Sidestand
The sidestand is located on the left
side of the frame. Raise the side-
stand or lower it with your foot while
holding the motorcycle upright.
NOTE:
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situ-
ations. (See further down for an
explanation of the ignition circuit cut-
off system.)
EW000044
w
The motorcycle must not be ridden
with the sidestand down, or if the
sidestand cannot be properly
moved up (or does not stay up),
otherwise the sidestand could con-
tact the ground and distract the
operator, resulting in a possible
loss of control. Yamaha’s ignition
circuit cut-off system has been
designed to assist the operator in
fulfilling the responsibility of rais-
ing the sidestand before starting
off. Therefore, check this system
regularly as described below and
have a Yamaha dealer repair it if it
does not function properly.
EAU00331
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch,
clutch switch and neutral switch) has
the following functions.
8It prevents starting when the
transmission is in gear and the
sidestand is up, but the clutch
lever is not pulled.
8It prevents starting when the
transmission is in gear and the
clutch lever is pulled, but the
sidestand is still down.
8It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.

w
If a malfunction is noted, have a
Yamaha dealer check the system
before riding.

The condition of a vehicle is the ownerís responsibility. Vital components can start to deteriorate quickly and unexpect-
edly, even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leak-
age or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thor-
ough visual inspection, to check the following points before each ride.

4. Turn the starter (choke) on and
completely close the throttle.
(See page 3-8 for starter (choke)
operation.)
5. Start the engine by pushing the
start switch.
NOTE:
If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the
engine more than 10 seconds on any
one attempt.
ECA00059
cC
If the oil level warning light flickers
or remains on after starting, imme-
diately stop the engine, and then
check the engine oil level and the
vehicle for oil leakage. If neces-
sary, add engine oil, and then
check the warning light again. If
the warning light does not go off
after starting with sufficient engine
oil, have a Yamaha dealer check
the electrical circuit.
6. After starting the engine, move
the starter (choke) lever back
halfway.
ECA00055
cC
For maximum engine life, always
warm the engine up before starting
off. Never accelerate hard when
the engine is cold.
7. When the engine is warm, turn
the starter (choke) off.
NOTE:
The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off.

Adjusting the engine idling
speed
The engine idling speed must be
checked and, if necessary, adjusted
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.
NOTE:
A diagnostic tachometer is needed to
make this adjustment.
1. Attach the tachometer to the
spark plug lead.
2. Start the engine and warm it up
for several minutes at 1,000–
2,000 r/min while occasionally
revving it to 4,000–5,000 r/min.
NOTE:
The engine is warm when it quickly
responds to the throttle.

8Make sure that the air filter ele-
ment is properly seated in the
air filter case.
8The engine should never be
operated without the air filter
element installed, otherwise
the piston(s) and/or cylinder(s)
may become excessively
worn.
6. Install the air filter case cover by
installing the screws.
7. Install the air filter case by
installing the bolts and tightening
the clamp screw.
EAU00629
Adjusting the carburetor
The carburetor is an important part of
the engine and requires very sophisti-
cated adjustment. Therefore, most
carburetor adjustments should be left
to a Yamaha dealer, who has the
necessary professional knowledge
and experience. The adjustment
described in the following section,
however, may be serviced by the
owner as part of routine mainte-
nance.
EC000094
cC
The carburetor has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine.

PERIODIC MAINTENANCE AND MINOR REPAIR
EAU03006
Lubricating the drive chain
The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly
wear out, especially when riding in
dusty or wet areas. Service the drive
chain as follows.
EC000097
cC
The drive chain must be lubricated
after washing the motorcycle or
riding in the rain.
1. Clean the drive chain with
kerosene and a small soft brush.
ECA00053
cC
To prevent damaging the O-rings,
do not clean the drive chain with
steam cleaners, high-pressure
washers or inappropriate solvents.
EC000096
cC
Improper drive chain slack will
overload the engine as well as
other vital parts of the motorcycle
and can lead to chain slippage or
breakage. To prevent this from
occurring, keep the drive chain
slack within the specified limits.
3. Tighten both locknuts, and then
tighten the axle nut to the speci-
fied torque.
4. Adjust the brake pedal free play.
(See page 6-22 for brake pedal
free play adjustment proce-
dures.)
EW000103
w
After adjusting the brake pedal
free play, check the operation of
the brake light.
Tightening torque:
Axle nut:
104 Nm (10.4 m·kg)
2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant.
ECA00052
cC
Do not use engine oil or any other
lubricants for the drive chain, as
they may contain substances that
could damage the O-rings.

MOTORCYCLE CARE AND STORAGE
Care
While 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 outlets with
plastic bags 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 caps, 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.CleaningECA00010
cC
8Avoid 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.
