Loosen the bottom triple pinch bolts (not the top ones or clipons). Roll the bike to a curb/step, and push it into the obstruction, then dive the forks by grabbing brake as it hits, using the momentum of the bike to compress the forks.
This will untwist the triples, so the axle is square to the direction of travel.
Do it three or four times, then retighten the pinch bolts to spec. Now you can look at realigning the clip-ons by swinging the bars through the travel side-to-side, and seeing if you have the same gap on each side. If not, widen or narrow one (if you have a new scar on the bar end from a crash, chances are you need to widen that side).
Then ride it. If it's still AFU, then your frame's bent.
