Man... what an awesome motor! I have replaced the ETEK motor with an ME0708 from John at Marselectricllc.com - THANKS FOR YOUR HELP!!!
So... I had a rather unfortunate problem with the Manta Etek whereby it started to lock up due to warping on a rainy ride home a week and a half ago. It was running more and more inefficiently and i measured continuity between the body of the motor and the positive and negative posts - the rotor - the very interesting guts of the motor - had dished to one side and was rubbing the one permanant magnet and the rain was the only reason that it spun at all near the end. I barely made it home and - if the driver of the v8 Mercedes that was behind me is reading this, please don't ever tailgate a motorcycle in the rain. Next time, I'll just stop in the middle of the road and go toe to toe with you. On a more positive note, I took it for a run with half charged batteries and it was quieter than before, and it was every bit as fast. After the run, i turned down the juice on the Alltrax 4844 to 85% for my commute tomorrow.
