Gasohol
There are two types of gasohol: gasohol
containing ethanol and that containing meth-
anol.
Gasohol containing ethanol can be used
if ethanol content does not exceed 10% and
the fuel meets minimum octane ratings.
Gasohol containing methanol is not rec-
ommended by Yamaha because it can
cause fuel system damage or engine perfor-
mance problems.

2-stroke engine oil
If YAMALUBE 2-W is not available,
another 2-stroke engine oil with an NMMA-
certified TC-W3 rating may be used.Recommended gasoline:
Regular unleaded gasoline with
a minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)

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 attached to the electrical box.
To replace the fuse:
1. Remove the cap 1, and then pull out the
defective fuse 3 by using the fuse
puller2.
2. Install the spare fuse 4 of the correct
amperage.
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, 20 A
