Engine break-in
There is never a more important
period in the life of your engine than
the period between 0 and 1600 km
(1000 mi). For this reason, you should
read the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts
in the engine wear and polish them-
selves to the correct operating clea-
rances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAU17050
0~1000 km (0~600 mi)
Avoid prolonged operation above 1/3
throttle.
1000~1600 km (600~1000 mi)
Avoid prolonged operation above 1/2
throttle.
ECA11660
CAUTION:
After 1000 km (600 mi) of operation,
be sure to replace the engine oil
and final transmission oil.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
ECA11650
CAUTION:
If any engine trouble should
occur during the engine break-
in period, immediately have a
Yamaha dealer check the vehi-
cle.
EAU17212
Parking
When parking, stop the engine, and
then remove the key from the main
switch.

WARNING
Since the engine and exhaust
system can become very hot,
park in a place where pedes-
trians or children are not likely
to touch them.
Do not park on a slope or on
soft ground, otherwise the
vehicle may overturn.
ECA10380
CAUTION:
Never park in an area where there
are fire hazards such as grass or
other flammable materials.

Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. The most important
points of inspection, adjustment, and
lubrication are explained on the follo-
wing pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, DEPENDING
ON THE WEATHER, TERRAIN, GEO-
GRAPHICAL LOCATION, AND INDIVI-
DUAL USE, THE MAINTENANCE
INTERVALS MAY NEED TO BE
SHORTENED.

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)

Yamaha dealer check and repair the
scooter. In addition, the final trans-
mission oil must be changed as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Start the engine, warm up the
final transmission oil by riding the
scooter for several minutes, and
then stop the engine.

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.

ECA10470
CAUTION:
If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.
If water has been used instead
of coolant, replace it with coo-
lant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the coo-
ling system will not be protec-
ted against frost and corrosion.
If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possi-
ble, otherwise the effective-
ness of the coolant will be
reduced.
