JCZ is right, it COULD be your vehicle alignment. To repeat part of an earlier post, one of my employees used to be a wrench at SAC HD. He said 80% of the NEW vehicles he checked were out of alignment right from the factory.
Also in another post, I talked about the True Track unit and I REALLY found this to be a great help. In fact along with the progressive shocks I installed on my 01 SERG, It now handles very good. With no passenger, my buddy on his new 120 HD Race Motor and I did well over 125 mph for around 5 miles just outside of Needles on the way to Laughlin and everything was stable. (speed estimated, speedo buried!) We also did over 300 miles at around 105 - 110 and even with heavy winds that day, it was a steady ride.
Check out the true track for dressers at:

There is a tool required to make sure your lower frame cross member is propoerly aligned / staightened. We bought the pro model tool for my bud's shop here in Stockton and he could do the install for anyone in this area or I guess I could mail it on a loan basis to someone. You MUST use the tool once before installing the true track unit.
And before anyone asks, I am in NO WAY affiliated with true-track. I just like to share good things when I find them with everyone one this site because everyone here is so helpful when I need help [smiley=bigok.gif]
