Also a 72 tooth sprocket (11.750"od) would bring the crank rpm closer to normal crank speed for the average person, 80rpm~ (5:to1~).
I just watched the video - that choking noise you hear from the motor is because you are overgearing/overloading it. You need to let the motor spin faster in a lighter gear or use less throttle. I wouldn't be surprised if you wear out the motor with it choking like that.
What I also miss is that whole shifting and throttling action, getting the rpm changes sounds cool, even with a whiny motor.
