Catalytic converter This vehicle is equipped with a catalytic
converter in the muffler.
WARNING
EWA10860
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-ing any maintenance work.CAUTION:
ECA10700
The following precautions must be
observed to prevent a fire hazard or
other damages.
Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.
Never park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.
Do not allow the engine to idletoo long.
EAU13570
Fuel cock The fuel cock supplies fuel from the
tank to the carburetors while also filter-
ing it.
The fuel cock lever positions are ex-
plained as follows and shown in the il-
lustrations.
ON
With the fuel cock lever in this position,
fuel flows to the carburetors when the
engine is running. Turn the fuel cock le-
ver to this position when starting the en-
gine and riding.RES
This indicates reserve. With the fuel
cock lever in this position, the fuel re-
serve is made available. Quickly turn
the fuel cock lever to this position if you
run out of fuel while riding, otherwise
the engine may stall and will have to be
primed (see “PRI”). After turning the
fuel cock lever to “RES”, refuel as soon
as possible and be sure to turn the fuel
cock lever back to “ON”!1. Arrow mark positioned over “ON”

The annual checks must be performed every year, except if a kilometer-based maintenance is performed in-
stead.
From 50000 km, repeat the maintenance intervals starting from 10000 km.
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and technicalskills.

NOTE:
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
Hydraulic brake and clutch service
Regularly check and, if necessary, correct the brake and clutch fluid levels.
Every two years replace the internal components of the brake master cylinders and calipers as well as clutch master
and release cylinders, and change the brake and clutch fluids.Replace the brake and clutch hoses every four years and if cracked or damaged.

gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then tight-
en it to the specified torque.
NOTE:
If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-fied torque as soon as possible.
4. Install the spark plug cap.

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 ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Place the vehicle on the center-
stand.NOTE:
Make sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in afalse reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Wait a few minutes until the oil set-
tles, and then check the oil level
through the check window located
at the bottom-right side of the
crankcase.
NOTE:The engine oil should be between theminimum 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 replace-
ment)
1. Start the engine, warm it up for
several minutes, and then turn it
off.

to collect the used oil.
3. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.
NOTE:
Skip steps 4–10 if the oil filter elementis not being replaced.
4. Remove panel C. (See page 6-5.)
5. Remove the oil filter element drain
screw to drain the oil from the oil fil-
ter element.
6. Remove the oil filter element cover
by removing the bolt.7. Remove and replace the oil filter
element and O-ring.8. Install the oil filter element cover by
aligning the projection on the cover
with the slot in the crankcase, in-
stalling the bolt, then tightening it
to the specified torque.
NOTE:Make sure that the O-ring is properlyseated.

screw, and then tighten it to the
specified torque.

12. Add the specified amount of the
recommended engine oil, and then
install and tighten the oil filler cap.
CAUTION:
ECA11620
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do notmix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Make sure that no foreign mate-rial enters the crankcase.
13. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
NOTE:After the engine is started, the engine
oil level warning light should go off if theoil level is sufficient.CAUTION:
ECA10400
If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha dealercheck the vehicle.
14. Turn the engine off, and then
check the oil level and correct it if
necessary.

Cleaning the air filter element The air filter element should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
Clean the air filter element more fre-
quently if you are riding in unusually
wet or dusty areas.
1. Remove the seat. (See page
3-14.)
2. Remove panel A. (See page 6-5.)
3. Remove the air filter case cover by
removing the screws.
4. Pull the air filter element out.
