Checking the spark plugs The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal col-
or when the motorcycle is ridden nor-
mally), and all spark plugs installed inthe engine should have the same color.
If any spark plug shows a distinctly dif-
ferent color, the engine could be defec-
tive. Do not attempt to diagnose such
problems yourself. Instead, have a
Yamaha dealer check the motorcycle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.
Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification.
After removal
Before installation
a. Spark plug gap
Specified spark plug:
CR9E (NGK) or
U27ESR-N (DENSO)
Spark plug gap:
0.7–0.8 mm

CAUTION:@ l
Always keep the battery
charged. Storing a discharged
battery can cause permanent
battery damage.
l
To charge a sealed-type (MF)
battery, a special (constant-
voltage) battery charger is re-
quired. Using a conventional
battery charger will damage the
battery. If you do not have ac-
cess to a sealed-type (MF) bat-
tery charger, have a Yamaha
dealer charge your battery.
