I have been having issues with my sled bogging when the track is under load in deep snow conditions or just when the sled becomes covered in snow. It seems to run very rich for a while afterwards. I have added flowrites to the airbox and run a dj clutch kit which is inspected regularly. I have also checked the dpm solenoid for movenment but noticed there appears to be a hose missing off of the top of the dpm. Just wondering if that nipple is supposed to be open and if not could that be causing the problems listed above??
