Well something I didn't take into account was the weight of the engine....I just weighed the Lifan 79cc engine and it weighs 20.8 lbs without any oil in it.
The Honda GX100 weighs 23.4 lbs.
I am not so sure I am going to be replacing the Lifan any time soon.
Next step is to look into the Yamaha KT100 and see whether I can get enough gear reduction between the engine and the rear wheel to make it feasible. The KT100 is supposed to weigh 21 lbs and then I need to add a clutch.
