Measurement mode (for calibrating
the distance-compensation tripme-
ter’s reading)
The distance-compensation tripmeter
is a feature intended to provide a more
accurate tripmeter reading for enduro
riding. Calibrating this meter in accor-
dance with the distances specified on
the enduro course map will help famil-
iarize the rider with the course. In addi-
tion, calibrating the meter may also be
necessary when using tire, wheel,
chain sprocket sizes, etc. other than
specified. For further information con-
cerning the use of this meter, please
consult your nearby Yamaha dealer.
Calibrate the distance-compensation
tripmeter as follows.
To increase the reading, push the
“SLCT 1” button. To decrease the read-
ing, push the “SLCT 2” button. Pushing and holding either button will increase
or decrease the reading continuously
until the button is released.
TIPCalibrating the reading of the dis-
tance-compensation tripmeter is possi-
ble regardless of the stopwatchoperation.
Resetting the distance-compensa-
tion tripmeter or the distance-com-
pensation tripmeter in combination
with the stopwatchTIPResetting can be made only to the dis-
tance-compensation tripmeter or to the
distance-compensation tripmeter incombination with the stopwatch.
Resetting the distance-compensationtripmeter1. Check that the stopwatch mea-
surement is in operation.
2. Reset the distance-compensation tripmeter to zero by pushing the
“RST” button for at least two sec-
onds. Resetting the distance-compensation
tripmeter in combination with the stop-watch1. Stop the stopwatch.
2. Reset the distance-compensation
tripmeter and the stopwatch to
zero by pushing the “RST” button
for at least two seconds.

FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, followthese instructions. 1. Before refueling, turn off the en- gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters and
clothes dryers.
2. Do not overfill the fuel tank. Stop filling when the fuel reaches the
bottom of the filler tube. Because
fuel expands when it heats up,
heat from the engine or the sun
can cause fuel to spill out of the
fuel tank. 3. Wipe up any spilled fuel immedi-
ately. NOTICE: Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may deteri-
orate painted surfaces or plastic
parts.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some gasoline in your eyes, see your doctor immedi-
ately. If gasoline spills on your skin,
wash with soap and water. If gaso-
line spills on your clothing, change
your clothes.
EAU13392
NOTICE
ECA11401
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

Fuel tank breather hoseBefore operating the motorcycle:
Check the fuel tank breather hose
connection.

Check the fuel tank breather hose
for cracks or damage, and replace
it if necessary.

Make sure that the end of the fuel
tank breather hose is not blocked,
and clean it if necessary.
TIPIf the fuel tank breather hose falls out,
reinstall it on the fuel tank cap with the
arrow mark on the one-way valve point-ed downward as shown.

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.

Adjusting the front fork
WARNING
EWA10181
Always adjust both fork legs equal-
ly, otherwise poor handling and lossof stability may result.
This front fork is equipped with rebound
damping force adjusting screws and
compression damping force adjusting
screws.NOTICE
ECA10102
To avoid damaging the mechanism,
do not attempt to turn beyond themaximum or minimum settings.
Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting screw on each
fork leg in direction (a). To decrease the
rebound damping force and thereby
soften the rebound damping, turn the
adjusting screw on each fork leg in di-
rection (b). Compression damping force
To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting screw
on each fork leg in direction (a). To de-
crease the compression damping force
and thereby soften the compression
damping, turn the adjusting screw on

TIPAlthough 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 the
specifications as necessary.

Front fork bleeding
WARNING
EWA10201
Always bleed both fork legs, other-
wise poor handling and loss of sta-bility may result.
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 front fork as follows.
1. Lift the front wheel off the ground according to the procedure on
page 6-37.TIPWhen bleeding the front fork, there
should be no weight on the front end ofthe vehicle.
2. Remove the bleed screws and al- low all of the air to escape from
each fork leg.
