I do the same as MTBikerTim. But I would highly suggest grinding a flat spot on the shaft. I didn't on my Feigao motor, and on the second run, the grub screw just couldn't hold tight enough after accelerating hard, and it grinded a cut all the way around the shaft. From then on, I would always make a flat spot and it hasn't caused a problem for me yet.
