    i was suggesting them for someone to do, not something to actually do in your test. maybe exriders will do something like this one day and post their results. this is going to be a great comparison between a very interesting and talked about issue. steve

    I'll ask John to see what he thinks, but I suspect, that it would not be benefical, in this test, due to,
    I already have a few "Bolt-on" mods,
    that basically require a no lid / or cut-out lid, configuration.

    The "Control", on this test is going to be perfomed on a '03 400EX with,...

    Big Gun Full Header w/ Race Series Muffler, and Quiet core,
    Uni foam Filter w/ cut-out lid, and Outerwears Prefilter,
    Sparks +6 Timing advance key,
    Full tank of fresh 91 octane pump gas,
    Fresh Oil filter, and Honda spec oil,
    Valves properly adjusted,
    Stock piston, coil, sparkplug, rev-box, stator, etc.

    I'd LOVE to start off with putting on the stock muffler, airfilter, lid, and no +6 key,Just to see what it will be producing above and beyond a "off the showroom floor" set-up,...
    I'd be willing, and glad to do it, if there was more cash available to do a "Stock - to - Mods" Dyno test.

    BUT, that would cost more $$$ in dyno time, and lets face it,...
    Who do you really know, that leaves their 400EX, Bone Stock ???

    And for those riders that DO leave it bone stock,
    they usually are not the ones who are that interested in the performance gains of Mods, and Aftermarket upgrades.

    I dont know,... maybe I'm wrong there,
    but I doubt that it's really that beneficial to start it off with a bone stock Dyno run.

    x2....Im definitely gonna hold off on the 450 carb til after the dyno results.

    I really don't think you're gonna see any major gains. Maybe a 1hp increase ( hopefully at least 2hp). But the power delivery might be a little smoother with the better carb.

    Good luck!!

    sounds like an excellent idea.

    My only suggestion is to make sure you overlap the dyno results into a single graph. Two side by side doesnt show much. JMO

    cant wait to see the results.

    Mine is bone stock, rght down to the parking brake cable. It gets me where I want to go, so I dont' really care. I'm interested in performance all right. But I'm only gonna modify my 450R.
