Cleaning and Storage
Storage Tips
Fog the Engine
1. After stabilizing the fuel, remove the spark plug and add 2-3
tablespoons of engine oil. To access the plug hole, use a section of
clear 1/4" hose and a small plastic squeeze bottle filled with the pre-
measured amount of oil.
2. Reinstall the spark plug. Torque to specification.
3. Apply dielectric grease to the inside of each spark plug cap and
reinstall the caps onto the plugs.
4. Turn the engine over several times using electric start. Oil will be
forced in and around the piston rings and ring lands, coating the
cylinder with a protective film of fresh oil.
5. If fuel system additive is not used, the fuel tank, fuel lines, and
injectors should be completely drained of gasoline.
Inspect and Lubricate
Inspect all cables and lubricate all areas of the vehicle as recommended
in the Periodic Maintenance Chart beginning on page 92.
Battery Storage
See pages 128-129 for storage and charging procedures. Store the
battery in a cool, dry place.
Storage Area/Covers
Set the tire pressure and safely support the ATV with the tires slightly
off the ground. Be sure the storage area is well ventilated. Cover the
vehicle with a genuine POLARIS cover. Do not use plastic or coated
materials. They do not allow enough ventilation to prevent
condensation, and may promote corrosion and oxidation.
