Checkin g the throttle grip free
play
Measure the throttle grip free play as
shown.
Periodically check the throttle grip free
play and, if necessary, have a Yamaha
dealer adjust it.
EAU21403
Valve clearance
The valves are an important engine
component, and since valve clearance
changes with use, they must be
checked and adjusted at the intervals
specified in the periodic maintenance
chart. Unadjusted valves can result in
improper air-fuel mixture, engine
noise, and eventually engine damage.
To prevent this from occurring, have
your Yamaha dealer check and adjust
the valve clearance at regular intervals.
TIP
This service must be performed when
the engine is cold.1. Throttle grip free play

Tires
Tires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
WARNING
EWA10504
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or d eath from loss of
control.  The tire air pressure must be
checked and a djuste d on col d
tires (i.e., when the temperature
of the tires equals the am bient
temperature).
 The tire air pressure must be
a d juste d in accor dance with the
ri din g speed and with the total
wei ght of ri der, passen ger, car-
g o, an d accessories approve d
for this mo del.WARNING
EWA10512
Never overloa d your vehicle. Opera-
tion of an overloa ded vehicle coul d
cause an acci dent.
Tire inspection
The tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail
or glass fragments in it, or if the side-
wall is cracked, have a Yamaha dealer
replace the tire immediately.
Col d tire air pressure:
1 person: Front:250 kPa (2.50 kgf/cm², 36 psi)
Rear: 290 kPa (2.90 kgf/cm², 42 psi)

ply with the local regulations.
WARNING
EWA10472
 Have a Yamaha dealer replace
excessively worn tires. Besi des
b ein g ille gal, operatin g the vehi-
cle with excessively worn tires
d ecreases ri din g sta bility an d
can lead to loss of control.
 The replacement of all wheel
and b rake-relate d parts, inclu d-
in g the tires, shoul d b e left to a
Yamaha dealer, who has the
necessary professional knowl-
e dge an d experience to do so.
 Ride at mo derate speed s after
chan gin g a tire since the tire
surface must first be “ broken
in” for it to d evelop its optimal
characteristics.
Tire information This model is equipped with tubeless
tires and tire air valves.
Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.
WARNING


The front an d rear tires shoul d
b e of the same make an d d e-
si gn, otherwise the han dlin g
characteristics of the motorcy-
cle may b e different, which
coul d lea d to an acci dent.
 Always make sure that the valve
caps are securely installe d to
prevent air pressure leakag e.
 Use only the tire valves an d
valve cores liste d below to

WARNING
EWA10601
This motorcycle is fitte d with super-
hi gh-spee d tires. Note the followin g
points in or der to make the most ef-
ficient use of these tires.  Use only the specified replace-
ment tires. Other tires may run
the dan ger of bursting at super
hi gh spee ds.
 Bran d-new tires can have a rel-
atively poor g rip on certain roa d
surfaces until they have been
“ b roken in”. Therefore, it is a d-
visa ble before doin g any hi gh-
speed ridin g to ri de conserva-
tively for approximately 100 km
(60 mi) after installin g a new tire.
 The tires must be warmed up
b efore a hi gh-spee d run.

Cast wheels
To maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
 The wheel rims should be
checked for cracks, bends, warp-
age or other damage 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 de-
formed 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.

YCC-S clutch
This model is equipped with a hydrau-
lic clutch, therefore, it is necessary to
check the YCC-S clutch fluid level and
check the hydraulic system for leak-
age. (See page 6-25.)
TIP
If shifting becomes rough or clutch
slippage occurs, or if you notice poor
acceleration or engine stalls, have a
Yamaha dealer check the clutch for wear.
EAU37914
Checkin g 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
EWA14212
A soft or spon gy feelin g in the b rake
lever can in dicate the presence of
air in the hy draulic system. If there is
air in the hy draulic system, have a
Yamaha dealer blee d the system be-
fore operatin g the vehicle. Air in the
hy draulic system will diminish the
b rakin g performance, which may re-
sult in loss of control an d an acci-
d ent.

Brake li ght switches
The brake light should come on just
before braking takes effect. The brake
light is activated by switches connect-
ed to the brake lever and brake pedal.
Since the brake light switches are
components of the anti-lock brake sys-
tem, they should only be serviced by a
Yamaha dealer.
EAU22393
Checkin g the front an d rear
b rake pa ds
The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU43432Front brake pad s
The front brake calipers are equipped
with two sets of brake pads.
Each front brake pad is provided with a
wear indicator groove, which allows
you to check the brake pad wear with-
out having to disassemble the brake.
To check a brake pad for wear, check
its wear indicator groove. If a brake
pad has worn to the point that the wear
indicator groove has almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
