Inspect spark plug
Every 2 000 km (1 200 miles, 6 months)
Heat Range
1) Remove the spark plug. Refer to “Spark Plug
Removal and Installation in Section 1H (Page 1H-
3)”.
2) Check spark plug heat range by observing electrode
color.
If it appears white or glazed, replace the spark plug
with colder type one.
Heat range
3) After finishing the spark plug inspection, reinstall the
removed parts.
Tightening torque
Spark plug: 11 N·m (1.1 kgf-m, 8.0 lb-ft)
Carbon Deposits
1) Remove the spark plug. Refer to “Spark Plug
Removal and Installation in Section 1H (Page 1H-
3)”.
2) Check carbon deposits on the spark plug.
If carbon is deposited, remove it using a spark plug
cleaner machine.
3) After finishing the spark plug inspection, reinstall the
removed parts.
Spark Plug Gap
1) Remove the spark plug. Refer to “Spark Plug
Removal and Installation in Section 1H (Page 1H-
3)”.
2) Measure the spark plug gap using the thickness
gauge.
Adjust the spark plug gap if necessary.
Special tool
: 09900–20803 (Thickness gauge)
Spark plug gap
0.7 – 0.8 mm (0.028 – 0.030 in)
3) After finishing the spark plug inspection, reinstall the
removed parts.
Electrodes Condition
1) Remove the spark plug. Refer to “Spark Plug
Removal and Installation in Section 1H (Page 1H-
3)”.
2) Check to see the worn or burnt condition of the
electrodes.
If it is extremely worn or burnt, replace the spark
plug. And also replace the plug if it has a broken
insulator, or damaged thread.
3) After finishing the spark plug inspection, reinstall the
removed parts.
CAUTION
!
Check the thread size and reach when
replacing the spark plug. If the reach is too
short, carbon will be deposited on the screw
portion of the spark plug hole and engine
damage may result.
