Kugoo M4 Pro Stem Tightening, Cooling, Wiring Guide And Ride

In this video I go over how to tighten the stem on the Kugoo M4 Pro Electric Scooter and stop the dreaded wobble. I also lightly go over the wiring and have provided a wiring guide below👇 I found it too difficult to show the wiring in place so the guide tells you what wires go where.

While the scooter was apart I took the opportunity to apply thermal conducting tape to mate the controller flush to the deck. This should help displace heat from the controller into the scooter deck keeping the controller cooler, a worthwhile mod for any scooter and could stop premature failure due to heat.

I then take the scooter for a ride testing the fixes and try out the regenerative braking feature of the controller.
