Ok. I,ve been away for a while but I'll bite since no one else has.

Most poeple have problems with the woodruff key shearing when the bike backfires.

In your case it would seem to me that the starter is remaining engaged ,or becoming engaged, while the bike is running, and the starter clutch is not working as intended.

Bolted to the back of your rotor is a clutch , which is designed to lock or engage in one direction, to turn the engine over, once the engine spinns faster than the starter motor it disengages.

If this sprag clutch was to remain engaged the starter assembly and gears would spinn much faster than designed to and would most likely be the culprit of your broken cases. :D
