After 1984 there was an added throttle position sensor that tied into the CDI kill-switch wiring.  This was a safety function to eliminate engine start if throttle wasn’t fully closed.  This CDI required a round plastic 2-pin connector (see below).   We can provide the plastic plug if your model requires it, but we need to know this prior to ordering.

Contact us before ordering if your model has this WHITE plastic plug.

* Always check your timing when changing CDI’s to confirm it is set to factory specifications.
