crankcase.
NOTE:
The engine oil should be between the
minimum and maximum level marks.
4. If the engine oil is below the mini-
mum 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 cleaning)
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engineto collect the used oil.
3. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.
CAUTION:
ECA11000
When removing the engine oil drain
bolt, the O-ring, compression
spring, and oil strainer will fall out.
Take care not to lose these parts.

4. Remove the sponge material from
the air filter element frame, clean it
with solvent, and then squeeze the
remaining solvent out.
5. Apply oil of the recommended type
to the entire surface of the spongematerial, and then squeeze the ex-
cess oil out.
NOTE:
The sponge material should be wet but
not dripping.
6. Pull the sponge material over the
air filter element frame.
7. Insert the element into the air filter
case.
CAUTION:
ECA10480
Make sure that the air filter ele-
ment is properly 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. Install the air filter case cover by in-
stalling the screws.
9. 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.

peared, have a Yamaha dealer replace

Rear brake shoes
The rear brake is provided with a wear
indicator, which allows you to check the
brake shoe wear without having to dis-
assemble the brake. To check the
brake shoe wear, check the position of
the wear indicator while applying the
brake. If a brake shoe has worn to the
point that the wear indicator reaches
the wear limit line, have a Yamaha
dealer replace the brake shoes as a
set.
EAU32341
Checking the brake fluid level
Front brake
Insufficient brake fluid may allow air to
enter 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 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 the

Lubricating the drive chain
The drive chain must be cleaned and
lubricated at the intervals specified in
the General 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.
CAUTION:
ECA10580
The drive chain must be lubricated
after washing the motorcycle or
riding in the rain.
1. Remove all dirt and mud from the
drive chain with a brush or cloth.
NOTE:
For a thorough cleaning, have a Yama-
ha 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 both sides
and on the middle of the chain,
making sure that all side plates
and rollers have been sufficientlyoiled.
EAU23100
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 unsafe
conditions.
