A little off subject, but there's right at a half lb. of copper in that rotor. Considerin' it's a race bike, removing that 1/2 lb of rotating mass might help a tad.
....and also the first rephase.Congrats Signal! Far as I know, you're the first non-TCI conversion to run. View attachment 181941
Nice to see the scope traces of the stock magnet and coil and the greater voltage output of the rx coil.
Having excess voltage is easier to fix.
Thought 1
A single 4 or 5 mm hex head screw instead of a magnet.
2) smaller magnet and/or greater air gap.

Really like your "Dynamo Dynamometer" . Has a hum to it.
Try putting a pot into one of the leads of the rx pickup. Start at 0 resistance and then rotate tn some resistance and watch what happens.
Yup.If I put a 1981 rotor on a 1978 engine, does the woodruff key have the magnet in the right spot for correct timing?
So, with a 81 rotor and stator, I guess I have a good start for my '78.Yup.
