hey guys, ok so i have a 2004 honda 400ex. its all stock currently. i want to pipe & jet it. but dont wanna get taken for a ride at honda. can someone suggest what i should do to it, and how much it should run? honda is telling me like 1800 for nerf bars, a pipe, jetting it, front and rear skids. not sure exactly what else, but that seemed high to me. help a girl out!! school me in the things i need to know.
