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.

Catalytic converters This vehicle is equipped with catalytic
converters in the exhaust system.
WARNING
EWA10860
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-ing any maintenance work.CAUTION:
ECA10700
The following precautions must be
observed to prevent a fire hazard or
other damages.
Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.
Never park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.
Do not allow the engine to idletoo long.

CAUTION:
ECA10100
Never attempt to turn an adjusting
mechanism beyond the maximum orminimum settings.NOTE:Although the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences in
production, the actual number of clicks
always represents the entire adjusting
range. To obtain a precise adjustment,
it would be advisable to check the num-
ber of clicks of each damping force ad-
justing mechanism and to modify thespecifications as necessary.

Adjusting the shock absorber
assemblies Each shock absorber assembly is
equipped with a spring preload adjust-
ing ring and rebound and compression
damping force adjusting knobs.
WARNING
EWA10210
Always adjust both shock absorber
assemblies equally, otherwise poor
handling and loss of stability mayresult.
Spring preload
Adjust the spring preload as follows.
1. Loosen the lock screw 1/2 turn
counterclockwise.2. To increase the spring preload and
thereby harden the suspension,
turn the adjusting ring in direction
(a). To decrease the spring pre-
load and thereby soften the sus-
pension, turn the adjusting ring in
direction (b).
NOTE:
Use the special wrench included in
the owner’s tool kit to make this ad-
justment.
The spring preload setting is deter-
mined by measuring distance A,
shown in the illustration. The long-
er distance A is, the higher the
spring preload; the shorter dis-
tance A is, the lower the spring
preload. With each complete turn
of the adjusting ring, distance A
changes by 1.5 mm (0.06 in).
Be sure to turn the adjusting ring
so that the lock screw is facing out-ward.

WARNING
EWA10230
These shock absorbers contain
highly pressurized nitrogen gas. For
proper handling read and under-
stand the following information be-
fore handling the shock absorbers.
The manufacturer cannot be held re-
sponsible for property damage or
personal injury that may result from
improper handling.
Do not tamper with or attempt to
open the gas cylinders.
Do not subject the shock ab-
sorbers to an open flame or oth-
er high heat sources, otherwise
they may explode due to exces-
sive gas pressure.
Do not deform or damage the
gas cylinders in any way, as this
will result in poor damping per-
formance.
Always have a Yamaha dealerservice the shock absorbers.

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.CAUTION:
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.
EAU15301
Sidestand The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.NOTE:The built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See further down for an explanation ofthe ignition circuit cut-off system.)
WARNING
EWA10240
The vehicle must not be ridden with
the sidestand down, or if the side-
stand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly as describedbelow and have a Yamaha dealer re-
pair it if it does not function proper-
ly.

Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.WARNING

PRE-OPERATION CHECKS
4-1

EAU15593
The 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:Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very shorttime; and the added safety it assures is more than worth the time involved.
WARNING
EWA11150
If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operatingthe vehicle.U5WME5E0.book Page 1 Wednesday, December 5, 2007 10:30 AM
