Hi,
I am looking for advice or info about cooling the motor on my sons 50cc KTM motocross bike which I have converted to electric.
The bike has run great for about a year. Yesterday in the 95 degree Mississippi heat we let a larger faster kid ride the bike and he made about 5 fast laps before the motor gave out. the motor still turned over, but it runs very rough and only at partial throttle. It looked like resin or something was seeping out of the motor too.
I opened the motor up and it smells like electrical death. There are also some chips out of the magnets.
What I would like to do is plumb an air inlet and outlet in the Oset 48v brushed motor ( new motor, not the one we burned up) and force air through the motor and through the bikes original aluminum radiators.
Can anyone tell me if a radiator originally used to water cool a gas engine will pull heat out of air circulated through a motor?
Will the circulated air even cool the motor?
Thanks!
this is a video of the bike in the shop.

This is a video of me riding it for a very short time. It is usually ridden by a 6yo.
