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 accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
To remove the spark plug
1. Open the seat. (See page 3-13.)
2. Remove the storage compart-
ment under the seat by removing
the bolts.
1. Rear storage compartment
2. Bolts1. Spark plug cap
3. Remove the spark plug cap.
1. Spark plug wrench
4. Remove the spark plug as
shown, with the spark plug
wrench included in the owner’s
tool kit.To check the spark plug
1. Check that the porcelain insula-
tor around the center electrode of
the spark plug is a medium-to-
light tan (the ideal color when the
motorcycle is ridden normally).
NOTE:
If the spark plug shows a distinctly
different color, the engine could be
defective. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the motorcy-
cle.
2. Check the spark plug for electro-
de erosion and excessive carbon
or other deposits, and replace it if
necessary.

To install the spark plug
1. Spark plug gap
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to spe-
cification.
2. Clean the surface of the spark
plug gasket and its mating surfa-
ce, and then wipe off any grime
from the spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then
tighten it to the specified torque.
NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4~1/2 turn past finger tight. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
4. Install the spark plug cap.
NOTE:
Make sure the spark plug wire is fas-
tened in the clamp as shown.
5. Install the storage compartment
by installing the bolts.
6. Close the seat.
EAUM1550
Engine oil
The engine oil level should be chec-
ked before each ride. In addition, the
oil must be changed at the intervals
specified in the periodic maintenance
and lubrication chart and when the
service indicator light comes on.
To check the engine oil level
1. Place the scooter on the centers-
tand.
NOTE:
Make sure that the scooter is positio-
ned straight up when checking the oil
level. A slight tilt to the side can result
in a false reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
Tightening torque:
Spark plug:
17.5 Nm (1.75 m•kgf, 12.7 ft•lbf)
Spark plug gap:
0.8~0.9 mm (0.031~0.035 in)

WARNING
Make sure that no foreign
material enters the final trans-
mission case.
Make sure that no oil gets on
the tire or wheel.
7. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.
EAU20070
Coolant
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUS1272
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
NOTE:
The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
Make sure that the vehicle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
2. Check the coolant level through
the check window.
1. Maximum level mark
2. Minimum level mark
3. Coolant level window
NOTE:
The coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below the
minimum level mark, remove the
right floorboard mat by pulling it
up.
4. Open the reservoir cap, and then
add coolant to the maximum
level mark.
Recommended final transmission
oil:
See page 8-1.
Oil quantity:
0.25 L (0.26 US qt) (0.22 Imp.qt)
