I'm looking into buying the shift kit from SBP, and i have 7 gears on my rear wheel to work with. I'm trying to get passed 40 mph, so will this be possible without any other mods on my 66cc bike? Or do I need to get an expansion chamber muffler and higher performance air intake to reach these speeds? thanks
