Thanks for the compliments guys!
I'm confused by this last modification. What changes did you make to your GXH50?
I better clarified my last post so that it made more sense.
The biggest modification was simply removing the pull start mechanism. I also did some trimming of the flywheel. I will also be trimming the output shaft after I am 200% convinced that my transmission is "bought off".
The bike is designed to be a pedal assisted motor scooter as opposed to motor assisted bicycle.
