ventilated areas. If you experience any
symptoms of carbon monoxide poi-
soning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.
 Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.
 Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
 Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loa din g
Adding accessories to your motorcycle
can adversely affect stability and han-
dling if the weight distribution of the
motorcycle is changed. To avoid the
possibility of an accident, use extreme
caution when adding accessories to
your motorcycle. Use extra care when
riding a motorcycle that has added ac-
cessories. Here are some general
guidelines to follow if adding accesso-
ries to your motorcycle:
Operation of an overload ed vehicle
coul d cause an acci dent.
 The weight of the operator must
not exceed 50.0 kg (110 lb).
 Accessory weight should be kept
as low and close to the motorcy-
cle as possible. Securely pack
your heaviest items as close to the
center of the vehicle as possible
and make sure to distribute the weight as evenly as possible on
both sides of the motorcycle to
minimize imbalance or instability.
 Shifting weights can create a sud-
den imbalance. Make sure that
accessories are securely attached
to the motorcycle before riding.
Check accessory mounts fre-
quently.
• Properly adjust the suspension for your load (suspension-ad-
justable models only), and
check the condition and pres-
sure of your tires.
• Never attach any large or heavy items to the handlebar, front
fork, or front fender.
Genuine Yamaha Accessories
Choosing accessories for your vehicle
is an important decision. Genuine
Yamaha accessories, which are avail- able only from a Yamaha dealer, have
been designed, tested, and approved
by Yamaha for use on your vehicle.
Many companies with no connection
to Yamaha manufacture parts and ac-
cessories or offer other modifications
for Yamaha vehicles. Yamaha is not in
a position to test the products that
these aftermarket companies produce.
Therefore, Yamaha can neither en-
dorse nor recommend the use of ac-
cessories not sold by Yamaha or
modifications not specifically recom-
mended by Yamaha, even if sold and
installed by a Yamaha dealer.


Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
 Shift the transmission in 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 mo-
torcycle, such as the frame or up-
per front fork triple clamp (and not,
for example, to rubber-mounted
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 mo-
torcycle will not bounce exces-
sively during transport.

3. Install the protector.
TIP
Install the protector so that the
side with the notch is facing rear-
ward.
 When turning the damping force
adjuster in direction (a), the 0 click
position and the 1 click position
may be the same.
 When turning the damping force
adjuster in direction (b), it may
click beyond the stated specifica- tions, however such adjustments
are ineffective and may damage
the suspension.

1. Remove the rubber cap by pulling it out of the front fork leg.
2. Turn the adjusting screw in direc- tion (a) to increase the compres-
sion damping force. Turn the
adjusting screw in direction (b) to
decrease the compression damp-
ing force. To set the compression
damping force, turn the adjuster in
direction (a) until it stops, and then
count the clicks in direction (b).
3. Install the rubber cap.

adjuster in direction (a), the 0 click
position and the 1 click position
may be the same.

Front fork b leedin g
When riding in extremely rough condi-
tions, the air temperature and pressure
in the front fork will rise. This will in-
crease the spring preload and harden
the front suspension. If this occurs,
bleed the air from each front fork leg.
WARNING
EWA10201
Always blee d b oth fork le gs, other-
wise poor han dlin g an d loss of sta-
b ility may result.
To bleed the front fork legs
1. Remove the protector.
2. Place the motorcycle on a suitable
stand. (See page 7-27.)
3. Make sure the front wheel is off the ground and the area near the
bleed screws is clean.
4. Remove the bleed screws.
