Checking the spark plug
The spark plug is an important engine component,
which is easy to check. Since heat and deposits
will cause any spark plug to slowly erode,the spark
plug should be removed and checked. In addition,
the condition of the spark plug can reveal the con-
dition of the engine.
To remove the spark plug
1. Remove the spark plug cap.
2. Remove the spark plug with the spark plug
wrench.
To check the spark plug
1. Check that the porcelain insulator around the
center electrode of the spark plug is a medium-
to-light tan (the ideal color when the ATV is ridden
normally).
N O T E
If the spark plug shows a distinctly different color,
the engine could be operating improperly. Do not
attempt to diagnose such problems yourself.
Instead, have a dealer check the ATV.
2. Check the spark plug for electrode erosion and
excessive carbon or other deposits, and replace it
if necessary.
To install the spark plug
1. Measure the spark plug gap with a wire thick-
ness gauge and, if necessary, adjust the gap to
specification.
