Speedometer unit The speedometer unit is equipped
with a speedometer, an odometer
and a tripmeter. The speedometer
shows riding speed. The odometer
shows the total distance traveled.
The tripmeter shows the distance
traveled since it was last set to zero
with the reset knob. The tripmeter
can be used to estimate the distance
that can be traveled with a full tank of
fuel. This information will enable you
to plan future fuel stops.

Fuel
Fuel
Make sure that there is sufficient fuel
in the tank. Fill the fuel tank to the
bottom of the filler tube as shown.
EW000130
w8Do not overfill the fuel tank,
otherwise it may overflow
when the fuel warms up and
expands.
8Avoid spilling fuel on the hot
engine.
EAU00185
cCImmediately wipe off spilled fuel
with a clean, dry, soft cloth, since
fuel may deteriorate painted sur-
faces or plastic parts.
EAU04284
ECA00104
cCUse only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and pis-
ton rings, as well as to the exhaust
system.
Your Yamaha engine has been
designed to use regular unleaded
gasoline with a research octane num-
ber of 91 or higher. If knocking (or
pinging) occurs, use a gasoline of a
different brand or premium unleaded
fuel. Use of unleaded fuel will extend
spark plug life and reduce mainte-
nance costs.

Fuel cock
Fuel cock
This motorcycle is equipped with a
negative pressure fuel cock. The fuel
cock supplies fuel from the tank to
the carburetors while also filtering it.
The fuel cock lever positions are
explained as follows and shown in
the illustrations.
ON
With the fuel cock lever in this posi-
tion, fuel flows to the carburetor when
the engine is running. Turn the fuel
cock lever to this position when start-
ing the engine and riding.RES
This indicates reserve. With the fuel
cock lever in this position, the fuel
reserve is made available. Quickly
turn the fuel cock lever to this posi-
tion if you run out of fuel while riding,
otherwise the engine may stall and
will have to be primed (see “PRI”).
After turning the fuel cock lever to
“RES”, refuel as soon as possible
and be sure to turn the fuel cock
lever back to “ON”!PRI
This indicates prime. With the fuel
cock lever in this position, the engine
can be “primed”. Turn the fuel cock
lever to this position when the engine
has been allowed to run out of fuel.
This sends fuel directly to the carbu-
retor, which will make starting easier.
After the engine has started, be sure
to turn the lever to “ON” (or “RES” if
you have not refueled yet).INSTRUMENT AND CONTROL FUNCTIONS
