Fuel tank cap To open the fuel tank cap
Open the fuel tank cap lock cover, in-
sert the key into the lock, and then turn
it 1/4 turn clockwise. The lock will be re-
leased and the fuel tank cap can be
opened.
To close the fuel tank cap
1. Push the fuel tank cap into position
with the key inserted in the lock.
2. Turn the key counterclockwise to
the original position, remove it, and
then close the lock cover.
NOTE:The fuel tank cap cannot be closed un-
less the key is in the lock. In addition,
the key cannot be removed if the cap isnot properly closed and locked.
WARNING
EWA11090
Make sure that the fuel tank cap isproperly closed before riding.
EAU13220
Fuel Make sure that there is sufficient fuel in
the tank. When refueling, be sure to in-
sert the pump nozzle into the fuel tank
filler hole and to fill the tank to the bot-
tom of the filler tube as shown.
WARNING
EWA10880


Do not overfill the fuel tank, oth-
erwise it may overflow when the
fuel warms up and expands.


Avoid spilling fuel on the hot en-gine.

CAUTION:
ECA10070
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since
fuel may deteriorate painted surfac-es or plastic parts.
EAU13390
CAUTION:
ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,as well as to the exhaust system.
Your Yamaha engine has been de-
signed to use premium unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging) oc-curs, use a gasoline of a different
brand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.
EAU34072
Fuel tank breather/overflow
hose Before operating the motorcycle:

Check the fuel tank breather/over-
flow hose connection.


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


Make sure that the end of the fuel
tank breather/overflow hose is not
blocked, and clean it if necessary.


Make sure that the end of the fuel
tank breather/overflow hose is po-
sitioned outside of the cowling.
Recommended fuel:
PREMIUM UNLEADED GASOLINE
ONLY
Fuel tank capacity:
18.0 L (4.76 US gal) (3.96 Imp.gal)
Fuel reserve amount (when the fuel
level warning light comes on):

Catalytic converter This model is equipped with a catalytic
converter 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.

tion, lift the front of the passenger
seat and pull it forward.
To install the passenger seat
1. Insert the projection on the rear of
the passenger seat into the seat
holder as shown, and then push
the front of the seat down to lock it
in place.
2. Remove the key.NOTE:Make sure that the seats are properlysecured before riding.

Helmet holders The helmet holders are located on the
bottom of the passenger seat.
To secure a helmet to a helmet hold-
er
1. Remove the passenger seat. (See
page 3-19.)
2. Attach the helmet to a helmet hold-
er, and then securely install the
passenger seat.
WARNING
EWA11040
Never ride with a helmet attached to
a helmet holder, since the helmet
may hit objects, causing loss of con-trol and possibly an accident.To release a helmet from a helmet
holder
Remove the passenger seat, remove
the helmet from the helmet holder, and
then install the seat.

Adjusting the front fork This front fork is equipped with spring
preload adjusting bolts, rebound damp-
ing force adjusting bolts and compres-
sion damping force adjusting bolts.
WARNING
EWA10180
Always adjust both fork legs equal-
ly, otherwise poor handling and lossof stability may result.
Spring preload
To make any adjustment of the spring
preload, the adjuster has to be set to
the standard position first.
To find the standard position, start by
turning the adjusting bolt on each fork
leg in direction (a) until it stops, then
check the alignment mark position.
a. If the alignment mark on the ad-
justing bolt is positioned past the
alignment mark on the front fork
cap as shown in illustration “A”,
turn the adjusting bolt in direction
(b) until the alignment marks
match.To set the standard position, turn
the adjusting bolt 3 complete turns
in direction (b), making sure the
alignment marks match.b. If the alignment mark on the ad-
justing bolt is positioned before the
alignment mark on the front fork
cap as shown in illustration “B”,
turn the adjusting bolt in direction
(b) until the alignment marks
match.
To set the standard position, turn
the adjusting bolt 2 complete turns
in direction (b), making sure the
alignment marks match.

To increase the spring preload and
thereby hardening it, turn the ad-
justing bolt in direction (a) from the
standard position, making sure to
turn the bolt complete turns so that
the alignment marks match.
To decrease the spring preload
and thereby softening it, turn the
adjusting bolt in direction (b) from
the standard position, making sure
to turn the bolt complete turns so
that the alignment marks match.Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting bolt on each fork
leg in direction (a). To decrease the re-
bound damping force and thereby soft-
en the rebound damping, turn the
adjusting bolt on each fork leg in direc-
tion (b).Compression damping force
To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting bolt on
each fork leg in direction (a). To de-
crease the compression damping force
and thereby soften the compression
damping, turn the adjusting bolt on
each fork leg in direction (b).

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.

WARNING
EWA10220
This shock absorber contains highly
pressurized nitrogen gas. For prop-
er handling, read and understand
the following information before
handling the shock absorber. 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 cylinder.


Do not subject the shock ab-
sorber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.


Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.


Always have a Yamaha dealerservice the shock absorber.
