So there’s no info on doing coil on plug for the Zg1000. I searched but it must have been lost during the crash. A member used to offer them it doesn’t anymore so I don’t think I’ll be hurting his hustle. I had been wondering why my bike was running a little strange almost like 3 cylinders but it wasn’t. I pulled the plugs and had a look one plug looked a little different color then the other. I put new plugs. Pulled the boot for the funny looking plug and tested the resistance 20k ohms. I tested a spare I had 5k ohms. So I installed the new plugs( I didn’t have D8ea laying around but I had a set of DPR8ea-9 laying around from a bike that was totaled before I had a chance to install)and spark plug cap and the bike ran a lot better I checked prices for new plug boots and coils and it’s cheaper to get a set of coils and harness from a zx9/zx14 or several other models that are compatible. It can be wires in series or in parallel if you add a 1 ohm 20 watt resistor to the positive lead for each of the coils before you go add the extra wire from each of the red wire wire that run to each of the original coils. 4 red wires total branched off the red wires to each of the original coils. The advantage of running parallel is if one coil goes bad you won’t lose both cylinders. So I bought a set of zx9 coils with wiring harness for $60 off eBay, 2 1 ohm 20 watt resistors and two 4 pin male and female connectors. So I’m in under $100 for a coil on plug setup plus some time. These parts for the zg are getting old and I guess the zx9 coils aren’t exactly new but I think it’s a better option then buying new zg coils, wires, and plug caps. The left wire on the new coil runs to the red wire coming from the igniter on all new 4 coils then the black wire from the left coil would run to the right wire on the coils on cylinder 1-4 and the green wire would run to the right wire on the coils on cylinder 1-3. Obviously your going to have to add wires so you have two green and two black to run to each of the 4 new coils. You would run the resistor in-line of each of the red wire to the original coils and after that you will make the one red wire for each original coil 2 wires to run to the new harness so you have 4 red wires total. The original coils have a higher resistance and this will create the added resistance that will be lost by adding the new coil on plugs which have a lower resistance I googled how to do it hope I got it right. Running in series should be easy running in parallel may be a bit more difficult. If anyone has done this and needs to correct anything feel free to add any info to the post. This should be a sticky I would think. Your also going to want to take the cover from your original plug boots to add to the coils to keep water out. I attached a picture of compatible coils you can use to do the modification

. I had them from my cbr1000f that got wrecked.
