Did you find the source of the "screeching" noise?
Thanks for the schematic. You can see from this that you can evaluate the secondary by measuring resistance between ground and the plug wire terminal. Mine was 6K3.

I think it was the mechanics of the engine rubbing without the ignition of the spark. Works inside moving without combustion.
There's always been like a high pitch whine within the clutch crankcase especially at high speeds and low throttle. But other than that she still runs like a champ and pushing 3,000 miles soon on engine.
Still can't believe I had an extra CDI laying around that I hadn't used and thought I did LOL.
