side of the machine. Press down on the brake
pedal to activate the rear brake.
EC158001
FUEL COCK
The fuel cock supplies fuel from the tank to
carburetor while filtering the fuel. The fuel cock
has the two positions:
OFF: With the lever in this position, fuel will
not flow. Always return the lever to this
position when the engine is not run-
ning.
ON: With the lever in this position, fuel flows
to the carburetor. Normal riding is done
with the lever in this position.

STARTER LEVER (CHOKE)
When cold, the engine requires a richer air-fuel
mixture for starting. A separate starter circuit,
which is controlled by the starter lever 1, sup-
plies this mixture. Push the starter lever out to
open the circuit for starting. When the engine
has warmed up pull it in to close the circuit.
EC15V010
TACHOMETER
A stepping motor type tachometer is provided
for greater accuracy of the tachometer 1. This
tachometer features the following:
Sweeping:
Moving the main switch to "RUN", the
tachometer hand sweeps widely once over the
tachometer face and then returns to the zero
position, as initial operation. This is called
"sweeping". When the engine is started during
sweeping, the tachometer indicates the correct
revolutions after sweeping is over.
Out-of-step indication:
If this tachometer is subjected to impact, etc, it
may allow its hand to point to the position b
stepping out of the position a where the hand
should be for correct indication. This is called
an "out-of-step" indication. A similar phenome-
non may take place when the main switch is
moved to "OFF" during sweeping or at high
rpm (as in a plug chop) or while the machine is
transported, though it never happens in normal
riding.
