1. In tough terrain the motor overheated quite often. I´ve machined a new motor housing out of a solid aluminium block and integrated cooling fins.
2. The freewheels are not sealed so dirt can easily get inside. By making a protective housing for the freewheel that now features shim rings no water or dust can now damage the inside.
3. The original motor mount was replaced by a new one made out of aircraft aluminium. The clamps that hold it to the frame are also made out of one solid piece.
Would love to learn more about your Cyclone motor improvements as I have a similar problem with it.
At least a few photos of the improved motor housing and freewheel will be very much appreciated.
