+ 1 on what slabghost said. I'd also get the rear wheel off the ground and check for side to side play in the swing arm. A lot of handling problems can be caused by something going on in the rear suspension. The fork brace was designed to control some of the flex in the forks which should improve handling and remove one of the problems that could cause front end wobble. The proper way to install the brace is to loosely bolt it into position, loosen the four axle holder cap nuts, make sure the letter F and arrow is pointed forward on the caps,bounce the front end a few times, make sure end of axle is flush with edge of right cap, torque the two front nuts, then torque the two rear nuts. Don't be alarmed if there is a gap left on back side of cap. bounce the front up and down a few times again, then tighten the four fork brace bolts. I couldn't find torque spec for the fork brace bolts but I doubt that it would be more than 20 ft pounds. Maybe someone else knows the torque spec.
