WR rotor (flywheel) allowable damage?

How much damage on the inside surface of a rotor is too much? I realize the magnet generates current from rotating around the stator. So how much imprefection would allow a WR still to operate?
I had two bolts that tie the starter clutch to the rotor back out then shear off and grind around inside the rotor a bit. Stator is toast. Damage to rotor is primarily in the inner 10% of the race near the radius to the bolt face.
Dealer wants $100 for the rotor and I am inclined to throw this one back on with a new stator...just don't want to have to tear into the motor again. Curious if anyone else has experience with damage to rotors and success without replacing.
As a side note, mine had the dealer retorque fix, which kept the woodruff key from failing. Not quite sure why the starter clutch bolts backed out (2 sheared off, other 4 all hand tight).

What happens to the bolts is not that they simply shear rather they get loose, the heads hit the stator which in turn, shears the heads off.
