what kind of 450cc injectors are they? meter the voltage at your fuel pump. how are you verifying your fuel pressure? what does the "chip" in your ecu do? what are your a/f ratios like? i am assuming rich as hell and you can't make a flame above 4500rpm. what does your timing look like? there are many questions you need to answer before ANYONE can help you. there are many things that can make a car not rev. does the engine rev witout a load?
