Engine oil and oil filter car-
tridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion. A slight tilt to the side can
result in a false reading.
2. Remove the rider seat. (See page
3-16.)
3. Start the engine, warm it up until
the engine oil has reached a nor-
mal temperature of 60 °C (140 °F),
let it continue to idle for ten sec-
onds, and then turn the engine off.TIPTo achieve the proper engine oil tem-
perature for an accurate oil level read-
ing, the engine must have firstcompletely cooled down, and then
warmed up again for several minutes to
normal operating temperature.
4. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the engine oil dipstick clean, insert
it back into the oil filler hole (with-
out screwing it in), and then re-
move it again to check the oil level.TIPThe engine oil should be between theminimum and maximum level marks.
5. If the engine oil is at or below the
minimum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.
TIPWhen adding oil, be careful not to over-
fill the engine oil tank; the oil level rises
faster starting from the half level portionon the dipstick.
6. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
7. Install the rider seat.

The tire air pressure should be checked
and, if necessary, adjusted before each
ride.
WARNING
EWA10501
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or death from loss of
control.

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 ad-
justed in accordance with the
riding speed and with the total
weight of rider, passenger, car-
go, and accessories approvedfor this model.
WARNING
EWA10511
Never overload your vehicle. Opera-
tion of an overloaded vehicle couldcause an accident.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.
TIPThe tire tread depth limits may differ
from country to country. Always complywith the local regulations.

6 Tire information
This motorcycle is equipped with cast
wheels and tubeless tires.
WARNING
EWA10461
The front and rear tires should be of
the same make and design, other-
wise the handling characteristics of
the vehicle may be different, whichcould lead to an accident.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha Motor Co., Ltd.
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.
EAU21960
Cast wheels To maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.

The wheel rims should be checked
for cracks, bends or warpage be-
fore each ride. If any damage is
found, have a Yamaha dealer re-
place 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 han-
dling characteristics, and a short-
ened 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 characteris-
tics.

Clutch lever Since this model is equipped with a hy-
draulic clutch, adjusting the clutch lever
free play is not needed. However, it is
necessary to check the clutch fluid level
and check the hydraulic system for
leakage before each ride. (See page
6-16.) If the clutch lever free play does
become excessive, and shifting be-
comes rough or clutch slippage occurs,
causing poor acceleration, there may
be air in the clutch system. If there is air
in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the motorcycle.
EAU22272
Adjusting the rear brake light
switch The rear brake light, which is activated
by the brake pedal, should come on just
before braking takes effect. If neces-
sary, adjust the rear brake light switch
as follows.
Turn the rear brake light switch adjust-
ing nut while holding the rear brake light
switch in place. To make the brake light
come on earlier, turn the adjusting nut
in direction (a). To make the brake light
come on later, turn the adjusting nut in
direction (b).

Insufficient brake or clutch fluid may al-
low air to enter the brake or clutch sys-
tems, possibly causing them to become
ineffective.
TIPThe rear brake fluid reservoir is locatedunder the rider seat. (See page 3-16.)
Before riding, check that the brake and
clutch fluids are above the minimum
level marks and replenish if necessary.
A low brake or clutch fluid level may in-
dicate brake or clutch system leakage
and/or worn brake pads. If the brake or
clutch levels are low, be sure to check
the brake or clutch systems for leakage
and the brake pads for wear.

6Observe these precautions:


When checking the brake and
clutch fluid levels, make sure that
the top of each reservoir is level.


Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.


Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.


Be careful that water does not en-
ter the brake or clutch fluid reser-
voir when refilling. Water will
significantly lower the boiling point
of the fluid and may result in vapor
lock.


Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.


As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
EAU22751
Changing the brake and
clutch fluids Have a Yamaha dealer change the
brake and clutch fluids at the intervals
specified in the TIP after the periodic
maintenance and lubrication chart. In
addition, have the oil seals of the brake
and clutch master cylinders and cali-
pers as well as the brake and clutch
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.

Oil seals: Replace every two
years.


Brake and clutch hoses: Replace
every four years.
