Alternatively, why don't you circulate oil in the whole motor, and use the copper pipe as radiator in front of your bike?
Anyway, I love what you do, so keep it up!

The air gaps in the windings and the winding paper is the major barrier. I found with mine that there was a large delta T (up to 40degC) which was improved substantially by adding about 60g of themal epoxy to the sides of the windings.
