It's simply the laminated iron circular object directly under the flywheel. I guess it's called the stator, but I thought the stator was the whole assembly, including the plate. It is wound on three of the six poles for lighting, and two for spark power to the CDI, just as the stock unit and it screws into the stock stator plate using stock trigger coil.
here's the unit

It ohms out exactly the same for the ignition side, and makes a good blue spark when kicked fast enough.
At the suggestion of Gofasters, I measured the diameter and found it to be about five thousands smaller.
I wasn't talking about adding weight to the flywheel, I was talking about the actual bigger 14oz flywheel the DE comes with. I've been told the MC250 has about 35w for lighting with the 10oz, and the DE has about 40w with the 14oz flywheel and same 2k-2 stator.
I called tech support for this unit today and was basically given a brush off. The phone answerer went away and came back and said I either had bad connections or my trigger coil clearence was off, even though it can't be changed. I've been an electronic tech for 20 years and rebuilding bikes for 30, and all my connections were soldered. It's typical for these support guys to blame the customer.
I then changed back to the original unit, and it was back to it's old self, starting with half a kick. Problem with unit, but I know the manufacturer probably won't make good. It fits other bikes too. Late nineties RM250's and 125's, 97-02 KTM 300's, and several other's. Maybe ebay is my best bet since the coil is good, it just won't work on my bike.
Oh, and I know about the drain in the crankcase. I've already used it once. Saved a bunch of time and fouled plugs. I ran my CR into a creek last May. Had to take out the reed block and turn the bike upside down. Fantasic feature as long as you don't lose the bolt on the trail. I'm carrying an extra.
