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.
EAU39901
Shifting This motorcycle has a 3-speed trans-
mission with a centrifugal, automatic
clutch. Shifting gears lets you control
the amount of engine power available
for starting off, accelerating, climbing
hills, etc.
The gear positions are shown in the il-
lustration.TIPTo shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of its
travel.
NOTICE
ECA15441
●
Even with the transmission in
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long dis-
tances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.
●
Always release the throttle grip
before changing gears to avoid
damaging the engine, transmis-
sion, and drive train, which are
not designed to withstand the
shock of shifting when the throt-
tle grip is open.
EAU39911
To start out and accelerate1. Close the throttle.
2. Shift into first gear and release the shift pedal. NOTICE: Always
close the throttle before shifting
gears, otherwise damage to the
engine and drive train may re-
sult.

63. Open the throttle gradually.
4. Once the motorcycle has reached
a speed high enough to change
gears, close the throttle.
5. Shift into second gear and release the shift pedal.
6. Open the throttle gradually.
7. Follow the same procedure when shifting to the next higher gear.
EAU16710
To decelerate1. Close the throttle and apply both the front and the rear brakes to
slow the motorcycle.
2. Downshift through the gears and shift the transmission into the neu-
tral position when the motorcycle
is almost completely stopped.
EAU39920
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 ac-
celeration 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 cable
and drive chain slack and loose
spokes. In addition, check all fittings
and fasteners for looseness, and tight-
en 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, remove
the key from the main switch, and then
turn the fuel cock lever to “OFF”.
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

EAU17244
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.
The intervals given in the periodic
maintenance charts should be simply
considered as a general guide under
normal riding conditions. However, de-
pending on the weather, terrain, geo-
graphical location, and individual use,
the maintenance intervals may need to
be shortened.
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
EWA15122
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 electrical
parts 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 2-2 for more in-
formation about carbon monox-
ide.WARNING
EWA15460
Brake discs, calipers, drums, and
linings can become very hot during
use. To avoid possible burns, let
brake components cool before
touching them.
EAU17302
Emission controls not only function to
ensure cleaner air, but are also vital to
proper engine operation and maximum
performance. In the following periodic
maintenance charts, the services relat-
ed to emissions control are grouped
separately. These services require
specialized data, knowledge, and
equipment. Maintenance, replacement,
or repair of the emission control devic-
es and systems may be performed by
any repair establishment or individual
that is certified (if applicable). Yamaha
dealers are trained and equipped to
perform these particular services.
