Where is the cdi box located on a 300ex?

The CDI (Capacitor Discharge Ignition) box on a Honda TRX 300EX is typically located under the seat, near the battery. To access it, you’ll need to remove the seat and possibly the side panels. The CDI is a rectangular box connected to the wiring harness, often mounted to the frame. Make sure to disconnect the battery before handling any electrical components.
