PERIODIC MAINTENANCE AND MINOR REPAIR
EAU17240
Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in the
safest and most efficient condition
possible. The most important points of
inspection, adjustment, and lubrica-
tion are explained on the following
pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, DEPENDING ON
THE WEATHER, TERRAIN, GEO-
GRAPHICAL LOCATION, AND INDI-
VIDUAL USE, THE MAINTENANCE
INTERVALS MAY NEED TO BE
SHORTENED.
EWA10320
WARNING0
If you are not familiar with motorcy-
cle maintenance work, have a
Yamaha dealer do it for you.

Engine oil and oil filter
element
The engine oil level should be checked
before each ride. In addition, the oil must
be changed and the oil filter element re-
placed at the intervals specified in the pe-
riodic maintenance and lubrication chart.To check the engine oil level
1. Place the vehicle on a level surface
and hold it in an upright position.NOTE:
Make sure that the vehicle is posi-
tioned straight up when checking the
oil level. A slight tilt to the side can re-
sult in a false reading.
2. Start the engine, warm it up for
10-15 minutes, let it continue to
idle for 20-30 seconds, and then
turn it off.
3. 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 (without
screwing it in), and then remove it
again to check the oil level.
1. Engine oil filler cap
2. Maximum level mark
3. Minimum level mark

WARNING0
The exhaust pipes are very hot dur-
ing and following operation. To pre-
vent burns when removing the oil
filler cap, use extra care not to
touch the exhaust pipes.
NOTE:
●The engine oil tank is located in
front of the frame.
●The engine oil should be between
the minimum and maximum level
marks.

Tires
To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points regard-
ing the specified tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
EWA10500
WARNING0
●The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the tempera-
ture of the tires equals the am-
bient temperature).
●The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passenger,
cargo, and accessories ap-
proved for this model.
EWA11020
WARNING0
Because loading has an enormous
impact on the handling, braking,
performance and safety character-
istics of your motorcycle, you
should keep the following precau-
tions in mind.
●NEVER OVERLOAD THE MO-
TORCYCLE! Operation of an
overloaded motorcycle may re-
sult in tire damage, loss of con-
trol, or severe injury. Make sure
that the total weight of rider,
passenger, cargo, and acces-
sories does not exceed the
specified maximum load for the
vehicle.
●Do not carry along loosely
packed items, which can shift
during a ride.
●Securely pack the heaviest
items close to the center of the
motorcycle and distribute the
weight evenly on both sides.

PERIODIC MAINTENANCE AND MINOR REPAIR
●Adjust the suspension and tire
air pressure with regard to the
load.
●Check the tire condition and air
pressure before each ride.Tire inspection
1. Tire sidewall
2. Tire tread depth
The tires must be checked before
each ride. If the center tread depth
reaches the specified limit, if the tire
has a nail or glass fragments in it, or if
the sidewall is cracked, have a Yama-
ha dealer replace the tire immediately.
NOTE:
The tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.
EWA10470
WARNING0
●Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the ve-
hicle with excessively worn
tires decreases riding stability
and can lead to loss of control.
●The replacement of all wheel
and brake related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience.
