Fork alignment

So I had a little mishap going around a corner a couple weeks ago. Front end washed out. As a result, it looks like the front wheel is a little out of alignment. So can someone give me some pointers about how to make sure the front is properly aligned? I understand you're supposed to loosen all the bolts, align everything, and then tighten from the bottom up. But how do you make sure the front is pointed straight? Any tips or tricks you guys can share?

I've actually had good results using a laser level. You hang the level over the bike and center the bike under it. I line mine up with the lock on the gas tank. It should also center on your rear tire. At this point it should be fairly evident if your front wheel isn't straight.

You can get a laser level cheap at HD or Lowes.

I just roll it up to a tree, put the side of front wheel against it and twist the bars to line up with the wheel. Then ride the bike to see if it needs more of an "adjustment" if not, re torque all the bolts one at a time....basicly eyeballing this, it's amazing how quickly you can notice if the bars are off....

What Ive done on many different bikes, is to loosen the bolts on the lower triple tree, then with the bike on a centerstand, stand in front, grab the bars, clamp the wheel between yer legs, and adjust by eye, then retighten bolts...

Not as accurate as Mike's method though....

Nothing like resurrecting a years old thread, so my apologies in advance. My bike was parked on the street, and the neighbor backed into it. The forks look fine, but the handlebars are off a little, and it rides just fine. I like Wolfies idea, and it's similar to some videos I've watched on YouTube. My question...a couple of the videos mentioned loosening the front fender bolts and brake calipers in addition to the lower triple. I'm not convince this would be necessary. What say you more knowledgeable than I?

Thanks

I don't see a reason so loosen the brake calipers. If you believe the handle bars are bent, it may be very difficult to get them perfectly straight again. I've found the best way to do this is to completely remove them from the bike and clamp them in a vice. Use a larger diameter pipe slipped over the bent side to wrench it back.

Perhaps your neighbor can buy you a new one instead? After all he bent it.

The idea is to release tension on everything that can hold the forks in the current position, since all you'll be doing to re-align is thrusting downward on the forks. Loosening the calipers doesn't seem like a big deal, if the bolts aren't over-tightened to begin with.

Fork alignment and bent bars are two different problems. I straightened my bars a while back by strapping the bike between two immovable objects (pickup and tractor), measuring the bars at fixed points, and pulling them straight with ratchet straps.

Is this the video you watched? This is the procedure I'll be doing soon, because my bike pulls to left and I know the rear wheel is aligned. I'll try to post back with results.

When you do this on the VN, you'll have to do it with the bars removed, because the handlebar clamp covers the top triple tree nut.
