SERVICE INFORMATION
GENERAL
The CDI may be damaged if dropped. Also if the connector is disconnected when current is flowing, the excessive voltage may
•
damage the module. Always turn "OFF" the ignition switch before servicing.
•
Use spark plug of the correct heat range. Using a spark plug with an incorrect heat range can damage the engine.
•
When servicing the ignition system, always follow the steps in the troubleshooting sequence on (page 16-2).
•
The ignition timing cannot be adjusted since the CDI is factory preset.
•
A faulty ignition system is often related to poor connections. Check those connections before proceeding.
