63. Wait a few minutes until the oil
settles, and then check the oil
level through the check window
located at the right side of the
crankcase.
NOTE:
The transmission oil should be at or
above the minimum level mark.4. If the oil is below the minimum
level mark, remove the oil filler
cap, add sufficient oil of the rec-
ommended type to raise it to the
correct level, and then install and
tighten the cap.To change the transmission oil
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the trans-
mission to collect the used oil.
3. Remove the oil filler cap and
drain bolt to drain the oil from the
transmission.4. Install the transmission oil drain
bolt, and then tighten it to the
specified torque.
5. Add the specified amount of the
recommended transmission oil,
and then install and tighten the
oil filler cap.

cC8In order to prevent clutch slip-
page (since the transmission
oil also lubricates the clutch),
do not mix any chemical addi-
tives with the oil.
8Make sure that no foreign
material enters the transmis-
sion.6. Start the engine, and then let it
idle for several minutes while
checking the transmission for oil
leakage. If oil is leaking, immedi-
ately turn off the engine and
check for the cause.

CoolantTo check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:
8The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
8Make sure that the motorcycle is
positioned 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
coolant reservoir.NOTE:
The coolant should be between the
minimum and maximum level marks.3. If the coolant is at or below the
minimum level mark, open the
reservoir cap, add coolant to the
maximum level mark, and then
close the reservoir cap.

6 4. Lift the front of the fuel tank to
position the fuel tank away from
the air filter case. (Do not discon-
nect the fuel hoses!)
EW000071
w8Make sure that the fuel tank is
well supported.
8Do not tilt or pull the fuel tank
too much, otherwise the fuel
hoses may come loose, which
could cause fuel leakage.
5. Remove the relays by pulling
them off their holders, and the air
filter case cover by removing the
screws.6. Pull the sponge material out,
clean it with solvent, and then
squeeze the remaining solvent
out.
7. Apply oil of the recommended
type to the entire surface of the
sponge material, and then
squeeze the excess oil out.
NOTE:
The sponge material should be wet
but not dripping.

62. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant.
ECA00052
cCDo not use engine oil or any other
lubricants for the drive chain, as
they may contain substances that
could damage the O-rings.
EAU02962
Checking and lubricating the
cablesThe 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.
EW000112
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.

MOTORCYCLE CARE AND STORAGE

CareWhile the open design of a motorcy-
cle reveals the attractiveness of the
technology, it also makes it more vul-
nerable. Rust and corrosion can
develop even if high-quality compo-
nents are used. A rusty exhaust pipe
may go unnoticed on a car, however,
it detracts from the overall appear-
ance of a motorcycle. Frequent and
proper care does not only comply
with the terms of the warranty, but it
will also keep your motorcycle looking
good, extend its life and optimize its
performance.Before cleaning
1. Cover the muffler outlet with a
plastic bag after the engine has
cooled down.
2. Make sure that all caps and cov-
ers as well as all electrical cou-
plers and connectors, including
the spark plug cap, are tightly
installed.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such
products onto seals, gaskets,
sprockets, the drive chain and
wheel axles. Always rinse the dirt
and degreaser off with water.Cleaning
ECA00010
cC8Avoid using strong acidic
wheel cleaners, especially on
spoked wheels. If such prod-
ucts are used on hard-to-
remove dirt, do not leave the
cleaner on the affected area
any longer than instructed.
Also, thoroughly rinse the area
off with water, immediately dry
it, and then apply a corrosion
protection spray.
8Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or
sponge with mild detergent
and water to clean plastic.

MOTORCYCLE CARE AND STORAGE
7
StorageShort-term
Always store your motorcycle in a
cool, dry place and, if necessary, pro-
tect it against dust with a porous
cover.
ECA00014
cC8Storing the motorcycle in a
poorly ventilated room or cov-
ering it with a tarp, while it is
still wet, will allow water and
humidity to seep in and cause
rust.
8To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
Long-term
Before storing your motorcycle for
several months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. For motorcycles equipped with a
fuel cock that has an “OFF” posi-
tion: Turn the fuel cock lever to
“OFF”.
3. Drain the carburetor float cham-
ber by loosening the drain bolt;
this will prevent fuel deposits
from building up. Pour the
drained fuel into the fuel tank.
4. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5. Perform the following steps to
protect the cylinder, piston rings,
etc. from corrosion.a. Remove the spark plug cap
and spark plug.
b. Pour a teaspoonful of engine
oil into the spark plug bore.
c. Install the spark plug cap onto
the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes
are grounded. (This will limit
sparking during the next step.)
d. Turn the engine over several
times with the starter. (This
will coat the cylinder wall with
oil.)
e. Remove the spark plug cap
from the spark plug, and then
install the spark plug and the
spark plug cap.
EWA00003
wTo prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turn-
ing the engine over.
