Later model Japanese bikes no longer have coils in the traditional sense. If you lift the hood of a later model car, you wont see a distributor, you will see individual coil packs sitting on top of the plugs. later model Japanese bikes have something very similar.
The COPS kit....or Coil Over Plug kit, basically does away with your stock coils, and then you have coil over plugs to replace them. There is NO performance benefit, but you do seem to get better reliability out of the COPS kits. I have one on mine. Sean sells ready made kits that were made by another forum member....Gannon.
