Actually I am fairly convinced they have it solved. And it tends to make sense. As lots of us that got motor/controller recalibrations it would fix it for a few hundred miles then it would return.
The reason for this is it would recalibrate to the current positioning of the motor encoder in the back of the motor which is seated with an epoxy like potting material. Over lots of high heat thermal expansions, this material would soften just enough that the encoder would shift position slightly.
One reason it tended to be fine for the first 2000 miles or so, and for those who had less than that, it occurred during summer. In fact most of us had the majority of the issues during the hottest months when the motor was unable to dissipate heat as well due to a higher ambient temperature.
I believe the engineers are reporting their findings to Mr. Walker tomorrow and we should hear by mid week the official fix for the glitch. It may be a simple trip to your dealer for a 30 minute motor swap, or if you live far from a dealer, a motor shipped in a box with R&R step by step instructions and a diagnostic kit loan to calibrate the new motor to the controller if you feel comfortable doing that sort of thing yourself. Like I said in an earlier post, it's 1000 times easier than swapping the motor in a gasoline bike if you have ever done that. If the key is off the contactor is open and no voltage is going to the controller and definitely not to the motor so there's no risk of anything if the wires touch anything, and you really can't screw it up as the 3 wires are clearly marked with permanent marker dots, 1 dot, 2 dots and 3 dots for easy reinstallation.
If you're not comfortable doing that, I'm not sure what they will do, as it would be definitely be cheaper to send a mobile technician city to city to do quick motor swaps for customers than ship crates out to people then ship bikes to California and then back again.
Good news is I feel comfortable the fix is on the way.
