Inspection
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
vehicle that is being ridden normally. Do not attempt to diagnose
such problem yourself. Instead, take the vehicle to 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.
