FOG THE ENGINE
1. Treat the fuel system with POLARIS Carbon Clean or other equivalent fuel
treatment. Follow the instructions on the container. Start the engine. Allow it
to idle for several minutes so the Carbon Clean reaches the injectors. Stop
the engine.
2. Remove the spark plugs and add 2-3 tablespoons of 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. 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 plugs. Torque to specification. See page 151.
4. Apply dielectric grease to the inside of each spark plug cap. Do not reinstall
the caps onto the plugs at this step.
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, fuel tank, fuel lines, and
injectors should be completely drained of gasoline.
7. Reinstall the spark plug caps to the spark plugs.
