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 “SE-
LECT 1” button. To decrease the read-
ing, push the “SELECT 2” button.
Pushing and holding either button will
increase or decrease the reading con-
tinuously until the button is released.TIPCalibrating the reading of the distance-
compensation tripmeter is possible re-
gardless of the stopwatch operation.

This model is equipped with a self-diag-
nosis device for various electrical cir-
cuits.
If a problem is detected in any of those
circuits, the engine trouble warning light
will come on and the display will indi-
cate an error code.
If the display indicates any error codes,
note the code number, and then have a
Yamaha dealer check the vehicle.
NOTICE
ECA11590
If the display indicates an error
code, the vehicle should be checked
as soon as possible in order to avoid
engine damage.

Fuel tank cap To remove the fuel tank cap
1. Insert the key into the lock and turn
it counterclockwise as shown.
2. Turn the fuel tank cap counter-
clockwise and pull it off.
To install the fuel tank cap
1. Insert the fuel tank cap into the
tank opening with the key inserted
in the lock, and then turn the cap
clockwise.
2. Turn the key clockwise, and then
remove it.
TIPThe fuel tank cap cannot be installed
unless the key is in the lock. In addition,
the key cannot be removed if the cap is
not properly installed and locked.
WARNING
EWA10121
Make sure that the fuel tank cap is
properly closed and locked before
riding. Leaking fuel is a fire hazard.
EAU13221
Fuel Make sure there is sufficient gasoline in
the tank.
WARNING
EWA10881
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these 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. When
refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. 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.

WARNING
EWA15151
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.

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 differentbrand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.

Catalytic converter This model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10862
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 of
heat.
NOTICE

Use only unleaded gasoline. The use
of leaded gasoline will cause unre-
pairable damage to the catalytic
converter.

Adjusting the front fork
WARNING
EWA10180
Always adjust both fork legs equal-
ly, otherwise poor handling and loss
of stability may result.This front fork is equipped with rebound
damping force adjusting screws and
compression damping force adjusting
screws.NOTICE

To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum 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

Front fork bleeding
WARNING
EWA10200
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. Elevate the front wheel by placing
a suitable stand under the engine.TIPWhen bleeding the front fork, there
should be no weight on the front end of
the vehicle.2. Remove the bleed screws and al-
low all of the air to escape from
each fork leg.3. Install the bleed screws.
