This is a brand new aftermarket generator stator, supplied as a direct replacement for the original unit on the Kawasaki KX 250. Fitting is plug-and-play and needs no modification: the stator arrives with its connectors and rubber grommet already in place, so it goes straight back into the magneto cover on the original mounting points. The unit is supplied with a long 925 mm harness from the grommet to the plugs, so the loom can be routed and secured exactly as the original was.
It is built using the highest grade of lamination materials and the highest grade of copper winding, resistant to 200 degrees Celsius, so it holds up to the heat inside the ignition cover far better than a tired original. The package includes the pickup pulsar coil, the connectors, the rubber grommet and the back plate. All products shipped are tested before they leave the factory. Full dimensions, wire counts and winding resistances are listed in the table opposite so you can check the unit against your original before ordering.

Frequently Asked Questions
Does this stator need any modification to fit?
No. It is a plug-and-play direct fit for the original stator, supplied with the correct connectors and the rubber grommet already fitted, so there is no cutting, soldering or rewiring. Clean the sealing face of the magneto cover on reassembly and route the loom exactly as the original was routed so it cannot be caught by the flywheel.
What is included?
It is supplied with the pickup pulsar coil, the connectors, the rubber grommet and the back plate.
How can I tell my old stator has failed?
The usual signs are a weak, intermittent or completely absent spark, a machine that is hard to start when hot, a misfire that comes in as the engine warms through, or lighting output that has faded away. Measuring the windings against the resistance figures in the specification table will confirm it: an open circuit, a badly out-of-range reading, or continuity from any winding to earth all mean the stator has failed.
Which resistance readings should I expect from this unit?
Three circuits are specified. The alternator winding reads 2.4 ohms between yellow and yellow/white, the source winding reads 11.2 ohms between red and white, and the pickup coil reads 245 ohms between white/yellow and green/white. All three carry a tolerance of plus or minus 20 per cent, and none of them should show continuity to the stator body.
