SERVICE INFORMATION
GENERAL INSTRUCTIONS
• Check the ignition system according to the sequence specified in the Troubleshooting.
• The ignition system adopts CDI unit , change gear control and the ignition timing cannot be
adjusted.
• If the timing is incorrect, inspect the CDI unit, A.C. generator, change gear control and replace
any faulty parts. Inspect the CDI unit with a CDI tester
• Loose connector and poor wire connection are the main causes of faulty ignition system. Check
each connector before operation.
• Use of spark plug with improper heat range is the main cause of poor engine performance.
• The inspections in this section are focused on maximum voltage. The inspection of ignition coil
resistance is also described in this section.
• Inspect the ignition switch according to the continuity table specified in page 17-5.
• Inspect the spark plug referring to Section 3.
