Note: The fuel cut-off circuit is incorporated in this ECM in order to prevent over-running of engine. When engine speed reaches 9500 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 9000 r/min.
Caution: Under no load, the engine can run over 9000 r/min, even if the fuel cut-off circuit is effective, and it may cause engine damage. Do not run the engine without load over 9000 r/min at anytime.
