FuelThis motorcycle has been designed to
use a premixed fuel of gasoline and 2-
stroke engine oil. Always mix the gaso-
line and oil in a clean container before
filling the fuel tank.NOTICE

Why Yamalu be
YAMALUBE oil is a Genuine YAMAHA Part born of the engineers’ passion
and belief that engine oil is an impor-
tant liquid engine component. We form
teams of specialists in the fields of me- chanical engineering, chemistry, elec-
tronics and track testing, and have
them develop the engine together with
the oil it will use. Yamalube oils take full
advantage of the base oil’s qualities
and blend in the ideal balance of addi-
tives to make sure the final oil clears
our performance standards. Thus,
Yamalube mineral, semisynthetic and synthetic oils have their own distinct
characters and value. Yamaha’s expe-
rience gained over many years of re-
search and development into oil since
the 1960’s helps make Yamalube the
best choice for your Yamaha engine.
If the recommended 2-stroke engine
oil is not available, use an equivalent
high-quality oil.
NOTICE
ECA15552
Never mix two bran ds of 2-stroke
en gine oil in the same batch. Always
use the same type of oil to ensure
maximum eng ine performance.
Shoul d it b e necessary to use a dif-
ferent oil b rand, b e sure to d rain the
fuel tank an d the car buretor float
cham ber of the ol d premixe d fuel
prior to filling with the new type.Gasoline
This model’s engine is designed to use
premium unleaded gasoline with a
pump octane number [(R+M)/2] of 91
or higher, or a research octane number
(RON) of 95 or higher. If knocking or
pinging occurs, try a gasoline of a dif-
ferent brand.NOTICE
ECA15591
Use only unlea ded g asoline. The use
of lea ded g asoline will cause severe
d amag e to internal en gine parts,
such as the piston rin gs as well as to
the exhaust system.

Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol should not
be used as it can cause engine or fuel
system problems.
Fillin
g the fuel tank
WARNING
EWA10882
Gasoline an d gasoline vapors are
extremely flammab le. To avoid fires
an d explosions an d to re duce 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. 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 spille d fuel with a clean,
d ry, soft cloth, since fuel may
d eteriorate painte d surfaces or
plastic parts.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous an d can
cause injury or death. Han dle gaso-
line with care. Never siphon gasoline
b y mouth. If you shoul d swallow
some gasoline or inhale a lot of g as-
oline vapor, or get some gasoline in
your eyes, see your doctor imme di-
ately. If g asoline spills on your skin,
wash with soap an d water. If gaso-
line spills on your clothin g, chan ge
your clothes.

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 fuel tank
breather hose is not blocked, and
clean it if necessary.
EAU41281
Fuel cockThe fuel cock supplies fuel from the
tank to the carburetor while filtering it
also.
The fuel cock has two positions:
OFF
With the lever in this position, fuel will
not flow. Always return the lever to this
position when the engine is not run-
ning. ON
With the lever in this position, fuel flows
to the carburetor. Normal riding is done
with the lever in this position.

Starter (choke) kno bStarting a cold engine requires a richer
air-fuel mixture, which is supplied by
the starter (choke).
Move the knob in direction (a) to turn
on the starter (choke).
Move the knob in direction (b) to turn
off the starter (choke).

KickstarterTo start the engine, fold out the kick-
starter lever, move it down lightly with
your foot until the gears engage, and
then push it down smoothly but force-
fully. This model is equipped with a pri-
mary kickstarter, allowing the engine to
be started in any gear if the clutch is
disengaged. However, shifting the
transmission into the neutral position
before starting is recommended.

Front fork blee din gWhen 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

Always blee d b oth fork le gs, other-
wise poor han dlin g an d loss of sta-

2. Place the motorcycle on a suitable
stand. (See page 7-26.) 3. Make sure the front wheel is off
the ground and the area near the
bleed screws is clean.
4. Remove the bleed screws.
5. Wait a few seconds, and then in- stall the bleed screws.
6. Install the protector.

Adjust the spring preload as follows. 1. Loosen the clamp bolts, and then remove the air filter joint.
2. Loosen the locknut.
3. Turn the adjusting nut in direction(a) to increase the spring preload.
Turn the adjusting nut in direction
(b) to decrease the spring preload. 
A special wrench can be ob-
tained at a Yamaha dealer to
make this adjustment.
 The spring preload setting is
determined by measuring
distance A, shown in the illus-
tration. The longer distance A
is, the lower the spring pre-
load; the shorter distance A
is, the higher the spring pre-
load. With each complete
turn of the adjusting nut, dis-
tance A is changed by 1.5
mm (0.06 in).
