ourselves. The Polaris gurus at Starting Line Products have put together a pre-filter that fastens to the hood in this area with Velcro so that you can still get to it and adjust the headlight, if need be.
A dealer out of Colorado indicated they had a couple of customers who would trailer their sleds (2005 RMK 900s) on open trailers without covers that got so much road salt and sand in their air boxes that it got into the motor and damaged it (remember, the 2005 RMK 900 didn’t have a headlight seal to start with). Therefore, it might be good that if you are going to trailer your sleds on an open trailer to make sure and cover them to eliminate any chance of road grime getting into places it should not be and damaging parts. This may seem logical to most of us, but we still see a lot of people trailering sleds without covers. I don’t know about you, but it really makes us sick to see a new sled covered with road grime or mud on the snow or trailer.
