EAU01501*Air filter
The air filter should be cleaned at
the specified intervals. It should be
cleaned more frequently when rid-
ing in unusually wet or dusty
areas.
Air filter element cleaning
1. Remove panel A. (See page
6-6 for removal and installa-
tion procedures.)
2. Remove the air filter case fit-
ting screws and the filter case
cover.

8Do not put in any chemical
additives. Engine oil also lubri-
cates the clutch and additives
could cause clutch slippage.
8Be sure no foreign material
enters the crankcase.
10. Start the engine and warm up
for a few minutes. While
warming up, check for oil leak-
age. If oil leakage is found,
stop the engine immediately
and check for the cause.

4. Remove the air filter element
from its frame and clean it
with solvent. After cleaning,
remove the remaining solvent
by squeezing the element.
5. Apply recommended oil to the
entire surface of the element
and squeeze out the excess oil.
The element should be wet but
not dripping.

8Make sure the air filter is prop-
erly seated in the air filter
case.
8The engine should never be
run without the air filter
installed. Excessive piston
and/or cylinder wear may
result.
Air filter case drain hose cleaning
Frequently check the hose at the
bottom of the air filter case. If dirt
or water is visible, remove and
clean the hose, then reinstall it.

Too little chain slack will overload
the engine and other vital parts.
Keep the slack within the specified
limits.
4. Tighten the wheel axle nut to
the specified torque.
5. Adjust the brake pedal free

EAU01106*Drive chain lubrication
The chain consists of many parts
which work with each other. If the
chain is not maintained properly, it
will wear out quickly. Therefore,
the chain must be serviced regular-
ly. This service is especially neces-
sary when riding in dusty areas.
The drive chain should be lubri-
cated every 500 km. First, remove
all dirt and mud from the chain
with a brush or cloth. Then, spray
any of the many brands of spray-
type chain lubricant between
both rows of side plates and on
all center rollers.
To clean the chain thoroughly,
remove it from the motorcycle,
dip it in solvent, and clean out as
much dirt as possible. Then, take
the chain out of the solvent to
dry it, and immediately lubricate
it to prevent it from rusting.

Be sure to oil the chain after wash-
ing the motorcycle or riding in the
rain.

EAU02962Cable inspection and
lubrication
EW000112
w
Damage to the outer housing of
cables may lead to internal rusting
and interfere with the cable move-
ment. Replace damaged cables as
soon as possible to prevent unsafe
conditions.
Lubricate the cables and cable
ends. If a cable does not operate
smoothly, ask a Yamaha dealer to
replace it.EAU00773Throttle cable and grip
lubrication
The throttle twist grip assembly
should be greased at the time that
the cable is lubricated, since the
grip must be removed to get at the
end of the throttle cable. After
removing the screws, hold the end
of the cable up in the air and put in
several drops of lubricant. With the
throttle grip disassembled, coat the
metal surface of the grip assembly
with a suitable all-purpose grease. Recommended lubricant:

Storage
Short-term
Always store your motorcycle in a
cool, dry place and, if necessary,
protect it against dust with a
porous cover.
ECA00014
cC
8Storing 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 chem-
icals are stored.
Long-term
Before storing your motorcycle for
several months:
1. Follow all the instructions in
the “Care” section of this
chapter.
2. Drain the carburetor float
chamber by loosening the
drain bolt; this will prevent fuel
deposits from building up.
Pour the drained fuel into the
fuel tank.
3. Only for motorcycles equipped
with a fuel cock which has an
“OFF” position: Turn the fuel
cock to “OFF”.
4. Fill up the fuel tank and add
fuel stabilizer (if available) to
prevent the fuel tank from rust-
ing and the fuel from deterio-
rating.
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 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, install the
spark plug and then the spark
plug cap.
EWA00003
w
When turning the engine over, be
sure to ground the spark plug elec-
trodes to prevent damage or injury
from sparking.
6. Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.

Be sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled “Energy
Conserving”) contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting in reduced
component life and poor engine performance.
