    Rev Limiter

    Bike: 1980 GS750L

    I'm confused. Is the "ignitor" really a CDI?

    I transferred the Dyna DL-300 rev limiter from my 1977 motor and it doesn't work. Either it is dead or this motor needs the CDI version.

    HEP!

    An ignitor is not a CDI.

      As mentioned, the ignitor is not a CDI.

      It is an unfortunate choice of terminolgy for the device, as it does not "ignite" anything, it is merely some transistors that replace the points.

      The "ignite" part of the system is still handled by the coils.

      In a CDI system, there is a capacitor that is charged up and discharged to provide the spark, hence the name of Capacitor Discharge Ignition.

        The Dyna website has trouble shooting tests for the ignition system

        It should install the same for both motors

          well, I called Dyna. Great people. Larry said since it was roughly a year old send it back and they'd test it. He said he'd even ship it back to me for free!

          BUT... I broke the &^%$#@ thing taking it off the bike

          So, new one is on it's way from Z1.

            Just in case someone else needs to know, you must cut the orange wire and then it works fine.
