    Ignition stamp for Dyna-S Replacement (ND vs KD)

    I'm trying to order a dyna-s to upgrade the ignition from points. Z1 has two different ones for the 78 GS750. One for bikes that had a nippon ignition and one for bikes that had a kokusan ignition. Supposedly it's stamped on the ignition with a kd or an nd, but I'm having trouble finding it. Can someone help me out here to locate the stamp, possibly with a pic of where I should be looking....

    huh,
    thats news to me.
    550-1150 is the interchange on the dyna S with a couple years not included.
    the only part you still use is the advance rotor.
    the dyna S replaces everything else.

    note:
    maybe thats the difference..the advance unit.
    the way the dyna trigger fits the advance unit itself.

      Maybe the bolt pattern is different.
      Look very closely at the ignition plate. There should be a stamp on there that says KD or ND.

              I think it has to do with the shape of the advancer... I believe Nessism has come up against this on the 550 & managed to fit an ND on a KD but with some need to clearance the inside of the cover or something.

              Lets have a pic of what you got! Sure we can work it out.

                that sounds logical.

                  That's what the dyna website is saying the difference is between their dyna s DS3-1 and the DS3-2.... how it works with the different advance units whether you had an nd or a kd ignition from the factory..... I looked under the the points cover but couldn't find the stamp for the life of me...

                    According to the exploded views at Alpha Sports, the condensors are lying flat at a Nippon Denso, and are pointing outwards at a Kokusan.
