G'Day customx22, I have a 2007 ZX50, great little scoot, I bought a kit off ebay from a seller in taiwon, but it is not looking too good, it seems the ports are not as they should be, but that's life, try too save a few bucks and it costs more in the end. What I want is good pickup with ability to cruise at 80kph with ease, wit my current setup it goes off the speedo which is 80 so mainly I want more pickup. These are a great toy to play with, though it is not as good as it should be it is still enjoyable working on it. The speeds you are talking about sound a bit scary on one of these scooters, but it woud be fun to try.
