Inspection
The spark plug is an important engine compo-
nent 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 ATV that is being ridden normally.
Do not attempt to diagnose such problems
yourself.
