NOTE:The engine oil should be between theminimum and maximum level marks.
4. If the engine oil is at or below the
minimum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.
To change the engine oil (with or
without oil filter element replace-
ment)
1. Start the engine, warm it up for
several minutes, and then turn it
off.2. Place an oil pan under the engine
to collect the used oil.
3. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.
NOTE:
Skip steps 4–7 if the oil filter element isnot being replaced.
4. Remove the outer and inner oil fil-
ter element covers by removing
the bolts.
5. Remove the oil filter element and
O-ring.

7. Install the oil filter element covers
by installing the bolts, and then
tighten them to the specified
torque.
8. Install the engine oil drain bolt, and
then tighten it to the specified
torque.
NOTE:Check the washer for damage and re-place it if necessary.9. Add the specified amount of the
recommended oil, and then install
and tighten the oil filler cap.
CAUTION:
ECA11620
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Make sure that no foreign mate-rial enters the crankcase.
10. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
11. Turn the engine off, and then
check the oil level and correct it if
necessary.

Final gear oil The final gear case must be checked
for oil leakage before each ride. If any
leakage is found, have a Yamaha deal-
er check and repair the vehicle. In addi-
tion, the final gear oil level must be
checked and the oil changed as follows
at the intervals specified in the periodic
maintenance and lubrication chart.
WARNING
EWA10370
Make sure that no foreign mate-
rial enters the final gear case.
Make sure that no oil gets on thetire or wheel.
To check the final gear oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
NOTE:
The final gear oil level must be
checked on a cold engine.
Make sure that the vehicle is posi-
tioned straight up when checking
the oil level. A slight tilt to the sidecan result in a false reading.2. Remove the oil filler bolt, and then
check the oil level in the final gear
case.
NOTE:The oil level should be at the brim of thefiller hole.
3. If the oil is below the brim of the fill-
er hole, add sufficient oil of the rec-
ommended type to raise it to the
correct level.
To change the final gear oil
1. Place an oil pan under the final
gear case to collect the used oil.2. Remove the oil filler bolt and drain
bolt to drain the oil from the final
gear case.
3. Install the final gear oil drain bolt,
and then tighten it to the specified
torque.
4. Add the recommended final gear
oil to the brim of the filler hole.
NOTE:GL4 is a quality rating. Hypoid gear oilsrated GL5 or GL6 may also be used.
5. Install the oil filler bolt, and then
tighten it to the specified torque.

When checking the fluid level,
make sure that the top of the mas-
ter cylinder is level by turning the
handlebars.
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if thebrake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
EAU22720
Changing the brake fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addition,
have the oil seals of the brake master
cylinder and caliper as well as the
brake hose replaced at the intervals
listed below or whenever they are dam-
aged or leaking.
Oil seals: Replace every two
years.
Brake hose: Replace every four
years.
Recommended brake fluid:

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
EWA10720
Damage to the outer sheath may in-
terfere with proper cable operation
and will cause the inner cable to
rust. Replace a damaged cable as
soon as possible to prevent unsafeconditions.
EAU23110
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 or
replaced at the intervals specified in the
periodic maintenance chart.
EAU23131
Checking and lubricating the
brake and shift pedals The operation of the brake and shift
pedals should be checked before each
ride, and the pedal pivots should be lu-
bricated if necessary.
Recommended lubricant:

Checking and lubricating the
sidestand The operation of the sidestand should
be checked before each ride, and the
sidestand pivot and metal-to-metal
contact surfaces should be lubricated if
necessary.
WARNING
EWA10730
If the sidestand does not move up
and down smoothly, have a Yamahadealer check or repair it.
EAU23271
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
WARNING
EWA10750
Securely support the vehicle so thatthere is no danger of it falling over.
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.
2. While applying the front brake,
push down hard on the handlebars
several times to check if the front
fork compresses and rebounds
smoothly.
CAUTION:
ECA10590
If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or re-pair it.
Recommended lubricant:
Lithium-soap-based grease (all-pur-
pose grease)
