Standard spark plug: C7HSA/NGK U22FS-U/DENSO
Spark plug inspection The spark plug is an important engine component and is easy to inspect. The condition of the spark plug can indicate the condition of the engine. The ideal color on the white insulator around the center electrode is a medium-to-light tan color for a motorcycle that is being ridden normally. You should periodically remove and inspect the spark plug because heat and deposits will cause the spark plug to slowly break down and erode. If electrode erosion becomes excessive, or if carbon and other deposits are excessive, you should replace the spark plug with the specified plug.
1 Spark plug gap
48
Spark plug gap: 0. 6 ~ 0. 7 mm Spark plug torque: 12. 5 Nm (1. 25 m·kg)
Before installing the spark plug, measure the electrode gap with a wire thickness gauge; adjust the gap to specification as necessary. When installing the plug, always clean the gasket surface and use a new gasket. Wipe off any grime from the threads and tighten the spark plug to the specified torque.
EUU03801
NOTE: If a torque wrench is not available when you are installing a spark plug, a good estimate of the correct torque is 1/4 to 1/2 turn past finger tight. Have the spark plug torqued to the correct value as soon as possible with a torque wrench.
