Spark Plugs
Spark Plug Inspection
Spark plug condition is indicative of engine operation. The spark plug
firing end condition should be read after the engine has been warmed up
and the vehicle has been driven at higher speeds. Immediately check the
spark plug for correct color.
CAUTION! A hot exhaust system and engine can cause burns. Wear
protective gloves when removing a spark plug for inspection.
1. Remove the left side panel.
2. Remove the spark plug cap.
3. Using the special wrench provided in the tool pouch, rotate the
spark plug counter-clockwise to remove.
4. Reverse the procedure for spark plug installation. Torque to specifi-
cation.
5. Reinstall the spark plug cap.
Spark Plug Condition
Normal Plug
The normal insulator tip is gray, tan or light brown. There will be few
combustion deposits. The electrodes are not burned or eroded. This indi-
cates the proper type and heat range for the engine and the service.
Wet Fouled Plug
The wet fouled insulator tip is black. A damp oil film covers the firing
end. There may be a carbon layer over the entire nose. Generally, the
electrodes are not worn. General causes of fouling are excessive oil or
use of non-recommended injection oil.
