Is that the same tool ya used to remove the paint saver ? I believe old Og invented that several years back, while he was sitting out front of his cave, trying to come up with a device to clobber those pesky dinosaurs over the head with.!!

Here are the pics to convert to a “Harley Style” rotor and stator. Note you must use both matching rotor and stator because BDM is a 24 coil and Harley 12 coil.

First note the diameter difference. (BDM is smaller)

The inner primary has some bosses added for no good reason. (Hmmm)
I used an air grinder to remove the material. I covered everything I could with foil so it would not get shavings all over chain etc.
Here is the result.
One final note. The BDM Rotor is thicker.
Now Harley
Fortunately the Rotor came with a spacer that would compensate for the difference. Just be mindful of that if you convert.

So here is the real kicker.
The reason I had the charging issue in the first place is the teeth were sheared off the rotor.
If you look closely you can see them missing in the pic.

Found the teeth.
I suspect the nut had come loose and it was moving relative to the crankshaft and sheered off the teeth.

yep probably right that nut backs off and there goes the rotor teeth.

Good question vs the 12
I cannot get the Photo Bucket pics to work, but here is Jake's step by step on how to install the 40 Amp compufire stator system. I ordered the same kit and replaced mine years ago and it was easy to do.
