SECTION 4 - MAINTENANCE
Spark plug
Remove the carbon deposits from the spark plug with a
small wire brush or a spark plug cleaning machine. After
cleaning (or when installing a new spark plug) readjust the
spark plug gap to specified limit by using a spark plug gap
thickness gauge. The spark plug should be replaced
periodically. Under normal usage, a spark plugs porcelain tip
should appear light brown or tan in color. If the spark plug
porcelain tip is very white or glazed appearing, then the spark
plug has been operating too hot. In such a situation, you
should replace the standard spark plug with a spark plug that
has a colder heat range (usually a higher number; consult
with your KYMCO dealer when selecting an alternate spark
plug).
Recommended spark plug
Spark plug type:
CHAMPION-P-RZ9HC
Spark plug gap
: 0.6 - 0.7 mm
Spark plug service & replacement:
1.
Remove the spark plug with a suitable spark plug socket
2.
Inspect the spark plug for cracks in the porcelain
insulator, damage to the main threads, and for worn,
fouled or carbonized ground electrode.
3.
If the spark plug has only been removed once it is
acceptable to reuse (removal and reinstallation more
than two times will compromise the sealing washer’s
ability to seal combustion chamber gases).
4.
Remove the carbon deposits from the spark plug with a
small wire brush or a spark plug cleaning machine. After
cleaning (or when installing a new spark plug), readjust
the spark plug gap to the specified limit by using a spark
plug gap thickness gauge.
5.
Reinstall the cleaned (or new) spark plug in the cylinder
head, and tighten securely to the specified torque.
Spark plug torque: 8 lb-ft (11.2 N-m)
An improper spark plug may have an incorrect fit or
heat range for your mtorcycle’s engine. This may
cause severe engine damage which will not be covered
under warranty. Never use a spark plug with an
improper heat range, as severe engine damage may
