I recently purchase the 75.00 cdi by le parti I spent three days trying to start it with no luck installation instructions where very simple I grounded the stator black wire to the enging,the black wire from the cdi box to the frame as well as a black wire for the coil and attached the orange wire to the coil as well. The red wire from the stator to the red wire on the cdi box and the green wire from stator to the cdi box and the black and white wire from cdi box to the kill switch yellow wire for the lights anyway no matter what I did it would not start I then decided to remove it and throw it in garbage piece of crap. Well I installed my original stator back on and my engine fire right up on a freshly rebuilt engine maybe I got a defective item I dont know if theres any returns on electrical part maybe I should look for a more expensive part.
