Fuel tank breather/overflow
hose
1. Fuel tank breather/overflow hose
2. Clamp
Before operating the motorcycle:
Check the fuel tank breather/
overflow hose connection.
Check the fuel tank breather/
overflow hose for cracks or dam-
age, and replace it if damaged.
Make sure that the end of the fuel
tank breather/overflow hose is not
blocked, and clean it if necessary.
Make sure that the end of the fuel
tank breather/overflow hose is
positioned inside of the clamp.
ECA11400CAUTION:
Use only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem.
Your Yamaha engine has been de-
signed to use premium unleaded
gasoline with a research octane num-
ber of 95 or higher. If knocking (or
pinging) occurs, use a gasoline of a
different brand. Use of unleaded fuel
will extend spark plug life and reduce
maintenance costs.
EAU13431
Catalytic converter
This model is equipped with a catalyt-
ic converter in the exhaust system.
EWA10860
WARNING0
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-
ing any maintenance work.

A. Distance (spring preload)
Adjust the spring preload as follows.
1. Loosen the locknut.
2. To increase the spring preload
and thereby harden the suspen-
sion, turn the adjusting nut in di-
rection (a). To decrease the
spring preload and thereby soften
the suspension, turn the adjusting
nut in direction (b).
NOTE:
Use the special wrench included
in the owner's tool kit to make the
adjustment.
The spring preload setting is de-
termined by measuring distance
A, shown in the illustration. The
longer distance A is, the lower the
spring preload; the shorter dis-
tance A is, the higher the spring
preload. With each complete turn
of the adjusting nut, distance A
changes by 1.5 mm (0.059 in).
When measuring distance A, the
rear wheel must be raised off the
ground. (See page 6-36).

Sidestand
1. Sidestand
The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the motorcycle upright.
NOTE:
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situa-
tions. (See further down for an expla-
nation of the ignition circuit cut-off sys-
tem.)

WARNING0
This shock absorber contains high-
ly pressurized nitrogen gas. For
proper handling, read and under-
stand the following information be-
fore handling the shock absorber.
The manufacturer cannot be held
responsible for property damage or
personal injury that may result from
improper handling.
Do not tamper with or attempt
to open the gas cylinder.
Do not subject the shock ab-
sorber to an open flame or oth-
er high heat sources, otherwise
it may explode due to exces-
sive gas pressure.
Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.
Always have a Yamaha dealer
service the shock absorber.
Tightening torque:
Locknut:
45 Nm (4.5 m·kgf, 32.5 ft·lbf)

PERIODIC MAINTENANCE AND MINOR REPAIR
EWA10600
WARNING0
This motorcycle is fitted with super-
high-speed tires. Note the following
points in order to make the most ef-
ficient use of these tires.
Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super
high speeds.
Brand-new tires can have a rel-
atively poor grip on certain
road surfaces until they have
been "broken in". Therefore, it
is advisable before doing any
high-speed riding to ride con-
servatively for approximately
100 km (60 mi) after installing a
new tire.
The tires must be warmed up
before a high-speed run.
Always adjust the tire air pres-
sure according to the operating
conditions.
EAU21960
Cast wheels
To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points regard-
ing 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 characteris-
tics.

1. Locknut
2. Adjusting bolt
3. Clutch lever free play
The clutch lever free play should mea-
sure 10.0-15.0 mm (0.39-0.59 in) as
shown. Periodically check the clutch
lever free play and, if necessary, ad-
just it as follows.
1. Loosen the locknut at the clutch
lever.
2. To increase the clutch lever free
play, turn the adjusting bolt in di-
rection (a). To decrease the clutch
lever free play, turn the adjusting
bolt in direction (b).

rest of the procedure, otherwise pro-
ceed as follows.

ified in the periodic maintenance and
lubrication chart.

PERIODIC MAINTENANCE AND MINOR REPAIR
Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.
Before riding, check that the brake flu-
id is above the minimum level mark
and replenish if necessary. A low
brake fluid level may indicate worn
brake pads and/or brake system leak-
age. 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
brake fluid reservoir is level.
Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing 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 performance.
Be careful that water does not en-
ter 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 paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid imme-
diately.
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.

Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addi-
tion, have the oil seals of the master
cylinders and calipers as well as the
brake hoses replaced at the intervals
listed below or whenever they are
damaged or leaking.
Oil seals: Replace every two
years.
Brake hoses: Replace every four
years.

Drive chain slack
The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU22771
To check the drive chain slack
1. Drive chain slack
1. Place the motorcycle on the side-
stand.
NOTE:
When checking and adjusting the dri-
ve chain slack, there should be no
weight on the motorcycle.
2. Shift the transmission into the
neutral position.
3. Move the rear wheel by pushing
the motorcycle to locate the tight-
est portion of the drive chain, and
then measure the drive chain
slack as shown.
4. If the drive chain slack is incor-
rect, adjust it as follows.
Drive chain slack:
40.0-50.0 mm (1.57-1.97 in)
EAU34311
To adjust the drive chain slack
1. Loosen the axle nut and the lock-
nut on each side of the swingarm.
2. To tighten the drive chain, turn the
adjusting bolt on each side of the
swingarm in direction (a). To
loosen the drive chain, turn the
adjusting bolt on each side 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 po-
sition for proper wheel alignment.

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.
ECA10581CAUTION:
The drive chain must be lubricated
after washing the motorcycle and
riding in the rain.
1. Clean the drive chain with
kerosene and a small soft brush.
ECA11120CAUTION:
To prevent damaging the O-rings,
do not clean the drive chain with
steam cleaners, high-pressure
washers or inappropriate solvents. 3. Tighten the locknuts, then the
axle nut to their specified torques.
