Spark Plug - KYMCO MXU 270i EURO Manual

SPARK PLUG

The spark plug is an important engine component and is easy
to inspect. The condition of the spark plug can indicate the
condition or the engine and how well it is operating.
A light brown insulator indicates that the sparkplug is correct.
A very white center electrode porcelain color could indicate an
intake air leak or a fuel injection problem. Do not attempt to
diagnose such problems yourself. Instead, take your ATV to
your KYMCO dealer.
Before inspecting a spark plug, clean the area around the spark
plug to prevent dirt from the entering the engine when
removing or installing the spark plug.
