The CDI does not work as it should. The box is missing a wire for sensing neutral properly. The ATV will not crank without the clutch pulled. The factory box would crank with the transmission in neutral or when the clutch is pulled. The key no longer shuts the engine off. The factory CDI would kill the engine with the key. The box is not physically the correct dimensions to attach th the frame using the factory mounting points. This is not a Direct Replacement for OE No 1YW-85540-20-00!
