SPARK PLUG
Neglecting the spark plug maintenance eventually leads to
difficult starting and poor performance. If the spark plug is used for a
long time, the electrode gradually burns away and carbon builds up
along the inside part. In accordance with the periodic table, the plug
should be removed for inspection, cleaning and to reset the gap.
Carbon deposits on the spark plug will prevent good sparking
and cause misfiring. Clean the deposits off periodically.
If the center electrode is fairly worn down, the plug should be
replaced and the plug gap set to the specified gap using a
thickness gauge.
Thickness gauge
Spark plug gap：0.6-0.7 mm (0.024-0.028 inch)
Check the spark plug for burnt condition. If abnormal replace the spark
plug as indicated in the chart.

BPR7HS E8RTC
If the standard plug is apt to get wet,
replace with the plug.

If the standard plug is apt to
overheat, replace with the plug.
Tighten the spark plug to the specified torque.
Spark plug
Tightening torque:15-18N.m
NOTE:
To check the spark plug, first make sure that the fuel used is
unleaded gasoline, and if plug is either sooty with carbon or
burnt white, replace it.
Confirm the thread size and reach when replacing the plug.
FUEL LINE
Inspect at initially 1000 km (600 miles,2 months) and every
6000 km (4000 miles,12 months), replace every 4 years.
