I hit something at 50 KPH with LF tire only causing the handlebars to jerk violently Left, as my body slammed the Left handlebar causing a violent opposing Right steer force. The result was mangled Left A arm and tierod. I replaced those and now my handlebars were misaligned heavy Right while travelling straight. The misalignment was 7" at the tip of the handlebar (14" difference between the 2 handlebar tips).
In the accident there was a heavy twisting force to the Steering Column, DPS unit shaft and the Pitman Arm. The steering column roughly measured OK. I replaced the PITMAN ARM ($90) and that corrected half of it. I then replaced the DPS UNIT ($2000) and that fixed the rest of the misalignment. Note: the DPS unit is not repairable; thank you to these gear heads who prove it!
< PITMAN ARM: I wasnt able to do that until I bought a new one and setup a jig by threading a long bolt into the DPS unit housing in the vice and compared them.
< DPS UNIT: I used the pitman arm and a level and a straight edge. Put the pitman arm in the vice. Marked the blind splines with yellow paint. Put the strait edge across the blind spline. You can carefully feel when it touches both sides of the blind spline. Adjust the pitman arm in the vice until one of the splines showed level. Then check the other spline and it should be level as well.
< STEERING COLUMN: Remove the pinch bolt from the lower spline. Find a long rod to go in the hole. Put the handlebars straight. The long rod should be at 90 degrees to the centerline of the machine. Its a rough measurement but it worked. (Mine was OK).
