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 accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plug can re -
veal the condition of the engine.
Check the spark plug
1. Remove cover
2. Remove the spark plug cap
3. Remove the spark plug as shown,
with the spark plug wrench inclu -
ded in the owner’s tool kit.
4. Check that the porcelain insulator
(1) around the center electrode of
the spark plug is a medium-to-light
tan (the ideal color when the vehicle
is ridden normally).

CAUTION
If the spark plug shows a distinctly diffe -
rent color, the engine could be operating
improperly. Do not attempt to diagnose
such problems yourself. Instead,
have a dealer check the vehicle.
5. Check the spark plug for electrode
corrosion and excessive carbon or
other deposits, and replace it if ne-
cessary.
