    250sx power mods

    Does anyone know any easy bolt on mods for a 250 sx? Ive seen some people talk about a 350x top end, but ive never seen it done. Best aftermarket exhaust? Any other top end choices fora 250sx for better power? Or maybe some transmission or rearend gears for some better speeds? Any ideas would be awesome. Just curious
