I resolved a similar issue on my Y2K 1150GS. Though the bike would track straight, it seemed the handlebars were pointed slightly left while riding in a straight line. Thinking that by re-torquing the axle while the fork bracket bolts are loose, it might help re-align things if they are out. I loosened the pinch bolts on the fork bracket (#10), the pinch bolts and the axle. Retightened in this order: 1) Axle. 2) Axle pinch bolt right side. 3) Axle pinch bolt left side. 4) Fork bracket pinch bolts, being careful to tighten top and bottom on same leg evenly. When I got to the fork bracket, I noticed the left leg was lower in the bracket than the right. The difference was minimal, but I could tell by making a visual comparison in the machining in the leg above the fork bracket (circled in red in diagram). To remedy, before tightening the left leg I loosened the axle and pinch bolt left side, tapped the bottom of the fork leg with a plastic mallet until the two fork legs seemed even, then tightened up everything starting with the axle. Not sure if I had a twisted leg, or if the problem was a lower left fork leg or combination of both, but the procedure remedied my situation. I hope this helps. Cheers!
