One might think that removing the brake shoes would do the trick. I originally thought that too. No shoes, no brakes, right? Well, it doesn't work. As you back pedal and drive the clutch toward the NDS, the internal spring assembly compress TOO much, binds, and prevents the whole clutch assembly from reverse spinning. That prevents backpedaling. I have read about people adding washers under the spring, down inside the clutch body to prevent the binding. It seems to be critical to get the exact right thickness of washer to make it all work. I've never tried it myself.
