Speed limiter Your motorcycle was delivered with an
adjustable speed limiter. The speed
limiter keeps the throttle from fully
opening, even when the throttle grip is
turned to the maximum.
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.
WARNING
EWA14400
Improper adjustment of the speed
limiter and throttle could cause
throttle cable damage or improper
throttle operation. You could lose
control, have an accident or be in-
jured. Do not turn the adjusting
screw out more than 25 mm (0.98 in)
or the throttle cable could be dam-
aged. Always make sure the throttle
cable free play is adjusted to 3.0–5.0mm (0.12–0.20 in). (See page 6-11.)

Fuel Make sure that there is sufficient fuel in
the tank. Fill the fuel tank to the bottom
of the filler tube as shown.
WARNING
EWA10880


Do not overfill the fuel tank, oth-
erwise it may overflow when the
fuel warms up and expands.


Avoid spilling fuel on the hot en-gine.
CAUTION:
ECA10070
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since
fuel may deteriorate painted surfac-es or plastic parts.
EAU41930
For CanadaCAUTION:
ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,as well as to the exhaust system.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a pump octane number[(R+M)/2] of 86 or higher, or a research
octane number of 91 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 cost.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that contain-
ing methanol. Gasohol containing
ethanol can be used if ethanol content
does not exceed 10%. Gasohol con-
taining methanol is not recommended
by Yamaha because it can cause dam-
age to the fuel system or vehicle perfor-
mance problems.
