Not sure if you realize the drums are manual adjust, not automatic like cars that had them. It is common that by the time they do get manually adjusted, the shoes are pointed in the middle. I adjust them until they drag. They may need readjusting each ride until the shoes wear in enough to go longer.
When I first got an FL350R, I adjusted the brake cables like I would on a bike with cable brakes. I left play. I figured out that there is no need. In fact, I adjust the cable so that the plungers in the master cylinder are partially pressed in. Adjust too far and the plungers will pass the holes where the fluid fills them from the reservoir and they won't pump up. Just a little less pre-load than that will get you the most fluid movement.
