In our bikes, current flows through the coils, which have two sets of windings, basically making them a transformer. The electric current sets up a magnetic field in the windings. When the points open to stop current flow, the magnetic field collapses. The collapsing magnetic field causes a back current in the windings, but since the points are open, the only place for it to go is out the secondary windings to the spark plugs, where it is forced to jump across a gap, which lights the fuel mixture. All of this is collectively called an "Inductive Discharge Ignition", which is pretty much based on points and coils.
In the 1980 models, Suzuki replaced the mechanical points with a box of transistors and called it an "ignitor". It was actually a poor choice of names, as it does not ignite anything, it only interrupts current flow, just like the points did. Regardless, since it was new and electronic, a lot of people call it "CDI", which is not correct.
Dyna makes a conversion kit for these bikes to replace the points with an electronic version, but it still uses the stock coils or an upgraded version of them. It is still not a Capacitive system, even though it is electronic.
Apparently Mailo has come across what might be a "CDI" system, but none of us has seen one before, so we are still guessing.
