Hmmm..you sure the replacements were DC based?
Personally, I don't put all my money in CDI's. They are most beneficial with mods that require it.

the dc units look just like ac unit, on your cdi there is a 2 wire plug, if there are two wires going into that plug you have a ac fired system. also check to see if there is a signal ( very low voltage ) coming from the pick up coil wire, most are blue with a white stripe

the stock stator wil be fine. coming from the stator side of the case are some wires, look and see if one is blue with a white stripe, that one goes to the cdi. check to see if their is a low voltage signal coming from it
