I have new motor with all new electrical and electrical is connected properly with no shorts(triple checked). It has a TBM light weight flywheel from Thrust Innovations and MSD enhancer & OEM stator.
Problem: ski runs awesome for about 20-30 minutes then smokes the stator and takes the CDI with it. This has happened 3 times now. The only thing that hasn’t been swapped is the flywheel. Any help or suggestions would be greatly appreciated.

so you tried swapping out the regulator?

^ this and check your ground cable ends for corrosion inside the crimps. A multimeter will generally ring out and show no issue on a borderline failing ground cable and its fairly common on the older cables.
Slow cranking and hot/warm cables are a good indicator too.
