The spark plug is an important engine
component and is easy to inspect. The
condition of the spark plug can indicate
the condition of the engine. The ideal
color on the white insulator around the
center electrode is a medium-to-light tan
color for a scooter that is being ridden
normally. Do not attempt to diagnose any
problems yourself. Instead, take the
scooter
to
a
dealer.
You
should
periodically remove and inspect the spark
plug because heat and deposits will cause
the spark plug to slowly break down and
erode. If electrode erosion becomes
excessive, or if carbon and other deposits
are excessive, you should replace the
spark plug with the specified plug.

Before installing the spark plug, measure the
electrode gap with a wire thickness gauge; adjust
the gap to specification if necessary. Spark Plug
Gap: 0.6-0.7mm
When installing the
plug, always clean the
gasket surface and use
a new gasket. Wipe off
any grime from the
threads and tighten the
spark plug with your
fingers first, then later with a torque wrench.
