GENERAL INSTRUCTIONS
• Check the ignition system according to the sequence specified in the Troubleshooting. (!15-2)
• The ignition system adopts CDI unit and the ignition timing cannot be adjusted.
• If the timing is incorrect, inspect the CDI unit and A.C. generator 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

 17-3.

• Inspect the spark plug referring to Section 3.
• Remove the A.C. generator and pulser coil referring to Section 14.
