10-22 ELECTRICAL SYSTEM
IGNITION SYSTEM
NOTE:
The fuel cut-off circuit is incorporated in this ECM in order to prevent over-running of engine. When engine
speed reaches 7 200 r/min, this circuit cuts off fuel at the fuel injector. But under no load, the clutch lever is
pulled or the gear position is neutral, this circuit cuts off fuel when engine speed reaches 7 100 r/min.
#
Under no load, the engine can run over 7 100 r/min though the fuel cut-off circuit is effective,
which may possibly cause engine damage. Do not run the engine without load over 7 100 r/min
at anytime.
