Has any one with a wr450 experienced a catastrophic stator/flywheel failure? I have recently worked on two wr450's (different owners) that have had the same problem. In both cases it appeared that the two 4mm stator screws backed out and allowed the stator to tangle with the flywheel. In both cases the stator and flywheel were destroyed. What's puzzling is how in both cases it also managed to sheer off all six of the bolts that hold the starter sprag to the flywheel. These bolts are recessed into the flywheel and none of them showed any signs of backing out or being loose prior to the carnage. I have inspected two other '03 wr450 (mine included) and haven't found anything to to be out of order, so I reassembled with plenty of loctite.
