Howdy!
Yes, several people have had the clutch basket issue. Mostly due to drag racing it though. The search for lighter and lighter weight sometimes leads to compromises in places. The rivets in the clutch basket can be replaced to keep them from breaking again.
But if you don't tear down the motor and thoroughly clean the shrapnel out of the motor from the grenaded clutch, then you're destined for a crank failure.
