GENERAL MAINTENANCE
SPARK PLUG
Inspection & Replacement
The spark plug is an important engine component and is easy
to inspect. The condition the spark plug can indicate the condi-
tion of your UTV's engine.
For example, a very white center electrode porcelain color could
indicate an intake air leak or carburetion problem. Do not at-
tempt to diagnose such problems yourself. Instead, take your
UTV to a KYMCO dealer.
You should periodically remove and inspect the spark plug be-
cause heat and deposits will cause the spark plug to slowly
wear down and erode. If electrode deterioration becomes se-
vere, replace the spark plug with one of the proper type.

NOTE:Before installing the spark plug, measure the
electrode gap with a feeler gauge and adjust to specifi-
cation. When installing the spark plug, always clean the
gasket surface and use a new spark plug if the sealing
gasket is pressed flat. Always tighten the spark plug to the
specified torque.
