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 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 with a wire gauge / feeler
gauge. Readjust the spark plug gap to 0.9 ~ 1.0 mm
if required.
After cleaning and adjusting 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
re assembling the spark plug ensure proper fitment
of suppressor cap.
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 .
