A kid said his 400ex with a 407 kit, hotcams camshaft, and white bros filter could beat my 300ex with k and n air filter, outerwears pre-filter, Dyno jet jet kit, fmf exhaust, hotcams camshaft, and new bearings. Who do think would win in a drag race? also let me know what else i could do to get more speed and power out of my machine.
