curs, use a gasoline of a different brand
or premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.
EAU13412
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
minimum level as shown in the illustra-
tion, add a sufficient amount of the rec-
ommended 2-stroke engine oil as
follows.
TIP
Make 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.)

FOR YOUR SAFETY – PRE-OPERATION CHECKS
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:

3. 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
acceleration 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.

Transmission oil
The transmission oil level should be
checked before each ride. In addition,
the transmission oil must be changed
at the intervals specified in the periodic
maintenance and lubrication chart.
To check the transmission oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
TIP
Make sure that the vehicle is positionedstraight up when checking the oil level.
A slight tilt to the side can result in a
false reading.
2. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in), and then remove it
again to check the oil level.
TIP
The transmission oil should be be-
tween the minimum and maximum lev-
el marks.
3. If the oil is below the minimum lev-
el mark, add sufficient oil of the
recommended type to raise it to
the correct level.
4. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
To change the transmission oil
1. Place an oil pan under the trans-
mission to collect the used oil.
2. Remove the oil filler cap and drain
bolt to drain the oil from the trans-
mission.
3. Install the transmission oil drain
bolt, and then tighten it to the spec-
ified torque.
4. Refill with the specified amount of
the recommended transmission
oil, and then install and tighten the
oil filler cap.

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.
EAU41162
Cleaning the air filter element
The air filter element should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
Clean the air filter element more fre-
quently 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.
Recommended transmission oil:
