Engine oil and oil filter
elementEngine oil and oil filter elementThe engine oil level should be
checked before each ride. In addition,
the oil must be changed and the oil
filter element replaced at the intervals
specified in the periodic maintenance
and lubrication chart.
To check the engine oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:
Make sure that the motorcycle is
positioned straight up when checking
the oil level. A slight tilt to the side
can result in a false reading.
4. Wait a few minutes until the oil
settles, remove the oil filler cap,
wipe the dipstick clean, insert it
back into the oil filler hole (with-
out screwing it in), and then
remove it again to check the oil
level.NOTE:
The engine oil should be between the
minimum and maximum level marks.

cCAfter changing the engine oil, be
sure to check the oil pressure as
described below.11. Remove the air bleed screw, and
then start the engine. If oil does
not seep out of the hole after a
few minutes, immediately stop
the engine and have a Yamaha
dealer check for the cause. If oil
seeps out of the hole, turn the
engine off and install the air
bleed screw.12. Start the engine, and then let it
idle for several minutes while
checking it for oil leakage. If oil is
leaking, immediately turn the
engine off and check for the
cause.
13. Turn the engine off, and then
check the oil level and correct it if
necessary.

cleaned at the intervals specified in
the periodic maintenance and lubrica-

more frequently if you are riding in
unusually wet or dusty areas.
1. Remove panel B. (See page 6-8
for panel removal and installation
procedures.)
2. Remove the air filter case cover
by removing the screws, and
then pull the air filter element
out.

6 Observe these precautions:
8When checking the fluid level,
make sure that the top of the
brake fluid reservoir is level.
8Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing leakage and poor braking
performance.8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.
8Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
EAU03976
Changing the brake fluidBrake fluid, changingHave a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addi-
tion, have the oil seals of the master
cylinders and calipers as well as the
brake hoses replaced at the intervals
listed below or whenever they are
damaged or leaking.
8Oil seals: Replace every two
years.
8Brake hoses: Replace every four
years.

Checking and lubricating the
cablesCables, checking and lubricatingThe operation of all control cables
and the condition of the cables
should be checked before each ride,
and the cables and cable ends
should be lubricated if necessary. If a
cable is damaged or does not move
smoothly, have a Yamaha dealer
check or replace it.

should be checked before each ride.
In addition, the cable should be lubri-
cated or replaced at the intervals
specified in the periodic maintenance
chart.

wDamage to the outer sheath may
interfere with proper cable opera-
tion and will cause the inner cable
to rust. Replace a damaged cable
as soon as possible to prevent
unsafe conditions.
