yeah man, i don't know if you'll find your answers here but it's certainly worth the read and i'd bet everything i have that someone posting in this thread knows the answer and would willing share it with you.
ok so I want to build a bike like the one in the pic. to do it I need to stretch a bike frame a foot and drop it to 6 inches higher than the tire. I have a 4 cycle hausheng engine that runs great and has not been broken in. problem is I don't know how to weld yet. I want to use a 7 speed hub so I can keep the engine at a lower speed. I also think I have to stick pedals on it some where to make it street legal in MA. I know basic machining but haven't gotten my lathe running yet. I will be making parts for the engine and a custom muffler.
