
Check that the fuel cock (if
equipped) is in the off position and
that there are no fuel leaks.

Shift the transmission into gear (for
models with a manual transmis-
sion).

Secure the motorcycle with
tie-downs or suitable straps that
are attached to solid parts of the
motorcycle, such as the frame or
upper front fork triple clamp (and
not, for example, to rubber-mount-
ed handlebars or turn signals, or
parts that could break). Choose
the location for the straps carefully
so the straps will not rub against
painted surfaces during transport.

The suspension should be com-
pressed somewhat by the
tie-downs, if possible, so that the
motorcycle will not bounce exces-
sively during transport.

hol containing ethanol and that contain-
ing methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.

Fuel tank overflow hoseBefore operating the vehicle:
check the overflow hose connec-
tion.

check the overflow hose for dam-
age.

confirm the overflow hose is not
blocked.

confirm the overflow hose is routed
through the clamp.
TIPSee page 7-11 for canister information.
EAU13434
Catalytic converterThis model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10863
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.
NOTICE

Storage compartmentThe storage compartment is located
under the seat. (See page 4-20.)
When storing documents or other items
in the storage compartment, be sure to
wrap them in a plastic bag so that they
will not get wet. When washing the ve-
hicle, be careful not to let any water en-
ter the storage compartment.
WARNING
EWA15401
Do not exceed the maximum load of174 kg (384 lb) for the vehicle.
EAU76341
Adjusting the front fork
WARNING
EWA14671
Always adjust the spring preload on
both fork legs equally, otherwise
poor handling and loss of stabilitymay result.
Each front fork leg is equipped with a
spring preload adjusting bolt, the right
front fork leg is equipped with a re-
bound damping force adjusting screw
and the left front fork leg with a com-
pression damping force adjusting
screw.NOTICE
ECA10102
To avoid damaging the mechanism,
do not attempt to turn beyond themaximum or minimum settings.
Spring preload
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolt on each fork leg in di-
rection (a). To decrease the spring pre-
load and thereby soften the
suspension, turn the adjusting bolt on each fork leg in direction (b).
The spring preload setting is deter-
mined by measuring distance A, shown
in the illustration. The shorter distance
A is, the higher the spring preload; the
longer distance A is, the lower the
spring preload.

12 Rebound damping force
The rebound damping force is adjusted
on the right front fork leg only. To in-
crease the rebound damping force and
thereby harden the rebound damping,
turn the adjusting screw in direction (a).
To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting screw in di-
rection (b).
TIPBe sure to perform this adjustment onthe right front fork leg.
Compression damping force
The compression damping force is ad-
justed on the left front fork leg only. To
increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting screw
in direction (a). To decrease the com-
pression damping force and therebysoften the compression damping, turn
the adjusting screw in direction (b).
TIPBe sure to perform this adjustment onthe left front fork leg.TIP

mechanism may not exactly match
the above specifications due to
small differences in production, the
actual number of clicks always
represents the entire adjusting
range. To obtain a precise adjust-
ment, check the number of clicks
of each damping force adjusting
mechanism and modify the specifi-
cations as necessary.

juster in direction (a), the 0 click
position and the 1 click positionmay be the same.

assemblyThis shock absorber assembly is
equipped with a spring preload adjust-
ing ring and a rebound damping force
adjusting screw.NOTICE

To avoid damaging the mechanism,
do not attempt to turn beyond themaximum or minimum settings.
Spring preload
To increase the spring preload and
thereby harden the suspension, turn
the adjusting ring in direction (a). To de-
crease the spring preload and thereby
soften the suspension, turn the adjust-
ing ring in direction (b).

Align the appropriate notch in the
adjusting ring with the position in-
dicator on the shock absorber.

ing, turn the adjusting screw in direction

force and thereby soften the rebound
damping, turn the adjusting screw in di-

may not exactly match the specifica-
tions listed due to small differences inproduction.
WARNING
EWA10222
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 Yamaha
dealer for any service.

If a fuse is blown, replace it as follows.
1. Turn the key to “OFF” and turn off the electrical circuit in question.
2. Remove the blown fuse, and then install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher amperage
rating than recommended to
avoid causing extensive dam-
age to the electrical system and
possibly a fire.
[EWA15132]
3. Turn the key to “ON” and turn on the electrical circuit in question to check if the device operates.
4. If the fuse immediately blows again, have a Yamaha dealer
check the electrical system.

wise until it stops.
4. Install the lens by installing the screw. NOTICE: Do not over-
tighten the screw, otherwise the
lens may break.

Supporting the motorcycleSince this model is not equipped with a
centerstand, use maintenance stands
when removing the front or rear wheel
or when performing other maintenance
that requires the motorcycle to stand up
right.
Check that the motorcycle is in a stable
and level position before starting any
maintenance.
EAU25872
TroubleshootingAlthough Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur dur-
ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the motorcycle
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look like
Yamaha parts, but they are often inferi-
or, have a shorter service life and can
lead to expensive repair bills.
WARNING
EWA15142
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the ar-
ea, including pilot lights from water
