PRE-OPERATION CHECKS
EAU15593
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, 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
EWA11150
If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operating
the vehicle.

PERIODIC MAINTENANCE AND MINOR REPAIR
EAU17280
Safety is an obligation of the owner. Pe-
riodic inspection, adjustment and lubri-
cation will keep your vehicle in the
safest and most efficient condition pos-
sible. The most important points of in-
spection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, DEPENDING ON THE
WEATHER, TERRAIN, GEOGRAPHI-
CAL LOCATION, AND INDIVIDUAL
USE, THE MAINTENANCE INTER-
VALS MAY NEED TO BE SHORT-
ENED.
WARNING
EWA10320
If you are not familiar with mainte-
nance work, have a Yamaha dealer
do it for you.
WARNING
EWA10330
This scooter is designed for use on
paved roads only. If this scooter isoperated in abnormally dusty, mud-
dy or wet conditions, the air filter el-
ement should be cleaned or
replaced more frequently, otherwise
rapid engine wear may result. Con-
sult a Yamaha dealer for proper
maintenance intervals.

mileage-based maintenance, is performed instead.
From 50000 km (30000 mi), repeat the maintenance intervals starting from 10000 km (6000 mi).

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 color
when the vehicle is ridden normally),
and all spark plugs installed in the en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
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.
Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.
NOTE:
If a torque wrench is not available wheninstalling a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible.
Specified spark plug:
NGK/CR7E

Do not carry along loosely
packed items, which can shift
during a ride.
Securely pack the heaviest
items close to the center of the
vehicle and distribute the
weight evenly on both sides.
Adjust the tire air pressure with
regard to the load.
Check the tire condition and air
pressure before each ride.
Tire inspection
The tires must be checked before eachride. If the center tread depth reaches
the specified limit, if the tire has a nail or
glass fragments in it, or if the sidewall is
cracked, have a Yamaha dealer re-
place the tire immediately.
NOTE:
The tire tread depth limits may differ
from country to country. Always comply
with the local regulations.
Tire information
This model is equipped with tubeless
tires.
WARNING
EWA10470
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the vehi-
cle with excessively worn tires
decreases riding stability and
can lead to loss of control.
The replacement of all wheel
and brake related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience.

Checking and lubricating the
centerstand and sidestand
The operation of the centerstand and
sidestand should be checked before
each ride, and the pivots and met-
al-to-metal contact surfaces should be
lubricated if necessary.
WARNING

If the centerstand or sidestand does
not move up and down smoothly,
have a Yamaha dealer check or re-
pair it.

Checking the front fork
The condition and operation of the front
fork must be checked as follows at the
intervals specified in the periodic main-
tenance and lubrication chart.
To check the condition
WARNING
EWA10750
Securely support the vehicle so that
there is no danger of it falling over.
Check the inner tubes for scratches,
damage and excessive oil leakage.
To check the operation
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
2. While applying the front brake,
push down hard on the handlebars
several times to check if the front
fork compresses and rebounds
smoothly.
