SERVICE INFORMATION

GENERAL INSTRUCTIONS
• Inspect the ignition system according to the sequence specified in the Troubleshooting 15-3.
• The ignition system has a CPU in the CDI unit, so the ignition timing is not adjustable.
• Do not drop or impact the CDI unit with strong force to avoid damage. Be careful when
removing it.
• Loose connector and poor wire connection are the main causes of faulty ignition system. Check
each connector before operation.
• Check the spark plug heat range. Use of spark plug with improper heat range is the main cause of
poor engine performance or burned engine.
