It only takes a single flake of steel, bridging between the trigger coil's steel core and the flywheel, to short out the magnetic field between the flywheel and the trigger coil's pole, and the cdi won't fire. A build up of iron dust on the trigger pole can do the same thing. You need to get an analogue volt gauge and check there is a pulse of voltage getting to the cdi. A digital gauge won't always detect the brief pulse but the needle on the analogue gauge will flicker so you see it. Some kawasaki use a 12v system of ignition so if the trigger pulse is getting through and it still isn't sparking then we need to get a manual and check the resistances and output voltages of the stator. If there is no pulse from the trigger coil then you check there is continuity from the cdi unit to the trigger coil and if that's ok you need to take the side cover off and get every flake of steel off the flywheel and stator pole. Steel flakes or dust can also short out the charging cores of the stator. The best way I've found for getting dust or flakes off is to use a rag and grab it and wipe it off. It takes a while fighting the magnetism but eventually it's possible to get every little flake out and enough dust off to prevent it bridging the gap between pole and flywheel.
