Agree with above. That bike is plenty fast in its current form. Harshness might be due to servicing as mentioned above. Do yourself a favor and email Dave Moss. He will likely give you better info than a local shop with suspension setup. There is also an excellent thread from about a year ago about suspension setup on this forum.
For reference with bike setup, a friend started in novice with a cbr f4i, and with no mods at all, not even rearsets, he rode that bike all the way to the A group. He rides a fully cmra race prepped 675r now and is just a few seconds faster on his 675r when going back to back with the two bikes.
