Filling the fuel tank
CAUTION:
Be careful when refueling. Avoid getting
water or other contaminants in the fuel
tank. Contaminated fuel can cause poor
running or engine damage.
1. Remove the rear and front seats. (See
pages 2-4 to 2-5 for seat removal and
installation procedures.)
2. Open the fuel tank filler cap, and slowly
add fuel to the fuel tank.
3. Stop filling when the fuel just reaches the
top of the fuel tank visible under the
engine oil tank.
NOTE:
●The rear and front seats must be removed
in order to watch the fuel level in the fuel
tank while adding fuel.
●Be careful not to spill fuel or overfill the
tank.
●Do not fill into the filler tube because gas-
oline could overflow.

NOTE:
●Wipe off any water on the spark plug or
inside the cap before installing the spark
plug cap. Push the spark plug cap down
until it clicks.
●If a torque wrench is not available when
you are fitting a new spark plug, a good
estimate of the correct torque is 1/4 turn
to 1/2 turn past finger tight. Have the
spark plug adjusted to the correct torque
with a torque wrench as soon as possible.
WARNING
Be careful not to damage the insulator
when removing or installing a spark plug.
A damaged insulator could allow sparks
to escape, which could lead to explosion
or fire.

Replacing the fuse
The fuse is in the electrical box 1.
To replace the fuse:
1. Remove the cap 2, pull out the red lead,
and bring the fuse holder 3 out of the
electrical box.
2. Open the fuse holder and replace the
fuse4 with one of the correct amper-
age.
WARNING
Do not use fuses of higher amperage that
those recommended. Substitution of a
fuse of improper rating can cause exten-
sive electrical system damage and possi-
ble fire.

Bleeding the oil injection
pump
If the oil tank becomes completely empty,
or any hose connected to the oil pump has
been disconnected, the oil pump must be
bled to ensure proper oil flow.
If bleeding of the oil pump is necessary,
have a Yamaha dealer bleed it.Fuse amperage: 10 A
