Just bought a 2002 400ex....mint shape...K&N filter and jet kit. One thing i want to put on it before i right it hard is a skid plate but they cost so damn much. Just curious to know whether someone had made a home made one and if they could give me some sort of blueprints or measurements in helping me make one...got some aluminum at home i might use.. or some checkerplate...any suggestions would be helpfull
