or premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.

Fuel tank breather hose Before operating the motorcycle:

Check the fuel tank breather hose
connection.


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


Make sure that the fuel tank
breather hose is not blocked, and
clean it if necessary.
EAU41202
2-stroke engine oil Make sure that there is sufficient oil in
the 2-stroke engine oil tank. If the 2-
stroke engine oil is at or below the min-
imum level as shown in the illustration,
add a sufficient amount of the recom-
mended 2-stroke engine oil as follows.TIPMake sure that the motorcycle is posi-
tioned straight up when checking the 2-
stroke engine oil level. A slight tilt to the
side can result in a false reading.1. Remove the seat. (See page 4-7.)
2. Remove the 2-stroke engine oil
tank cap and add the recommend-
ed oil.

Fuel cock The fuel cock supplies fuel from the
tank to the carburetor while filtering it al-
so.
The fuel cock has three positions:
OFF
With the lever in this position, fuel will
not flow. Always return the lever to this
position when the engine is not running.ON
With the lever in this position, fuel flows
to the carburetor. Normal riding is done
with the lever in this position.

EAU15596
Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always follow the inspection
and maintenance procedures and schedules described in the Owner’s Manual.
WARNING
EWA11151
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment damage.
Do not operate the vehicle if you find any problem. If a problem cannot be corrected by the procedures provided in
this manual, have the vehicle inspected by a Yamaha dealer.Before using this vehicle, check the following points:
ITEM CHECKS PAGE
FuelCheck fuel level in fuel tank.
Refuel if necessary.
Check fuel line for leakage.
Check the fuel tank breather/overflow hose for obstructions, cracks or damage,
and check the hose connection.4-3, 4-4
2-stroke engine oilCheck oil level in oil tank.
If necessary, add recommended oil to specified level.
Check vehicle for oil leakage.4-4
Transmission oilCheck oil level in transmission case.
If necessary, add recommended oil to specified level.7-8
Front brakeCheck operation.
Lubricate cable if necessary.
Check lever free play.
Adjust if necessary.7-14, 7-16
Rear brakeCheck operation.
Check pedal free play.
Adjust if necessary.7-15, 7-16

OPERATION AND IMPORTANT RIDING POINTS
6-3
63. Open the throttle gradually.
4. Once the motorcycle has reached
a speed high enough to change
gears, close the throttle.
5. Shift into second gear and release
the shift pedal.
6. Open the throttle gradually.
7. Follow the same procedure when
shifting to the next higher gear.
EAU16710
To decelerate
1. Close the throttle and apply both
the front and the rear brakes to
slow the motorcycle.
2. Downshift through the gears and
shift the transmission into the neu-
tral position when the motorcycle
is almost completely stopped.
EAU39920
Engine break-in There is never a more important period
in the life of your engine than the first 5
hours of riding. It is also important to ac-
custom the rider to the motorcycle dur-
ing this time. Please read the following
information carefully.
Since the engine is brand new, do not
put an excessive load on it for the first 5
hours of operation. The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided. However, momentary full-
throttle operation under load (i.e., two
to three seconds maximum) does not
harm the engine. Each full-throttle ac-
celeration should be followed with a
substantial rest period for the engine.
To allow the engine to cool down from
the temporary buildup of heat, cruise at
a lower engine speed.
After the first 5 hours of operation, thor-
oughly check the motorcycle for loose
parts, oil leakage and any other prob-
lems. Be sure to inspect and make ad-justments thoroughly, especially cable
and drive chain slack and loose
spokes. In addition, check all fittings
and fasteners for looseness, and tight-
en if necessary.
NOTICE
ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

NOTICE
ECA10452


In order to prevent clutch slip-
page (since the transmission oil
also lubricates the clutch), do
not mix any chemical additives.
Do not use oils with a diesel
specification of “CD” or oils of a
higher quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.


Make sure that no foreign mate-
rial enters the transmission.
5. Start the engine, and then let it idle
for several minutes while checking
the transmission for oil leakage. If
oil is leaking, immediately turn the
engine off and check for the cause.
EAU41163
Cleaning the air filter element The air filter element should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
Clean or, if necessary, replace the air
filter element more frequently if you are
riding in unusually wet or dusty areas.
1. Remove the air filter case cover by
removing the screws.
2. Pull the air filter element out.3. Remove the sponge material from
the air filter case cover, clean it
with solvent, and then squeeze the
remaining solvent out.1. Air filter case cover

to the entire surface of the sponge
material, and then squeeze the ex-
cess oil out.
TIPThe sponge material should be wet but
not dripping.5. Install the sponge material onto
the air filter case cover.
6. Insert the air filter element into the
air filter case. NOTICE: Make sure
that the air filter element is prop-
erly seated in the air filter case.
The engine should never be op-erated without the air filter ele-
ment installed, otherwise the
piston(s) and/or cylinder(s) may
become excessively worn.
[ECA10481]
7. Install the air filter case cover by in-
stalling the screws.
EAU41232
Cleaning the spark arrester The spark arrester should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
WARNING
EWA10980


Always let the exhaust system
cool prior to touching exhaust
components.


Do not start the engine when
cleaning the exhaust system.
1. Remove the tailpipe by removing
the bolt, and then pulling it out of
the muffler.
Recommended oil:
Yamaha foam air filter oil or other
quality foam air filter oil

Cleaning and lubricating the
drive chain The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly wear
out, especially when riding in dusty or
wet areas. Service the drive chain as
follows.NOTICE
ECA10583
The drive chain must be lubricated
after washing the motorcycle, riding
in the rain or riding in wet areas.1. Remove all dirt and mud from the
drive chain with a brush or cloth.TIPFor a thorough cleaning, have a
Yamaha dealer remove the drive chain
and soak it in solvent.2. Spray Yamaha Chain and Cable
Lube or a high-quality spray-type
drive chain lubricant on the entire
chain, making sure that all side
plates and rollers have been suffi-
ciently oiled.
EAU41842
Checking and lubricating the
cables The operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubricat-
ed if necessary. If a cable is damaged
or does not move smoothly, have a
Yamaha dealer check or replace it.
WARNING! Damage to the outer
housing of cables may result in in-
ternal rusting and cause interfer-
ence with cable movement. Replace
damaged cables as soon as possi-
ble to prevent unsafe conditions.[EWA10711]EAU23113
Checking and lubricating the
throttle grip and cable The operation of the throttle grip should
be checked before each ride. In addi-
tion, the cable should be lubricated by a
Yamaha dealer at the intervals speci-
fied in the periodic maintenance chart.
The throttle cable is equipped with a
rubber boot. Make sure that the boot is
securely installed. Even though the
boot is installed correctly, it does not
completely protect the cable from water
entry. Therefore, use care not to pour
water directly onto the boot or cable
when washing the vehicle. If the cable
or boot becomes dirty, wipe clean with
a moist cloth.
Recommended lubricant:
Yamaha Chain and Cable Lube or 4-
stroke engine oil
