 SERVICE INFORMATION
 GENERAL INSTRUCTIONS
 · Inspect the ignition system according to the sequence specified in the Troubleshooting 15-2.
 · The ignition system has an electrical auto aligner 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 of 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.
 · Perform inspections according to the servicing procedures specified in each section.
