OPERATION AND IMPORTANT RIDING POINTS
EAU15951
Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do not
understand, ask your Yamaha dealer.
WARNING
EWA10271
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accident
or injury.
EAU40886
Starting and warming up a
cold engine
1. Turn the fuel cock lever to “O” (on).
2. Set the engine stop switch to
“START”.
3. Turn the starter (choke) on and
completely close the throttle. (See
page 3-6.)
4. While applying the front or rear
brake, start the engine by pushing
the kickstarter lever down.
5. After starting the engine, move the
starter (choke) back halfway.
NOTICE:
For maximum engine
life, always warm the engine up
before starting off. Never accel-
erate hard when the engine is
cold!
[ECA11131]
6. When the engine is warm, turn the
starter (choke) off and set the en-
gine stop switch to “RUN”.
TIP
The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off.
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.
TIP
If the engine does not start after sever-
al kicks, try again with the throttle 1/4
to 1/2 open.

Starting off
TIP
Before starting off, allow the engine to
warm up.
1. While applying the rear brake le-
ver, push the motorcycle off the
centerstand.
2. Completely close the throttle.
3. Set the engine stop switch to
“RUN”.
4. Check for oncoming off-road vehi-
cles, and then slowly turn the throt-
tle grip in order to take off.
EAU16780
Acceleration and deceleration
The speed can be adjusted by opening
and closing the throttle. To increase the
speed, turn the throttle grip in direction
(a). To reduce the speed, turn the throt-
tle grip in direction (b).
EAU41012
Braking
WARNING
EWA14571
Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the motor-
cycle may skid or overturn.
Keep in mind that braking on
wet surfaces is much more diffi-
cult.
Ride slowly down a hill, as brak-
ing downhill can be very diffi-
cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.

Engine break-in
There is never a more important period
in the life of your engine than the first 5
hours of riding. It is also important to ac-
custom the rider to the motorcycle dur-
ing this time. Please read the following
information carefully.
Since the engine is brand new, do not
put an excessive load on it for the first 5
hours of operation. The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided. However, momentary
full-throttle operation under load (i.e.,
two to three seconds maximum) does
not harm the engine. Each full-throttle
acceleration should be followed with a
substantial rest period for the engine.
To allow the engine to cool down from
the temporary buildup of heat, cruise at
a lower engine speed.
After the first 5 hours of operation, thor-
oughly check the motorcycle for loose
parts, oil leakage and any other prob-
lems. Be sure to inspect and make ad-justments thoroughly, especially
cables. In addition, check all fittings and
fasteners for looseness, and tighten if
necessary.
NOTICE
ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

Parking
When parking, stop the engine, and
then turn the fuel cock lever to “S”
(stop).
WARNING
EWA10311
Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them and be burned.
Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn, increasing the
risk of a fuel leak and fire.
Do not park near grass or other
flammable materials which
might catch fire.

PERIODIC MAINTENANCE AND ADJUSTMENT
EAU41951
Periodic inspection, adjustment, and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. Safety is an obligation of the vehi-
cle owner/operator. The most important
points of vehicle inspection, adjust-
ment, and lubrication are explained on
the following pages.
WARNING
EWA10321
Failure to properly maintain the ve-
hicle or performing maintenance ac-
tivities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha dealer perform
service.
WARNING
EWA15121
Turn off the engine when performing
maintenance unless otherwise
specified.
A running engine has moving
parts that can catch on body
parts or clothing and electricalparts that can cause shocks or
fires.
Running the engine while ser-
vicing can lead to eye injury,
burns, fire, or carbon monoxide
poisoning – possibly leading to
death. See page 1-1 for more in-
formation about carbon monox-
ide.
EAU17311

TIP
If you do not have the tools or experi-
ence required for a particular job, have
a Yamaha dealer perform it for you.
