CDI box

Recommended Posts

is there any difference between the "E" model and a "S" model? If so, can they be switched?

E CDI allows 500 more rpm. Not really noticeable. The rev limiter cuts in quite different though. Much "harder" on the E.

To use an E CDI in an S/SM you pull the green wire from the big plug (someone else pipe in if I'm wrong please). Not sure about going the other way.

On one the kill circuit is "connect to ground" the other isn't.

I've been running an E CDI for a couple years now. If it's cheap sure, not something to spend money on. Unless the extra 500 rpm will get you across a finish line quicker.

Pretty much covers it. To try an S box on an E, hold the KILL button down. To use and E box on an S you have to disconnect the green wire in the large connector.

I see you have 1 of each model.
