A fork brace can help you avoid this in the future, and make the front end feel alot better in turns.
Speaking of looseness, a little tip from an old racer. Don't overtighten the bolts holding your clutch lever or brake lever to the handle bars. Wipe a "super thin" coat of STP oil treatment on the bar under the mounts and then tighten the mounts just enough so they stay..... but can be twisted on the bar using both hands.
This way if the bike goes down, instead of breaking off a lever, the mount will just twist on the bar. If you ever had to hobble home with a broken clutch lever, of faced the danger of not having a front brake lever to use after a spill this might help.

I've had to pry the clamps open to even get the tubes to move a fraction of an inch. Once these things are bolted to specs they tend to hold the fork tube enough even after the bolts are removed to not just slide up like that. Ask anyone who's ever replaced their fork seals. They wont just slide on you...but then, I don't know how much you weigh 400lbs?...I have done it my way, more than once on more than one motorcycle without an issue

If KM`s method doesn`t work for you, this is what I did. Put a piece of plywood under the engine and jack the front of the bike up just enough to take the weight off the front tire. Loosen the 4 pinch bolts on the fork clamps and get a strong friend to sit on the bike and hold the handlebars straight while you squat in front, grasping one fork tube in each hand, and twist them back until the tire is straight, and perpendicular to the handle bars. It does require considerable hand strength, but you don`t have to be a gorilla to do this. If it is too hard for you to twist them back, loosen the pinch bolts a little more and try again.
Torque the top clamp bolts to 14.5 ft/lbs, and the lowers to 18 ft/lbs. Take a test ride.
Refine adjustment if needed.
If you loosen the clamps without taking the weight off the front tire, the fork tubes will tend to slide up in the clamps. Then you have two adjustments to do.

No dirtbike riders here? This happens alot when you dump your offroader, and the fix is wheel up to the nearest tree, (pick a big solid one, not a skinny wiggly one) put the side of the front tire against the tree and with all your weight shove the handlebar. (If the bar needs to be moved to the right, put the right side of the wheel against the tree, if it needs to be moved to the left, the left side of the wheel touches the tree)
Usually a few good shoves do the trick....as the tree ain't gonna move and something has to give. No use asking someone to "hold the wheel" unless they weigh 800 lbs, and holding between your legs only works on bicycles, not 500 lb motorcycles.
This is refered to in motor parlence as having a "tweeked front end" , lacking a tree , the side of a large SUV"s tire works well. In theory you can loosen up all the clamps holding the upper fork tubes, and try the shoving it back while someone strong holds the wheel, but if the forks slip up you then have another issue to try to deal with.
The tree works 99% of the time.

|flitecontrol||I'd start out trying to straighten it the same way you did as a kid when the wheel and handlebars on your bicycle got out of kilter. Put the front wheel between your legs and give it a good twist. If that doesn't work, go with kay's suggestion.|

|baldy||I would take the handlebar off and lay it on a flat table to see if they are bent. If it is, a bench vise with something soft holding the handlebars you should be able to streighten them. Quick and easy check before messing with the forks.|

|kay||loosen the four bolts that hold the upper fork tubes in place and have someone hold the front wheel straight turn the handlebars while you're setting on the seat. Tighten the bolts back. ...may take a few tries...|
