Stator/ rotor/ tuxedo mod problem

About a year ago my stator burned up so i replaced it and did the tuxedo mod, below is a picture of when i did it last july.
After i replaced it i rode it a total of about 4k miles from july to October and then this may till july. I started having performance issues on my way back home on a 2 hour road trip. When i stopped to get gas and it didnt want to start back up. Instantly i thought it was the stator but i just replaced it, so i tested it and the stator was grounding to the frame. After pulling off the cover and tux mod i found this.
Some nasty grooves, metal flakes in the drain plug filter and my stator was chewed up. What might have caused this? It ran fine for awhile and then something happened. Any ideas? Something shifting? Also do yall think ill have to change out the rotor?... i have a stator replacement already but i obviously dont wanna throw it in there if something is shifted. One of my pickup pulser coils wire got ripped out somehow

Did you feel vibration get worse over time? Wondering if balance dampers failed and allowed an abnormal amount of movement of the rotor, allowing it contact the stator.

Could also be an incorrectly made/aligned stator mod plate.

Nothin outta the ordinary. I mean riding in michigan is like riding through a mine field cause the roads are terrible. But nope, didnt feel any weird vibrations. All the bolts were tight as could be so nothing was lose. It worked fine for 4k miles, im dumbfounded atm. Do you think ill need a new roter?

Have seen a couple of wobbly rotors on here. Spin the crank and watch the rotor.

Other than that, the stator shifting on the tux plate. Did you unbolt the stator and plate and check those bolts?

Is that all metal on the screen or is there rubber mixed in?

Ill check for wobble. It was metal and gasket marker. Its flakes from when i cut it for the mod.. i think.

Did you remove the motor and pull the side case when you did the stator mod?

I remember last year there was a thread on here about whether or not it was a good idea to do a tuxedo mod without dropping the engine to pull the sidecase.with all the shavings that are created...can't be good for the inside of a motor with all those tight clearances...

Those are nasty grooves. Are the metal filings steel (use a magnet)? The inside of the rotor seems to appear to be worn more on one side, as opposed to evenly around the whole thing. Is that true? If so I would suspect the tuxedo plate is not drilled properly or perhaps the bearing behind the rotor is failing. Since aluminum is softer than steel I would not expect shavings to have caused that kind of damage. But I would not do the mod without removing the case either. Ther are only so many places steel can come from in these engines.
