Spark Plug Inspection<br />
Spark plug condition is indicative of engine operation. The spark plug<br />
firing end condition should be read after the engine is warmed up and<br />
the vehicle is driven at higher speeds. Immediately check the spark plug<br />
for correct color. See page 62.<br />
CAUTION! A hot exhaust system and engine can cause burns. Wear<br />
protective gloves when removing a spark plug for inspection.<br />
1. Remove the seat to access the engine compartment.<br />
2. Remove the spark plug cap. Using the spark plug wrench provided<br />
in the tool kit, remove the plug by rotating it counter-clockwise.<br />
3. Reverse the procedure for spark plug installation. Torque to specification.<br />
