    I would say you would probably drop 40-60 rpms or so and pick up .5 -1mph. Just from my experience.

    Also pull the flame arrestor out of your intake manifiold and you will pick back up the rpm's and gain a little more mph.

    If you do both of those mods I think you should see about a 1-2 MPH increase.

    Thanks guys, any tricks to get rid of the bow steer feeling in the chop? I had a Kaw 250x before and I must say it was a dream to ride hard in the rough water.
    Other Q, just how weak are the pump tunnels on the RXTX ? should I be concerned with the mods I have done so far?

    I would be concerned. I have basically the same mods as you and mine cracked at 21hrs. It has been repaired and re-inforced and now at 78 hrs with no problems. Better safe than sorry.
