Re: Auto shifting.
There is little doubt in my mind that the best use of these small engines is with shifting gears. I have done several DIY manual shift setups. This auto shift should be interesting. I do not have type of shifter you have, mine is one of those centrifgual shifters. However I think I can optomize the weights.
Not sure that I will get to jump right on this project, as I have so many motorized bicycle projects. However this thread has motovated me.
