Adjusting the valve clea-
rance
The 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 intervals specified in the periodic
maintenance and lubrication chart.

Tires
To maximize the performance,
durability, and safe operation of your
scooter, 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.
EW000082
•The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).
•The tire air pressure must be
adjusted in accordance with the
riding speed and with the total
weight of rider, passenger,
cargo, and accessories
approved for this model.

6 Tire inspection
The tires must be checked before each
ride. 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.
EW000077
Because loading has an enormous
impact on the handling, braking, per-
formance and safety characteristics of
your scooter, you should keep the
following precautions in mind.
•NEVER OVERLOAD THE SCOO-
TER! Operation of an overloaded
scooter may result in tire damage,
loss of control, or severe injury.
Make sure that the total weight of
rider, cargo, and accessories
does not exceed the specified
maximum load for the vehicle.
•Do not carry along loosely
packed items, which can shift
during a ride.
•Securely pack the heaviest items
close to the center of the scooter
and distribute the weight evenly
on both sides.
•Adjust the suspension and tire air
pressure with regard to the load.
•Check the tire condition and air
pressure before each ride.

•Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
scooter with excessively worn
tires decreases riding stability
and can lead to loss of control.
•The replacement of all wheel
and brake related parts,
including the tires, should be
left to a Yamaha dealer, who has
the necessary professional
knowledge and experience.

Cast wheels
To maximize the performance,
durability, and safe operation of your
scooter, note the following points
regarding the specified wheels.
•The wheel rims should be
checked for cracks, bends or
warpage before each ride. If any
damage is found, have a Yamaha
dealer replace the wheel. Do not
attempt even the smallest repair
to the wheel. A deformed or
cracked wheel must be replaced.
•The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse
handling characteristics, and a
shortened tire life.
•Ride at moderate speeds after
changing a tire since the tire sur-
face must first be "broken in" for it
to develop its optimal
characteristics.

Adjusting the front and rear
brake lever free play
The front and rear brake lever free play
should measure 2 — 5 mm as shown.
Periodically check the front and rear
brake lever free play and, if necessary,
have a Yamaha dealer adjust it.
EW000100
An incorrect brake lever free play
indicates a hazardous condition in
the brake system. Do not operate the
scooter until the brake system has
been checked or repaired by a
Yamaha dealer.

Checking the front and rear
brake pads
The front and rear brake pads must be
checked for wear at the intervals
specified in the periodic maintenance
and lubrication chart. To check the
brake pad wear, measure the lining
thickness. If the lining thickness is less
than 3.8 mm, have a Yamaha dealer
replace the brake pads as a set.

EAU04856
Checking the brake fluid
level
Insufficient brake fluid may allow air to
enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake fluid
level may indicate worn brake pads
and/or brake system leakage. If the
brake fluid level is low, be sure to check
the brake pads for wear and the brake
system for leakage.

6Observe these precautions:
•When checking the fluid level,
make sure that the top of the brake
fluid reservoir is level.
•Use only the recommended
quality brake fluid, otherwise the
rubber seals may deteriorate,
causing leakage and poor braking
performance.
Recommended brake fluid:
DOT 4
1. Minimum level mark
•Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
•Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will
significantly lower the boiling point
of the fluid and may result in vapor
lock.
•Brake fluid may deteriorate
painted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
•As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if the
brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
EAUM0008*
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and
lubrication chart. In addition, have the
brake hoses replaced every four years
or whenever they are damaged or
leaking.

Checking and lubricating the
cables
The operation of all control cables and
the condition of the cables should be
checked before each ride, and the cables
and cable ends should be lubricated if
necessary. If a cable is damaged or does
not move smoothly, have a Yamaha dea-
ler check or replace it.
Recommended lubricant:
Engine oil
EW000112
Damage to the outer sheath may
interfere with proper cable operation
and will cause the inner cable to rust.
Replace a damaged cable as soon
as possible to prevent unsafe con-
ditions.
WARNING

Checking and lubricating the
throttle grip and cable
The operation of the throttle grip should
be checked before each ride. In addi-
tion, the cable should be lubricated or
replaced at the intervals specified in the
periodic maintenance chart.

Lubricating the front and
rear brake levers
The pivoting points of the front and rear

6 To check the operation
1. Place the scooter on a level sur-
face and hold it in an upright po-
sition.
2. While applying the front brake,
push down hard on the
handlebars several times to check
if the front fork compresses and
rebounds smoothly.

Checking the steering
Worn or loose steering bearings may
cause danger. Therefore, the operation
of the steering must be checked as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Place a stand under the engine
to raise the front wheel off the
ground.
EW000115
Securely support the scooter so that
there is no danger of it falling over.
