Was spring riding last june and it was a perfect day outside so we decided not to cover the sleds. had about an 25 mile ride on a dirt road heading into survayor creek in western montana. when we got up to the snow our sleds were caked in dust not thinking much of it we rode. ran amazing over half of the day then i noticed i started loosing RPM's. my 2009 D8 always ran around 8000 (which id like to get 8200) but i seen it was going down to 7800....7700...7600 and wouldnt pull worth ****. the guys we were riding with figured it was the altitude compensator because i didnt loose that much RPMS. the PTO cylinder had alot of carbon build up on the spark plugs. so with the thought of the compensator bad i road it easy the rest of the day lol. even dropped down into kid lake and messed around with only a slight hick up here and there with a nice blubber climbing out of the lake lol. took it into the shop and they said they found "sand" in the engine. so its like the dirt and dust from the long ride on the sled bed into the snow settled in there and the vibrations from us riding must have shooken some past the filters and everything?? this i dont no. would it be worth replacing the air intake to something with a little more filtration?? feed back would be appreciated.
