hey everyone im ben and i just acquired a minibike off my mate and the engine in it now is a 160cc Victa high compression type from a mower and it has no power, is there anyway to mod it so it gets enough power to propel the bike to at least 40km/h, cheap mods, ive already removed the decompressor and plugged the opening on the head, its running a slide type metal carby. plus im very limited on tools, so i need easy mods too
