New to the forum and just bought my first atv from a local dealer. Checking it over at the dealer it sounded fine, probably didnt let it warm up as long as i should have. Got it home and went for my first ride and noticed a knock in the motor at idle when i was pulling it in the garage, sounded like a rod knock. Ive seen alot on here about polaris engines being noisey, is it normal? Also had the coolant overflow topped off before i left the dealer and its back down to the low level it was while it wad there. Any help would be appreciated.
