4-PRE-OPERATION CHECKSThe condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.

NOTE:_

The annual checks must be performed every year, except if a kilometer-based maintenance is performed instead.


From 50,000 km, repeat the maintenance intervals starting from 10,000 km.


Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and techni-
cal skills.

NOTE:_

The air filter needs more frequent service if you are riding in unusually wet or dusty areas.


Hydraulic brake and clutch service
Regularly check and, if necessary, correct the brake and clutch fluid levels.
Every two years replace the internal components of the brake master cylinders and calipers as well as clutch master
and release cylinders, and change the brake and clutch fluids.
Replace the brake and clutch hoses every four years and if cracked or damaged.

Clutch lever free play 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 lev-
el and check the hydraulic system for
leakage before each ride. If the clutch
lever free play does become exces-
sive, and shifting becomes rough or
clutch slippage occurs, causing poor
acceleration, there may be air in the
clutch system. If there is air in the hy-
draulic system, have a Yamaha dealer
bleed the system before operating the
motorcycle.
EAU00712
Adjusting the brake pedal
position The top of the brake pedal should be
positioned approximately 42 mm below
the top of the footrest as shown. Peri-
odically check the brake pedal position
and, if necessary, have a Yamaha
dealer adjust it.
EW000109
WARNING
_ A soft or spongy feeling in the brake
pedal 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
accident. _

Rear brake pads
Check each rear brake pad for damage
and measure the lining thickness. If a
brake pad is damaged or if the lining
thickness is less than 0.8 mm, have a
Yamaha dealer replace the brake pads
as a set.
EAU05024
Checking the brake and clutch
fluid levels Insufficient brake fluid may allow air to
enter the brake or clutch systems, pos-
sibly causing them to become ineffec-
tive.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake flu-
id 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.
NOTE:_ The rear brake fluid reservoir is located
behind panel F. (See page 6-7 for pan-
el removal and installation proce-
dures.) _

6 Observe these precautions:


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


Use only the recommended quali-
ty 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.


The brake or clutch fluid reservoir
diaphragm will lose its shape from
the negative pressure if the fluid
level goes down too far. Be sure to
return the diaphragm to its original
shape before installing it into the
brake or clutch fluid reservoir.


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, and dirt may clog the ABS
hydraulic unit valves.


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
gradually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.

EAU03984
Changing the brake and
clutch fluids Have a Yamaha dealer change the
brake and clutch fluids at the intervals
specified in the NOTE 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.
EAU02962
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 ca-
bles and cable ends should be lubricat-
ed if necessary. If a cable is damaged
or does not move smoothly, have a
Yamaha dealer check or replace it.
EW000112
WARNING
_ Damage to the outer sheath may in-
terfere with proper cable operation
and will cause the inner cable to
rust. Replace a damaged cable as
soon as possible to prevent unsafe
conditions. _
EAU04034
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.
Recommended lubricant:
Engine oil
