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.

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.)

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:
See page 9-1.

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 condi-
tions.

EAU23111
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 at
the intervals specified in the periodic
maintenance chart.
EAU23120
Adjusting the Autolube pump
The Autolube pump is a vital and so-
phisticated component of the engine,
which must be adjusted by a Yamaha
dealer at the intervals specified in the
periodic maintenance and lubrication
chart.
Recommended lubricant:
Yamaha Chain and Cable Lube or
4-stroke engine oil

Checking the front fork
The condition and operation of the front
fork must be checked as follows at the
intervals specified in the periodic main-
tenance and lubrication chart.
To check the condition
Check the inner tubes for scratches,
damage and excessive oil leakage.
To check the operation
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
WARNING! To avoid injury,
securely support the vehicle so
there is no danger of it falling
over.
[EWA10751]
2. While applying the front brake,
push down hard on the handlebars
several times to check if the front
fork compresses and rebounds
smoothly.
NOTICE
ECA10590
If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or re-
pair it.
EAU23283
Checking the steering
Worn or loose steering bearings may
cause danger. Therefore, the operation
of the steering must be checked as fol-
lows at the intervals specified in the pe-
riodic maintenance and lubrication
chart.
1. Place a stand under the engine to
raise the front wheel off the
ground. (See page 7-21 for more
information.)
WARNING! To
avoid injury, securely support
the vehicle so there is no danger
of it falling over.
[EWA10751]
2. Hold the lower ends of the front
fork legs and try to move them for-
ward and backward. If any free
play can be felt, have a Yamaha
dealer check or repair the steering.
