Hello Jonathan and welcome to JustAnswer!

CDI stands for Capacitive Discharge Ignition and basically is the ignition box, e.g. provides voltage to the spark plugs at the appropriate timing.

Depending on your experience you may be able to repair a CDI box, I am not sure if you can rebuild it.

Hope this helps but if you have questions let me know.
