POLL: stator / alternator failure on F800GS/F650GS twins please vote!

It seems there have been many stator failures in the F800GS & F650GS twins due to overheating.
The stator runs in a very confined space with no provisions for air or oil cooling.
BMW has recently released a redesigned flywheel which will likely remedy the problem.
You can read all about it here:
Post #399 has pictures of the new and old parts ...
Unfortunately, for those of us that are out of warranty, the new "generator set" is ~$900 USD.

The purpose of this POLL thread is two-fold:

1) Capture failure data vs. mileage (please vote even if you have NOT had a failure)
So as to determine the extent of this problem, and at what mileage failure is likely...

2) To PLEAD WITH ALL USA OWNERS that have experienced a failure to file a complaint with the US Government, regarding the issue esp. if you experiences surging or stalling (I would expect stalling) during the failure incident. (See post #420 of the above thread for details). This may help get resolution for the issue.
File a complaint(s) here:
