SPARK PLUG
1. Clean the dust and mud around the spark plug
mounting to avoid falling inside the cylinder.
2. Pullout the suppressor cap from the spark plug.
3. Using the spark plug spanner, remove the spark
plug.
A spark plug with heavy carbon deposits will not
produce strong sparks. Hence, only if necessary,
clean the carbon deposits from the spark plug with a
small wire brush or spark plug cleaning tool.
Inspect the spark plug electrodes (A) and (B) for any
corrosion. If found any replace the spark plug with
new.
Inspect the spark plug gap visually (0.9 ~ 1.0 mm). If
found more, replace the spark plug with a new one.
After cleaning and inspecting the gap, reinstall
the spark plug and tighten by hand to avoid cross
threading. Finally tighten using spark plug spanner.
Do not over tight or cross thread the spark plug. After
reassembling the plug fix back the suppressor cap
and ensure its proper fitment.
Always use only the recommended make and type of
spark plug. Replace the spark plug every 12000 km.
Cover the spark plug hole with a clean cloth when the
plug is removed to prevent dust / water entry.
It is advisable to tight the new spark plug by hand till the
end and then loose. Again re-tight the spark plug by 1/8
of rotation after sealing by using only the hand tool.
Since the hook type spark plug is used, it is not advised
to adjust the plug electrodes as it may damage the
electrodes.
