Just wanted to give this it's own thread. Here's the info on the new brush holder for Motenergy motors: http://evmc2.wordpress.com/2012/11/10/motenergy-new-brush-holder/

It's $99, and you can get it from any dealer or direct from Motenergy. All the new applicable motors shipping currently have the new design.

John is sending me a sample to do a write-up and testing on, so stay tuned.

Thank You - i will definitely buy into the new brush holder...

i like the less heat to the motor and increase of power limitation...

Thank You Ted

OK, got the post up. It's a pretty tidy bit of design:

I'll fill in this post with some of the details later on...

Here is the backside of the holder assembly showing the welded bus:

Total elapsed time for the swap, about 10 minutes with the motor in the bike.
