i have a puch cdi stator plate. and mentioned it to vic from m23 and he told me that this cdi box would work with it. i guess it is the same ducati part number as the original. i was going to give it a shot. but i had one question, is the fly wheel specific to the puch cdis? i noticed on the one that harold had gotten from stevesmopeds that it seemed to have a nut on the inside. anyone know what up?
