Exactly what Slob said.
With cast you can never be exactly sure how things will go until you light up on it but Ducati crank cases have been good to me so far.
Burr out the muck, old threads and loctite back to clean metal.
Start building it back with weld metal.
Keep welding beads until the part is rebuilt.
Flat the surface the the original height.
Drill, tap and Timesert for strength.
Solid side stand again.
