MULTI-FUNCTION DISPLAY
COLD STARTER KNOB
When cold, the engine requires a
richer air-fuel mixture for starting. A
separate starter circuit, which is con-
trolled by the cold starter knob "1",
supplies this mixture. Pull the cold
starter knob out to open the circuit for
starting. When the engine has
warmed up, push it in to close the cir-
cuit.
HOT STARTER LEVER
The hot starter lever "1" is used when
starting a warm engine. Use the hot
starter lever when starting the engine
again immediately after it was
stopped (the engine is still warm).
Pulling the hot starter lever injects
secondary air to thin the air-fuel mix-
ture temporarily, allowing the engine
to be started more easily.
SIDESTAND
This sidestand "1" is used to support
only the machine when standing or
transporting it.
• Never apply additional force to
the sidestand.
• Hold up the sidestand before
starting out.
MULTI-FUNCTION DISPLAY

distance that has been traveled
since it was last set to zero)
RACE MODE:
• Timer (which shows the time that
has been accumulated since the
start of timer measurement)
• Tripmeter (which shows the accu-
mulated travel distance in timer
measurement)
• Change tripmeter digits (capable of
change to any given ones)
