610. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
TIPAfter the engine is started, the engine
oil level warning light should go off if
the oil level is sufficient.NOTICE
ECA10402
If the oil level warnin g lig ht flickers
or remains on even if the oil level is
correct, imme diately turn the en gine
off an d have a Yamaha d ealer check
the vehicle.11. Turn the engine off, wait a few minutes until the oil settles, and
then check the oil level and cor-
rect it if necessary.
12. Install the cowling.

CoolantThe coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU46804
To check the coolant level 1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.TIPThe coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
 Make sure that the vehicle is posi-
tioned 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.TIPThe coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below theminimum level mark, remove the
coolant reservoir breather hose
from the guide, and then remove
the coolant reservoir cap.
WARNING! Remove only the
coolant reservoir cap. Never at-
tempt to remove the ra diator
cap when the en gine is hot.

mark, and then install the coolant
reservoir cap. NOTICE: If coolant
is not availa ble, use d istilled wa-
ter or soft tap water instea d. Do
not use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protected against frost an d
corrosion. If water has been
a dde d to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as soon as possi
ble, otherwise the
effectiveness of the coolant will
b e red uced.

To chan ge the coolant
1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Remove cowling A and panel B. (See page 6-8.) 3. Place a container under the en-
gine to collect the used coolant.
4. Remove the radiator cap retaining bolt, radiator cap retainer and ra-
diator cap. WARNING! Never at-
tempt to remove the ra diator

TiresTires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.

proper tire pressure may cause se-
vere injury or death from loss of
control.  The tire air pressure must be

Supporting the motorcycleSince this model is not equipped with a
centerstand, follow these precautions
when removing the front and rear
wheel or performing other mainte-
nance requiring the motorcycle to
stand upright. Check that the motorcy-
cle is in a stable and level position be-
fore starting any maintenance. A
strong wooden box can be placed un-
der the engine for added stability.
To service the front wheel
1. Stabilize the rear of the motorcy- cle by using a motorcycle stand
or, if an additional motorcycle
stand is not available, by placing a
jack under the frame in front of the
rear wheel.
2. Raise the front wheel off the ground by using a motorcycle
stand.
To service the rear wheel
Raise the rear wheel off the ground by
using a motorcycle stand or, if a motor-
cycle stand is not available, by placing a jack either under each side of the
frame in front of the rear wheel or under
each side of the swingarm.
