I did a oil-change on my sled a few weeks ago. God, what a project. First you have to take off 6 hex screws on the bottom of the sled and remove a pan, then remove the oil bolt and drain the oil. Then you have to take the side panel off (more screws) and drain the oil from the oil tank. Then you have to remove like half the shit in the motor to get at the oil filter way down inside.
