tips on aftermarket for kfx400
Well if the exhaust/jetting/air box mods are not enough you might as well look into a 440 kit and just get it over with........... because those 400cc engines are about maxed for HP after the basic mods...... I mean you could get cams but why bother.... if you really need that much more power get the 440 kit.......
