before starting off. Set this switch to
“OFF” to stop the engine.
TIP
 The engine cannot be started with
this switch set to the “RUN” posi-
tion.
 The engine speed is limited while
this switch is set to the “START”
position, therefore the motorcycle
cannot be ridden in that switch
position.

Spee d limiter an d power re-
d uction plate
Your motorcycle is equipped with an
adjustable speed limiter and a power
reduction plate. The speed limiter
keeps the throttle from fully opening,
even when the throttle grip is turned to
the maximum. The power reduction
plate is installed in the exhaust mani-
fold to limit the amount of power avail-
able while learning.
Speed limiter
1. Loosen the locknut.
2. To increase the maximum engine power available and the maximum
speed of the motorcycle, turn the
adjusting screw in direction (a). To
decrease the maximum engine
power available and the maximum
speed of the motorcycle, turn the
adjusting screw in direction (b).
3. Tighten the locknut.

TIP
The adjusting range of the speed limit-
er screw is from the fully turned-in po-
sition to 7 mm (0.28 in) turned out.
When the screw is turned out to 7 mm
(0.28 in), the throttle grip can only be
opened approximately halfway. If more
power is required, please consult a
Yamaha dealer.
WARNING
EWA14632
Improper a djustment of the speed
limiter coul d cause improper throttle
operation. You coul d lose control,
have an acci dent or be injure d. Do
not turn the a djustin g screw out
more than 7 mm (0.28 in) b efore con-
sultin g a Yamaha dealer. Always
make sure the throttle g rip free play
is a djuste d to 1.5–3.5 mm (0.06–0.14
in). (See pag e 7-14.)
Power reduction plate
Once the rider can operate with skill at
the top speed permitted by adjusting
the speed limiter alone, the power re-
duction plate can be removed. (See
page 7-7.)

Fuel
Make sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline an d g asoline vapors are
extremely flamma ble. To avoi d fires
an d explosions an d to re duce the
risk of injury when refuelin g, 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 spille d fuel with a clean, d
ry, soft cloth, since fuel may
d eteriorate painte d surfaces or
plastic parts.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous an d can
cause injury or death. Han dle gaso-
line with care. Never siphon gasoline
b y mouth. If you shoul d swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some gasoline in
your eyes, see your doctor imme di-
ately. If gasoline spills on your skin,
wash with soap an d water. If gaso-
line spills on your clothin g, chan ge
your clothes.
EAU41987
NOTICE
ECA15591
Use only unlea ded g asoline. The use
of lead ed g asoline will cause severe
d amag e to internal en gine parts,
such as the piston rin gs as well as to
the exhaust system.
 For Canada: Use gasoline with a
pump octane number [(R+M)/2] of
86 or higher (research octane
number of 91 or higher).
 For Oceania and South Africa: Use
gasoline with a research octane
number of 91 or higher.


For Europe: Use gasoline with a
research octane number of 95 or
higher.
If knocking (or pinging) occurs, use a
gasoline of a different brand or premi-
um unleaded fuel. Use of unleaded fuel
will extend spark plug life and reduce
maintenance costs.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if ethanol content
does not exceed 10% (E10). Gasohol
containing methanol is not recom-
mended by Yamaha because it can
cause damage to the fuel system or
vehicle performance problems.
For Europe
TIP
 This mark identifies the recom-
mended fuel for this vehicle as
specified by European regulation
(EN228).
 Confirm the gasoline nozzle has
the same mark when fueling.

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 necessary.
 Make sure that the fuel tank
breather hose is not blocked, and
clean it if necessary.

Fuel cock
The fuel cock supplies fuel from the
tank to the carburetor while filtering it
also.
The fuel cock has two positions:
S (stop)
With the lever in this position, fuel will
not flow. Always return the lever to this
position when the engine is not run-
ning.
O (on)
With the lever in this position, fuel flows
to the carburetor. Normal riding is done
with the lever in this position.
