The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpec-
tedly, even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid lea-
kage or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a tho-
rough visual inspection, to check the following points before each ride.
NOTE:
Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very
short time; and the added safety it assures is more than worth the time involved.

WARNING
●Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer
regarding any control or func-
tion that you do not thoroughly
understand.
●Never start the engine or ope-
rate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of cons-
ciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
●For safety, always start the
engine with the centerstand
down.

WARNING
●Before starting the engine,
check the function of the igni-
tion circuit cut-off system
according to the procedure
described on page 3-18.
●Never ride with the sidestand

Braking
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.
EWA10300
s s
WARNING
●Avoid braking hard or suddenly
(especially when leaning over
to one side), otherwise the sco-
oter may skid or overturn.
●Railroad crossings, streetcar
rails, iron plates on road cons-
truction sites, and manhole
covers become extremely slip-pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.
●Keep in mind that braking on a
wet road is much more difficult.
●Ride slowly down a hill, as bra-
king downhill can be very diffi-
cult.
EAU16820
Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
●Avoid high engine speeds during
acceleration.
●Avoid high engine speeds with no
load on the engine.
●Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cros-
sings).

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.
EAUM2010
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.

CAUTION:
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

Parking
When parking, stop the engine, and
then remove the key from the main

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.

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.

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.
EAUS1273
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.
NOTE:
The coolant should be between the
minimum and maximum level marks.
1. Maximum level mark
2. Minimum level mark
3. Coolant level window
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.

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 cooling system will
not be protected against frost

●If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possi-
