6.1 Spark plug inspection
The spark plug is important engine components, which should be checked
periodically.
Standard Spark Plug: F6RTC
Spark Plug Gap: 0.7-0.8mm
TIP:
The spark plug gap should be measured with a wire thickness gauge
and, If necessary, adjusted to specification.
Spark Plug Torque: 28 N.m
5. Install the spark plug.
TIP:
If a torque wrench is not available when installing a spark plug, a good
estimate of the correct torque is 1/4-1/2 turn past finger tight. However, the
spark plug should be tightened to the specified torque as soon as possible.
6. Install the spark plug cap and spark plug cover.
