Loosen up all the fork pinch bolts, and the front axle nuts , and the top triple clamp nut so that all the nuts and bolts are just barely "snug" . Clamp your front brake and work the forks up and down. This should get any front end mis-alignment back to square. You might have to pull off the front fender to eyeball sight the front tire for squareness. Sometimes the front fender playes games with your sight. If your bars still seem tweaked, pull off the bars and lay them on a flat surface and look where the handlebars clamp to the mounts, if this area is not sitting perfectly flat on the surface you have bent bars.
