Storage Tips
Fog the Engine
1. Treat the fuel system with Polaris Carbon Clean, following the
instructions on the can. Run the engine for several minutes so the
Carbon Clean reaches the injector. Turn the engine off.
2. Remove the spark plug and add 2-3 tablespoons of Premium 4
Synthetic 0W40 engine oil. To access the plug holes, use a section of
clear 1/4” hose and a small plastic squeeze bottle filled with the
pre-measured amount of oil.
NOTE: Do this carefully! If you miss the plug holes, oil will drain from
the spark plug cavities into the hole at the front of the cylinder
head, and appear to be an oil leak.
3. Reinstall the spark plug. Torque to 18 ft. lbs. (24 Nm).
4. Apply dielectric grease to the inside of the spark plug cap and
reinstall the cap onto the plug.
5. Turn the engine over several times. Oil will be forced in and around
the piston rings and ring lands, coating the cylinder with a protective
film of fresh oil.
6. If Polaris fuel system additive is not used, the fuel tank, fuel lines,
and injector should be completely drained of gasoline.
