Hi guys I was just wondering if anyone knows if the huasheng 49cc 4 stroke gearboxes will bolt onto the 2 stroke pocket bike engines. I know they're a bit under powered but they're pretty cheap and you can get an upgraded version of them and they have a centrifugal clutch too. I've seen 2 or 3 bikes on YouTube they use a pretty small chain with the stock gearbox though.
