How is it 'breaking'? Stock wheel will be good to mid 6000's. I've regularly spun mine to the 6800's with never a complaint, although it is on a jet drive. If you're going to see North of 7000 I might consider an aluminum one. If I remember correctly, you can go with a 2.4 16 amp with it's corresponding stator, shorter screws and a little wiring to save some weight. My first thought was is the pinion vibrating up into partial engagement and wreaking havoc on the ring gear or are you exploding the flywheel with high rpms.

It keeps knocking the teeth out of the center. Have been looking for an aluminum one for a while.

If we are talking about the 'teeth' on the outer circumference of the flywheel, look at possible starter operation when it shouldn't be, also sticking, and such. If it is the magnets coming loose underneath the flywheel, dont strike flywheel when removing it and check clearance on stator and top bearing.

Oh. Not sure what to make of that. If the splines on the end of the crankshaft are damaged in some way, I'm guessing that you are not going to have a good day.

Have you used a dial indicator on the splined shaft? Just a outside chance that it may not be straight (bent or out of round). If it is out there is the possibility it's creating a vibration causing a self destruct scenario.
You have nothing to lose by checking.
