WARNING
EWA14610
This model is designed for off-
road use only. Become thor-
oughly familiar with all operat-
ing controls and their functions
before riding. Consult a Yamaha
dealer regarding any control or
function that you do not thor-
oughly understand.
Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
Before starting out, make sure
that the sidestand is removed. If
the sidestand is not removed, it
will contact the ground, which
could distract the operator or af-
fect the balance of the motor-
cycle, resulting in a possibleloss of control.

For maximum engine life, always
warm the engine up before starting
off. Never accelerate hard when theengine is cold!
5. When the engine is warm, turn the
starter (choke) off.NOTE:The engine is warm when it responds

EAU16660
Starting a warm engine Follow the same procedure as for start-
ing a cold engine with the exception
that the starter (choke) is not required
when the engine is warm. Instead, start
the engine with the throttle slightly
open.NOTE:If the engine does not start after several
kicks, try again with the throttle 1/4 to1/2 open.

CAUTION:
ECA10452
In order to prevent clutch slip-
page (since the transmission oil
also lubricates the clutch), do
not mix any chemical additives.
Do not use oils with a diesel
specification of “CD” or oils of a
higher quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Make sure that no foreign mate-rial enters the transmission.
7. Start the engine, and then let it idle
for several minutes while checking
the transmission for oil leakage. If
oil is leaking, immediately turn the
engine off and check for the cause.
EAU20070
Coolant The 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.
EAUM1291
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
2. Remove the radiator cap and
check the coolant level in the radi-
ator.
NOTE:
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to theside can result in a false reading.
NOTE:The coolant should be at the brim of the
radiator filler. The level will change withvariation of engine temperature.1. Radiator cap
