Final transmission oil
The final transmission case must be
checked for oil leakage before each
ride. If any leakage is found, have a
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 it up by
riding the scooter for several
minutes, and then stop the engi-
ne.
2. Place the scooter on the centers-
tand.
3. Place an oil pan under the final
transmission case to collect the
used oil.

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.
EAUS1270
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 checked
on a cold engine since the level
varies with engine temperature.
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.
1. Maximum level
2. Minimum level
2. Check the coolant level through

3. If the coolant is at or below theminimum 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 possible,
otherwise the effectiveness of
the coolant will be reduced.

1. Throttle cable free play
The throttle cable free play should
measure 3 ~ 5 mm (0,11 ~ 0,19 in) at
the throttle grip. Periodically check
the throttle cable free play and, if
necessary, adjust it as follows.
NOTE:
The engine idling speed must be
correctly adjusted before checking
and adjusting the throttle cable free
play.
1. Remove cowling A (See page 6-5).2. Loosen the locknut.
3. To increase the throttle cable free
play, turn the adjusting nut in
direction (a). To decrease the
throttle cable free play, turn the
adjusting nut in direction (b).
4. Tighten the locknut.
5. Install the cowling.

Valve clearance
The valve clearance changes with
use, resulting in improper air-fuel mix-
ture and/or engine noise. To prevent
this from occurring, the valve clearan-
ce must be adjusted by a Yamaha
dealer at the intervals specified in the
periodic maintenance and lubrication
chart.

Tires
To maximize the performance, durabi-
lity, and safe operation of your

sWARNING
The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperatu-
re 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 appro-
ved for this model.
EWA10450
s sWARNING
Because loading has an enormous
impact on the handling, braking,
performance and safety characte-
ristics of your vehicle, you should
keep the following precautions in
mind.
NEVER OVERLOAD THE VEHI-
CLE! Operation of an overloa-
ded vehicle 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 pac-
ked 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 suspension and tire
air pressure with regard to the
load.
Check the tire condition and air
pressure before each ride.
1. Tire tread depth
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 Yama-
ha dealer replace the tire immediately.
NOTE: The tire tread depth limits may differ
from country to country. Always
comply with the local regulations.
Minimum tire tread depth (front
and rear): 1.6 mm (0.06 in)
Tire air pressure (measured on
cold tires):Up to 90 kg (198 lb):Front:190kPa (27,02 psi) (1,9kgf/cm

WARNING
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
vehicle with excessively worn
tires decreases riding stability
and can lead to loss of control.
The replacement of all wheel
and brake related parts, inclu-
ding the tires, should be left to
a Yamaha dealer, who has the
necessary professional know-
ledge and experience.
EAU21960
Cast wheels
To maximize the performance, durabi-
lity, and safe operation of your
motorcycle, note the following points
regarding the specified wheels.
The wheel rims should be chec-
ked 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 crac-
ked 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 characte-
ristics.

Front and rear brake lever
free play
There should be no free play at the
brake lever ends. If there is free play,
have a Yamaha dealer inspect the
brake system.

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.

Check each front brake pad for
damage and measure the lining thick-
ness. If a brake pad is damaged or if
the lining thickness is less than 4,0
mm (0,16 in), have a Yamaha dealer
replace the brake pads as a set.
EAU22520
Rear brake pads
The rear brake is provided with a
check plug, which, if it is removed,
allows you to check the brake pad
wear without disassembling the bra-
ke. To check the brake pad wear,
check the position of the wear indica-
tor while applying the brake. If a bra-
ke pad has worn to the point that thewear indicator almost touches the
brake disc, have a Yamaha dealer
replace the brake pads as a set.
EAU22580
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 bra-
ke 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.
Observe these precautions:
When checking the fluid level,
make sure that the top of the bra-
ke fluid reservoir is level.
Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.

Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
Brake fluid may deteriorate pain-
ted 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.
EAUM1360
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the brake
hose replaced every four years or
whenever it is damaged or leaking.
EAU23111
Checking and lubricating the
throttle grip and cable
The operation of the throttle grip
should be checked before each ride.
In addition, the cable should be lubri-
cated at the intervals specified in the
periodic maintenance chart.
EAU23170
Lubricating the front and
rear brake levers
The pivoting points of the front and
rear brake levers must be lubricated
at the intervals specified in the perio-
dic maintenance and lubrication
chart.
EAU23211
Checking and lubricating the
centerstand and sidestand
The operation of the centerstand and
sidestand should be checked before
each ride, and the pivots and metal-
to-metal contact surfaces should be
lubricated if necessary.
Recommended lubricant:
Lithium-soap-based grease (all-
purpose grease)
