Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1000 km (600 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances. Dur-
ing this period, prolonged full-throttle
operation or any condition that might
result in engine overheating must be
avoided. Fuel consumption, tips for reducing
Engine break-in
EAU16820
Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the following
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 traf-
fic lights or at railroad crossings).
EAU16951
0 ~ 150 km (0 ~ 90 mi)
Avoid prolonged operation above 1/3
throttle.
After every hour of operation, stop the
engine, and then let it cool for five to
ten minutes.Vary the engine speed from time to time.
Do not operate the engine at one set
throttle position.
150 ~ 500 km (90 ~ 300 mi)
Avoid prolonged operation above 1/2
throttle.
Rev the engine freely through the gears,
but do not use full throttle at any time.
500 ~ 1000 km (300 ~ 600 mi)
Avoid prolonged operation above 3/4
throttle.
NOTICE:
After 1000 km (600
mi) of operation, the engine oil must
be changed and the oil strainer
cleaned.
[ECA10351]
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the speed occasionally.
ECA10270
NOTICEIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

WARNING
● ●● ●
●
Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them and be burned.
● ●● ●
●
Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn, increasing the risk
of a fuel leak and fire.
● ●● ●
●
Do not park near grass or other
flammable materials which
might catch fire.

Valve clearance
Tires
EAU21401
Valve clearanceThe valve clearance changes with use,
resulting in improper air-fuel mixture and/
or engine noise. To prevent this from
occurring, the valve clearance must be
adjusted by a Yamaha dealer at the in-
tervals specified in the periodic mainte-
nance and lubrication chart.
EAUT2141
TiresTo maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.
EWA10501
WARNING
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or death from loss of con-
trol.

8The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).

WARNING
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the area,
including pilot lights from water heat-
ers or furnaces. Gasoline or gasoline
vapors can ignite or explode, caus-
ing severe injury or property damage.
EAU25881
TroubleshootingAlthough Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur dur-
ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting charts rep-
resent quick and easy procedures for
checking these vital systems yourself.
However, should your scooter require any
repair, take it to a Yamaha dealer, whose
skilled technicians have the necessary
tools, experience, and know-how to ser-
vice the scooter properly.
Use only genuine Yamaha replacement
parts. Imitation par ts may look like
Yamaha parts, but they are often infe-
rior, have a shorter service life and can
lead to expensive repair bills. Troubleshooting

luted mild detergent with water
may be used. Be sure to rinse off
any detergent residue using
plenty of water, as it is harmful
to plastic parts.
● ●● ●
●
Do not use any harsh chemical
products on plastic parts. Be sure
to avoid using cloths or sponges
which have been in contact with
strong or abrasive cleaning prod-
ucts, solvent or thinner, fuel
(gasoline), rust removers or in-
hibitors, brake fluid, antifreeze or
electrolyte.
● ●● ●
●
Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar-
eas: seals (of wheel and
swingarm bearings, fork and
brakes), electric components
(couplers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
● ●● ●
●
For scooters equipped with a
windshield: Do not use strongcleaners or hard sponges as they
will cause dulling or scratching.
Some cleaning compounds for
plastic may leave scratches on
the windshield. Test the product
on a small hidden part of the
windshield to make sure that it
does not leave any marks. If the
windshield is scratched, use a
quality plastic polishing com-
pound after washing.
After normal use
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge, and
then rinse thoroughly with clean water.
Use a toothbrush or bottlebrush for hard-
to-reach areas. Stubborn dirt and insects
will come off more easily if the area is
covered with a wet cloth for a few min-
utes before cleaning.After riding in the rain, near the sea oron salt-sprayed roads
Since sea salt or salt sprayed on the
roads during winter are extremely corro-sive in combination with water, carry out
the following steps after each ride in the
rain, near the sea or on salt-sprayed
roads.
TIP
Salt sprayed on roads in the winter may
remain well into spring.1. Clean the scooter with cold water
and a mild detergent after the en-
gine has cooled down.
NOTICE:
Do
not use warm water since it in-
creases the corrosive action of
the salt.
[ECA10791]
2. Apply a corrosion protection spray
on all metal, including chrome- and
nickel-plated, surfaces to prevent
corrosion.
After cleaning
1. Dry the scooter with a chamois or
an absorbing cloth.
2. Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
