1. Remove the spark plug cap.
2. Remove the spark plug with the spark plug wrench.
3. Visually inspect the spark plug. Replace with a new plug if the insulation is
cracked or chipped. Clean with a wire brush if the spark plug is reused.
4. Measure the spark plug gap with a feeler gauge. The normal value is:
0.7-0.8mm (0.028- 0.031in). Adjust the gap by carefully bending the electrode.
5. Carefully reinstall the spark plug by hand, to avoid cross-threading. A new
spark plug should be tightened 1/2 turn with a spanner. A used spark plug
should be tightened 1/8 to 1/4 turn with spanner.
6. Reinstall the spark plug cap.
Note
 The spark plug must be securely tightened or it could cause the spark
plug to heat up, enough to damage the engine.
 Never use a spark plug with an improper heat range.
