I've decided to do the coil over plug modification on SERENITY, so first step was to purchase the coils.
After looking on eBay I found a set for 00-02 Kawasaki ZX6R ZX6 05-08 ZZR600 Engine Motor Ignition Coil Packs w/ Harness, for a total cost of $30.00. Must have the harness which is needed to adapt the Ninjette wiring to the coils. It's important to get the harness, because the coil connectors are different.
Next step was to unwrap the coil harness, so I could cut the OEM connectors from the harness.
Cut at the OEM splice points, which there are two.
OEM connectors ready for modification.
Wiring is easy just connect the red to the red wires, and the other wires to each other.
SIDENOTE: temporarily I've put male blade ends on the coil over connectors, so to just plug them into the existing wiring on the Ninjette. I did this while I'm testing these out, if something goes wrong I can easily plug the old ones up. Once I'm confident in them I will splice and solder them permanently, and removing the OEM coils
After that it's just as simple as installing the coil overs like you would the regular plug caps.
Removed the OEM coils
no real noticeable difference between the OEM Vs ZX coils. The advantages are eliminating the plug wires, and the spark plug caps, which need to cleaned, less to go wrong hopefully. After testing, I decided to remove the OEM coils, and brackets, which by the way they were spot welded on.
