MAINTENANCE
A
B
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.
0.9 ~ 1.0 mm

Caution
Always use only recommended make and type of
spark plug. Replace spark plug every 12000 km.
Cover the spark plug hole with 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 and then loose and again re-tight the spark
plug by 1/8 of rotation after sealing by using only the
hand tool.
