Paul: is the flywheel on your wife's bike just a "cup" design, or does it have some ventilation or oil cooling features?
Some bikes have a oil passage in the end of the crank that meters a bit of oil into the stator area for cooling....
I don't think any of the BMWs do that............
Hers is a 2007 model - the rotor/flywheel is solid.
Thanks Paul!
Very similar if not identical in design then ...
Not sure if the failure rates are higher on the GS models or if we are just bigger whinners ...
Maybe a little of each, but there are many GS bikes out there running around for every one F800S out there, so we would expect to see a lot more failures of any component on GS bikes compared to S or ST bikes.
Thanks Paul!

Yes I am a whinner as mine failed at 52,000 miles on the road. It was giving me clues for some time, but I did not understand. A no start a few times, thinking bad battery. Changed battery and hit the road and it got worse and woud not keep the engine running at idle. Replaced in Oklahoma City at about $1200 plus. Two hours to remove from doner bike and two hours to install plus price of a new one, and I didn't get the new flywheel. I now have 73,000 miles and all is fine so far. I check the temp of the side cover with a inferred temp checker and it is always about 30 to 40 degrees hotter the the engine block. Engine about 190 and cover about 230
Do the aftermarket ones still put out the 400 watts?
I believe one solution that was being touted was reducing the output to reduce heat but I don't know if anyone went with that idea. IIRC as stated above Electrosport is trying to compensate for the heat by using better wire/insulation and they say it should be good for higher temps than the stocker would get.
Roy are you saying they charged you 1200 dollars just for a stator ?!?!
You said you didn't get the upgraded rotor though. Sounded like they just swapped the stator from the "donor" bike over to your bike and left the rotor in place.
