SPARK PLUG
1. Wipe and clean the dust and mud around the
spark plug mounting to avoid falling inside the
cylinder.
2. Pullout the suppressor cap from spark plug.
Remove the spark plug using a plug spanner.
A spark plug with heavy carbon deposits will not
produce strong sparks. Hence, only if necessary,
remove 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 a
new one.
Inspect the spark plug gap with a wire gauge / feeler
gauge. Readjust the spark plug gap to 0.9 ~ 1.0 mm
if the gap is found more.
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.
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 tighten the new spark plug by hand till
the end, using plug spanner tighten by 1/4 turn. Then
loosen the plug by 1/8 turn and re-tighten using plug
spanner.
