IGNITION SYSTEM INSPECTION AND SERVICING
The circuit working principle is shown in the picture below.
Note: The CDI ignition system has already been adjusted in the factory, so there is no need to readjust it. If
inspecting ignition function is necessary, take followed steps to inspect ignition timing.
• Remove the ignition timing hole cover (or remove the fan cover).
• Rotate the generator rotor, and align the “F” mark on the rotor with the crankcase timing ignition mark.
• Clip the ignition timing indicator light wire clip on the high-voltage end of the ignition coil.
• Start the engine and keep it in idling condition.
• Observe if the mark on the crankcase aligns with the “F” mark on the rotor.
• Slowly increase the engine rpm to 5000 r/min. At this time the mark on the crankcase aligns with the rotor
