Checking the spark plugThe 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.
To remove the spark plug
1. Remove panel A. (See page 6-5.)
2. Remove the spark plug cap.ZAUM00**

1. Spark plug wrench
Spark plug, checking
3. Remove the spark plug as shown,
with a spark plug wrench available
at a Yamaha dealer.
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 vehicle is
ridden normally).
TIP
If the spark plug shows a distinctly dif-
ferent color, the engine could be operat-
ing improperly. Do not attempt to diag-
nose such problems yourself. Instead,
have a Yamaha dealer check the vehicle.2. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if nec-
essary.Specified spark plug:
