    None of the GS's came with CDI. The resistance in coils for a CDI system is too low and if used with our electronic ignitions will almost certainly fry the ignitor. I don't know what the resistance should be for points systems but for electonic ignition (those systems with pickups and ignitors) you should use the 3 ohm (green) coils.

      thanks
      i think you just saved me from a few headaches

        Coil requirements, CDI used mostly in 2 cycle engines
        CDI ign .9 ohms
        elect GS ign 3 ohms
        points ign 5 ohms

            I have a 1981 GS 750 ex I replaced my coils with Dyna 3 ohms the green ones. A simple change and they work great. Andy

              hey snow rider: if you're not firing on just one cylinder, it's not the coils fault...

              4 cylinders, 2 coils. you do the math... while one cylinder fires on the compression stroke, the other fires on the exhaust stroke, so if your coil were bad, you'd be runnign on 2 cylinders, not 3.

              look for a fowled plug or a bad wire and save your money.

                Swap # 1&4 plug wire See what happens, if the problem follows the
                plug wire

                  it does seem to be a weak wire.
                  how can i change just the plug wire?
                  the wires are fused into the coil.

                    the wires are fused into the coil???
                    what kind of kangaroo setup is that???

                    i refuse to believe it...
                    lemme go check my bike and get back to you...

                      Heh, can't wait to see his response

                      I think there has been some discussion about replacing wires with the coils as they are, do a search in the tech section.

                        DYNA coils all the way mang!!
                        ...the 3 Ohm green ones with 2-posts...

                        :P

                          The wires are held in stock coils by something akin to hot glue. They can be gotten out with a little work and replaced.
