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.
NOTICE
ECA11230
After changing the engine oil, make
sure to check the oil pressure as de-
scribed below.
Remove the bleed bolt.
Start the engine and keep itidling until oil flows out. If no oil
comes out after one minute,
turn the engine off immediately
so it will not seize. If this occurs,
have a Yamaha dealer repair the
vehicle.
After checking the oil pressure,
tighten the bleed bolt to the
specified torque.

Coolant
The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU20253
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
TIP
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.

5. Apply oil of the recommended type
to the entire surface of the sponge
material, and then squeeze the ex-
cess oil out.
TIP
The sponge material should be wet but
not dripping.
6. Pull the sponge material over the
air filter element frame.
7. 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.

8. Place the holding clip in the origi-
nal position.
9. Close the air filter case cover, and
then install the screw.
10. Install the panel.
To clean the air filter check hose
1. Check the hose at the bottom of
the air filter case for accumulated
dirt or water.2. If dirt or water is visible, remove
the hose, clean it, and then install
it.

Adjusting the engine idling
speed
The engine idling speed must be
checked and, if necessary, adjusted as
follows.
TIP
A digital tachometer is needed to make
this adjustment.
1. Position the digital tachometer at
the ignition coil, which is located in
the spark plug cap.
2. Check the engine idling speed
and, if necessary, adjust it to spec-
ification by turning the idle adjust-
ing screw. To increase the engine
idling speed, turn the screw in di-
rection (a). To decrease the en-
gine idling speed, turn the screw in
direction (b).
TIP
If the specified idling speed cannot be
obtained as described above, have a
Yamaha dealer make the adjustment.

sary, have a Yamaha dealer adjust it.

Checking the brake fluid level
Front brake
Rear brake
Insufficient brake fluid may allow air toenter the brake system, possibly caus-
ing it to become ineffective.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake fluid
level may indicate worn brake pads
and/or brake system leakage. If the
brake fluid level is low, be sure to check
the brake pads for wear and the brake
system for leakage.
Observe these precautions:
When checking the fluid level,
make sure that the top of the brake
fluid reservoir is level.
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 brake fluid reservoir whenrefilling. 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 the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.

Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenance
and lubrication chart. In addition, have
the oil seals of the master cylinders and
calipers as well as the brake hoses re-
placed at the intervals listed below or
whenever they are damaged or leak-
ing.
Oil seals: Replace every two
years.
Brake hoses: Replace every four
years.

Drive chain slack
The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU47221
To check the drive chain slack
1. Place the motorcycle on the side-
stand.
TIP
When checking and adjusting the drive
chain slack, there should be no weight
on the motorcycle.
2. Shift the transmission into the neu-
tral position.
3. Push on the drive chain at the cen-
ter point between the chain ten-
sioner and the chain support
mounting bolt with a force of 50 N
(5.0 kgf, 36 lbf).
4. Measure drive chain slack be-
tween the swingarm and the top of
the chain link closest to the swing-
arm as shown.5. If the drive chain slack is incorrect,
adjust it as follows.
EAU22943
To adjust the drive chain slack
1. Loosen the axle nut and the lock-
nut on each side of the swingarm.
2. To tighten the drive chain, turn the
drive chain slack adjusting bolt on
each side of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting bolt on each side
of the swingarm in direction (b),
and then push the rear wheel for-
ward.

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
sheath may interfere with proper ca-
ble operation and will cause the in-
ner cable to rust. Replace a
damaged cable as soon as possible
to prevent unsafe conditions.

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

suspension
The pivoting points of the rear suspen-
sion must be lubricated at the intervals
specified in the periodic maintenance

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.
