Just in case anyone else was wondering if it was possible. Kind of a crude conversion, but it starts and runs ok. Low budget fix I guess, lots of die grinder work on the housing and cover piece to make it all work. The wiring patch work inside the headlight was the surprise behind door #1, the point setup was the surprise behind door #2. A friend of mine warned my that the cheap ones are always the most expensive..........
I know a guy who bought a custom chopper w S&S harley-type engine. I think from suckerpunchcycles or some place like that. He converted it to points or tried to anyway, because he got sick of the problems he kept having with the electronic ignition.
Looking ahead on the Frankenbike project, any ZN owners out there that have installed a Dyna system on their bike ? I'm pretty sure the points were mounted in the modified original housing, I have another uncut housing to use if I need it. An email to the Dyna tech line got a pretty vague reply. Hoping to use the system that's all inside and a lot less money......
If your ZN1100 had a mechanical advancer unit, then a KZ1000 Dyna S should work without much trouble.
If your ZN1100 had electronic-advance, then you will probably need to find an advancer unit from a Kz1000 and want to confirm the timing plate of the Kz1000 will fit into the ZN1100 housing. The electronic-advance timing plate will look very different, but the older style plate might still fit, and in that case a Dyna S plate should fit.
I'll post a drawing of the timing plate.
You want to make sure you have 3 ohm or higher coils. The stock coils would have been less than 3 ohms, and not compatible with the Dyna S, so you'd need non-stock coils.
This drawing will show you the Kz1000 timing plate and where the mounting bolts will be etc. so you can compare it with the housing on your ZN1100.
Note the Kz900/1000 timing plates have those cutouts along the edge. The smaller bikes have timing plates that are plain circles.
The email I got back from Dyna suggested the DDK2-1C. I found more info on the Z1 site that indicated a different housing from a J model would be needed for that kit to fit the ZN. I attached a picture of the points plate and the mechanical advance unit that was installed with the points. The original housing was rather crudely modified to fit the plate and is probably not usable. I have a spare ZN housing, but should I be looking for a pre electronic KZ 1000 housing and cover to use with the mechanical advance ? I might be able to use the less expensive DS2 system then.
If you scroll down the figment chart, you will see that the ZN uses the very same seal as all the J model engines , that is all KZ1000 and 1100 from 1981 onward. It also fits all the 1000 Concours and others.

Measured the seal again this morning. The ID listed is about right, 1.250" or about 32 mm. The OD is about 1.890" or 48 mm. The seal part number is listed for a lot of other models but maybe not for the r/h housing ?
