    the 400ex is naturally a torqy motor.... sparks x-6 system makes more power on the bottom than any slip-on system, ive personally had a x-6 and many other pipes on a stock 400ex, a 400ex with cam and 11:1piston and stock carb, a 416ex with 12:1 cam, port work and stock and fcr carb, and a 440ex 11;1 with cam and fcr carb the sparks worked GREAT in all of them and there was never a lack of bottom end and the more mods you do the more you will love the pipe.


    get the sparks

    does anyone have a dyno chart of a machine with a sparks on it by chance, i was looking at the dirt wheels test and it doesnt have one. i am curious to see how it actually stacks up vs the rest at different intervals like the test. say 4000 rpms and max along with the dBs and weight. the sparks site doesnt have one, i thought they did. steve
