WARNING
EWA10270


Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.


Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.


Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible lossof control.

Starting and warming up a
cold engine 1. Turn the key to “ON”.
2. Shift the transmission into the neu-
tral position.NOTE:
When the transmission is in the neutral
position, the neutral indicator light
should be on, otherwise have a
Yamaha dealer check the electrical cir-cuit.
3. Place the vehicle on the center-
stand.
WARNING
EWA14200
Before starting the engine, make
sure the transmission is in neutral
and that the vehicle is placed on thecenterstand.
4. Turn the starter (choke) on and
completely close the throttle. (See
page 3-7.)
5. Start the engine by pushing the
start switch or by pushing the kick-
starter lever down.
NOTE:If the engine fails to start by pushing the
start switch, release the switch, wait a
few seconds, and then try again. Each
starting attempt should be as short as
possible to preserve the battery. Do not
crank the engine more than 10 seconds
on any one attempt. If the engine does
not start with the starter motor, try usingthe kickstarter.CAUTION:
ECA15170
The coolant temperature warning
light should come on when the key
is turned to “ON”, and then go off af-
ter a few seconds. If the coolant tem-
perature warning light comes on
after starting, immediately stop the
engine, and have a Yamaha dealercheck the electrical circuit.
6. After starting the engine, move the
starter (choke) back halfway.

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

If you are not familiar with mainte-
nance work, have a Yamaha dealerdo it for you.

use only YAMAHA GENUINE
COLANT. Using coolan other than
recommended, could cause damage
to oil seal and o-rings, as whell
as to the cooling system.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not be sufficiently cooled and the cool-
ing system will not be protected
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 ofthe coolant will be reduced.WARNING

Tires To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, 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.
WARNING
EWA10500


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
EWA10530
Proper loading of your motorcycle is
important for several characteristics
of your motorcycle; such as han-
dling, braking, performance and
safety. Do not carry loosely packed
items that can shift. Securely pack
your heaviest items close to the cen-
ter of the motorcycle, and distribute
the weight evenly from side to side.
Check the condition and pressure of
your tires. NEVER OVERLOAD
YOUR MOTORCYCLE. Make surethe total weight of the cargo, rider,
passenger, and accessories (fairing,
saddlebags, etc. if approved for this
model) does not exceed the maxi-
mum load of the motorcycle. Opera-
tion of an overloaded motorcycle
could cause tire damage, an acci-
dent, or even injury.
Tire inspection
The tires must be checked before each
ride. If the tire shows crosswise lines
(minimum tread depth), if the tire has a
nail or glass fragments in it, or if the
sidewall is cracked, have a Yamaha
dealer replace the tire immediately.
NOTE:
The tire tread depth limits may differ
from country to country. Always complywith the local regulations.
Tire information
This motorcycle is equipped with tube
tires.
WARNING
EWA10460


The front and rear tires should
be of the same make and de-
sign, otherwise the handling
characteristics of the vehicle
cannot be guaranteed.

WARNING
EWA10560


It is dangerous to ride with a
worn-out tire. When a tire tread
begins to show crosswise lines,
have a Yamaha dealer replace
the tire immediately.


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.


It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tube very carefully and replace it as
soon as possible with a high-
quality product.
EAU21940
Spoke wheels To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points
regarding the specified wheels.

The wheel rims should be checked
for cracks, bends or warpage, and
the spokes for looseness or dam-
age before each ride. If any dam-
age 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 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.

Checking the brake lever free
play There should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.
WARNING
EWA14210
A soft or spongy feeling in the brake
lever can indicate the presence of air
in the hydraulic system. If there is air
in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the motorcycle. Air in
the hydraulic system will diminish
the braking performance, which may
result in loss of control and an acci-dent.
EAU22181
Adjusting the brake pedal free
play The brake pedal free play should mea-
sure 25.0–35.0 mm (0.98–1.38 in) at
the brake pedal end as shown. Period-
ically check the brake pedal free play
and, if necessary, adjust it as follows.
To increase the brake pedal free play,
turn the adjusting nut in direction (a). To
decrease the brake pedal free play,
turn the adjusting nut in direction (b).
WARNING
EWA10680


After adjusting the drive chain
slack or removing and installing
the rear wheel, always check the
brake pedal free play.


If proper adjustment cannot be
obtained as described, have a
Yamaha dealer make this ad-
justment.


After adjusting the brake pedal
free play, check the operation ofthe brake light.

ing nut at each end of the
swingarm in direction (b), and then
push the rear wheel forward.
NOTE:Using the alignment marks on each
side of the swingarm, make sure that
both chain pullers are in the same posi-tion for proper wheel alignment.CAUTION:

Improper drive chain slack will over-
load the engine as well as other vital
parts of the motorcycle and can leadto chain slippage or breakage. To
prevent this from occurring, keep
the drive chain slack within the
specified limits.
4. Tighten both locknuts, and then
tighten the axle nut and brake
torque rod nut to their specified
torques.NOTE:When tightening the axle nut, hold the
wheel axle with a wrench to keep it fromturning.
5. Adjust the brake pedal free play.

Cleaning and lubricating the
drive chain The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly wear
out, especially when riding in dusty or
wet areas. Service the drive chain as
follows.CAUTION:
ECA10581
The drive chain must be lubricated
after washing the motorcycle andriding in the rain.
1. Remove all dirt and mud from the
drive chain with a brush or cloth.NOTE:For a thorough cleaning, have a
Yamaha dealer remove the drive chainand soak it in solvent.
