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 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).

Sidestand
The sidestand is located on the left
side of the frame. Raise the side-
stand or lower it with your foot while
holding the motorcycle upright.
NOTE:
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situ-
ations. (See further down for an
explanation of the ignition circuit cut-
off system.)
EW000044
w
The motorcycle must not be ridden
with the sidestand down, or if the
sidestand cannot be properly
moved up (or does not stay up),
otherwise the sidestand could con-
tact the ground and distract the
operator, resulting in a possible
loss of control. Yamaha’s ignition
circuit cut-off system has been
designed to assist the operator in
fulfilling the responsibility of rais-
ing the sidestand before starting
off. Therefore, check this system
regularly as described below and
have a Yamaha dealer repair it if it
does not function properly.
EAU00331
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch,
clutch switch and neutral switch) has
the following functions.
8It prevents starting when the
transmission is in gear and the
sidestand is up, but the clutch
lever is not pulled.
8It prevents starting when the
transmission is in gear and the
clutch lever is pulled, but the
sidestand is still down.
8It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.
EW000045

If a malfunction is noted, have a
Yamaha dealer check the system
before riding.
