SAFETY INFORMATION

Never install accessories that
would impair the performance of
your motorcycle. Carefully inspect
the accessory before using it to
make sure that it does not in any
way reduce ground clearance or
cornering clearance, limit suspen-
sion travel, steering travel or con-
trol operation.
Accessories fitted to the handle-
bar or the front fork area can
create instability due to improper
weight distribution. If accesso-
ries are added to the handlebar
or front fork area, they must be
as lightweight as possible and
should be kept to a minimum.
Bulky or large accessories may
seriously affect the stability of
the motorcycle. Wind may at-
tempt to lift the motorcycle, or
the motorcycle may become un-
stable in cross winds.
Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the free-
dom of movement of the opera-tor and may limit control ability,
therefore, such accessories are
not recommended.


Use caution when adding electri-
cal accessories. If electrical acces-
sories exceed the capacity of the
motorcycle’s electrical system, an
electric failure could result, which
could cause a dangerous loss of
lights or engine power.
Aftermarket Tires and Rims
The tires and rims that came with your
motorcycle were designed to match the
performance capabilities and to provide
the best combination of handling, brak-
ing, and comfort. Other tires, rims, siz-
es, and combinations may not be
appropriate. Refer to page 7-13 for tire
specifications and more information on
replacing your tires.
Transporting the motorcycle
Be sure to observe following instruc-
tions before transporting the motorcy-
cle in another vehicle.


Remove all loose items from the
motorcycle.


Check that the fuel cock (if
equipped) is in the “OFF” position
and that there are no fuel leaks.


Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.


Shift the transmission in gear (for
models with a manual transmis-
sion).


Secure the motorcycle with tie-
downs or suitable straps that are
attached to solid parts of the mo-
torcycle, such as the frame or up-
per front fork triple clamp (and not,
for example, to rubber-mounted
handlebars or turn signals, or parts
that could break). Choose the lo-
cation for the straps carefully so
the straps will not rub against
painted surfaces during transport.


The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the mo-
torcycle will not bounce excessive-
ly during transport.

Fuel Make sure there is sufficient gasoline in
the tank.
WARNING
EWA10881
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.1. Before refueling, turn off the en-
gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters and
clothes dryers.
2. Do not overfill the fuel tank. Stop
filling when the fuel reaches the
bottom of the filler tube. Because
fuel expands when it heats up,
heat from the engine or the sun
can cause fuel to spill out of the
fuel tank.3. Wipe up any spilled fuel immedi-
ately. NOTICE: Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may deteri-
orate painted surfaces or plastic
parts.
[ECA10071]
4. Be sure to securely close the fuel
tank cap.
WARNING
EWA15151
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some gasoline in
your eyes, see your doctor immedi-ately. If gasoline spills on your skin,
wash with soap and water. If gaso-
line spills on your clothing, change
your clothes.

NOTICE

Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the piston rings as well as to
the exhaust system.Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging) oc-

or premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.

Fuel tank breather hose Before operating the motorcycle:

Check the fuel tank breather hose
connection.


Check the fuel tank breather hose
for cracks or damage, and replace
it if damaged.


Make sure that the fuel tank
breather hose is not blocked, and
clean it if necessary.
EAU41202
2-stroke engine oil Make sure that there is sufficient oil in
the 2-stroke engine oil tank. If the 2-
stroke engine oil is at or below the min-
imum level as shown in the illustration,
add a sufficient amount of the recom-
mended 2-stroke engine oil as follows.TIPMake sure that the motorcycle is posi-
tioned straight up when checking the 2-
stroke engine oil level. A slight tilt to the
side can result in a false reading.1. Remove the seat. (See page 4-7.)
2. Remove the 2-stroke engine oil
tank cap and add the recommend-
ed oil.

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.TIPIf the engine does not start after several
kicks, try again with the throttle 1/4 to
1/2 open.
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 accelerate
1. 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.

Checking the spark plug The spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plug should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plug can re-
veal the condition of the engine.
To remove the spark plug
1. Remove the spark plug cap.
2. Remove the spark plug as shown,
with the spark plug wrench includ-
ed in the owner’s tool kit.To check the spark plug
1. Check that the porcelain insulator
around the center electrode of the
spark plug is a medium-to-light tan
(the ideal color when the vehicle is
ridden normally).
TIPIf the spark plug shows a distinctly dif-
ferent color, the engine could be oper-
ating improperly. Do not attempt to
diagnose such problems yourself. In-
stead, have a Yamaha dealer check
the vehicle.
2. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if
necessary.
3. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
