STARTER INTERLOCK
GENERAL
The starter interlock system is designed to prevent unin-
tended start-up and/or forward motion of the motorcycle with
the vehicle’s side stand not retracted.
tended start-up and/or forward motion of the motorcycle with
the vehicle’s side stand not retracted.
Two circuits make up the starter interlock system.
Starter Circuit
The starter circuit prevents the motorcycle from being started
unless a ground has been established at the starter relay.
This ground may come from one of two sources.
unless a ground has been established at the starter relay.
This ground may come from one of two sources.
a. By placing the motorcycle in neutral and grounding
through the neutral switch.
b. By disengaging the clutch and grounding through
the clutch lever switch.
Once the starter circuit is grounded and the starter button
pushed, the starter relay can be energized. The energized
relay then permits the starter motor to crank the engine.

Ignition Circuit
The ignition circuit prevents the motorcycle from operating
unless a ground is established at the ignition relay. If this
ground is not established, the ignition system will be not
turned on and the motorcycle will not run. Grounds may be
established three ways.
unless a ground is established at the ignition relay. If this

turned on and the motorcycle will not run. Grounds may be
established three ways.
a. By retracting the side stand and grounding through
the side stand switch.
b. By placing the motorcycle in neutral and grounding
through the neutral switch.
c. By disengaging the clutch and grounding through
the clutch lever switch.
Note that the ignition circuit allows operation in gear with the
side stand extended if the clutch is disengaged. However, if
the motorcycle is in gear with the side stand extended, and
the clutch is released, the ignition ground is lost and the igni-
tion system is turned off. This system will prevent operation of
the vehicle if forward motion is attempted with the side stand
down.
