By really winding it up, you can touch 50mph, but it won't last long.  You'll either scorch the piston or explode the variator. Either way, it's done for. With a 72cc BBK, and an unrestricted CDI, you can maybe do a reliable 35mph.  The extra speed you achieve only comes from higher RPMs. And it will surely blow up on you if you push it much past reasonable RPMs.
