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 ?!?!
No the total bill was $12xx. $200 to remove from doner Bike and $200 labor to install. The parts were $845.
