Answer:
First thing you do is treat the fuel in the tank to help stabilize it. Remove the air box, start the engine let run for a few minutes for the stabilized fuel to get through the system, then spray oil into the carbs or intake of injected sleds until engine is smoking good and turn engine off. You can spray the engine and exhaust with a water displacer like WD-40 when it cools to help prevent corrosion from sitting in the wetter summer air. Grease all grease points on the sled. Lift up the front of the sled until skis are off the ground and block up under the frame not the skis. Now lift the rear of the sled off the ground until track clears and block it up. Now there should be no weight on your suspension and ready for the wait until the snow flies again.
