spark plug life and reduce maintenance
costs.

Fuel tank breather hose Before operating the motorcycle:

Check the fuel tank breather hose
connection.


Check the fuel tank breather hose
for cracks or damage, and replace
it if damaged.


Make sure that the fuel tank
breather hose is not blocked, and
clean it if necessary.
EAU13433
Catalytic converter This model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10862
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:

Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.


Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.


Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.


Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up ofheat.

Adjusting the shock absorber
assembly This shock absorber assembly is
equipped with a spring preload adjust-
ing nut.NOTICE
ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond themaximum or minimum settings.
Adjust the spring preload as follows.
1. Loosen the locknut.
2. To increase the spring preload and
thereby harden the suspension,
turn the adjusting nut in direction
(a). To decrease the spring pre-load and thereby soften the sus-
pension, turn the adjusting nut in
direction (b).


To make the adjustment, use
the special wrench and exten-
sion bar included in the addi-
tional tool kit, which was
handed out separately at the
purchase of the vehicle.


The spring preload setting is
determined by measuring dis-
tance A, shown in the illustra-
tion. The shorter distance A is,
the higher the spring preload;
the longer distance A is, the
lower the spring preload. With
each complete turn of the ad-
justing nut, distance A is
changed by 2.0 mm (0.08 in).

[ECA10121]WARNING
EWA10221
This shock absorber assembly con-
tains highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assembly.

Do not tamper with or attempt to
open the cylinder assembly.


Do not subject the shock ab-
sorber assembly to an open
flame or other high heat source.
This may cause the unit to ex-
plode due to excessive gas
pressure.


Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.


Do not dispose of a damaged or
worn-out shock absorber as-
sembly yourself. Take the shock
absorber assembly to a Yamahadealer for any service.
EAU15281
EXUP system This model is equipped with Yamaha’s
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine
power by means of a valve that regu-
lates the diameter of the exhaust pipe.
The EXUP system valve is constantly
adjusted in accordance with the engine
speed by a computer-controlled servo-
motor.NOTICE
ECA10191


The EXUP system has been set
and extensively tested at the
Yamaha factory. Changing
these settings without sufficient
technical knowledge may result
in poor performance of or dam-
age to the engine.


If the EXUP system cannot be
heard when the main switch is
turned on, have a Yamaha deal-er check it.
Spring preload:
Minimum (hard):
Distance A = 162 mm (6.38 in)
Standard:
Distance A = 171 mm (6.73 in)
Maximum (soft):
Distance A = 171 mm (6.73 in)
Tightening torque:
Locknut:
30 Nm (3.0 m·kgf, 22 ft·lbf)

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.
Recommended brake and clutch flu-
id:
DOT 4 brake fluid
