Dropped CB500, alignment? - SV650.org

10-12-12, 12:37 PM

As you may have seen I dropped the CB the other day. Since then I have noticed than it wants to veer left slightly, I checked this by letting go of the handle bars and the bike veers left enough that I have to grab the bars again a couple of seconds later.

I'm not sure if it did this before the off and I'm just noticing it now or it was caused by the off. I'm going to check the rear wheel alignment but what else should I check?

The bike dropped onto it's right hand side at about ~10mph with the handle bars turned right if this helps. Everything looks straight by eye.

Thanks

Most bikes will ever-so-slightly pull to the left - camber of the road will do this.

What makes you think something is out of line? Are the bars straight in your hands as you ride? If yes, then it's unlikely anything is amiss.

Check to see if the forks aren't twisted.

From what I remember & i might not be right, just slacken the yoke bolts and bump the forks, not so that the fork stantions go through the yokes.

Summat like that, anyway.

When I'm riding down the A1 it pulls to the left slightly which I can't remember it ever doing, but it could just be because I dropped it and was looking for problems.

don't slacken the yoke bolts !!!!!!!

we lets clarify, if you're going to do this; leave the top yoke bolts done up tight, loosen the bottom yoke bolts and the wheel spindle (half a turn is more than enough), roll the bike forwards two feet, then sharply apply the front brake, do this a few times, if it's slightly out and you haven actually twisted the yoke, it'll pull everything in to line, once complete obviously tighten up the bolts you previously loosened.

Loosening all the bolts will merely see you slid the yokes down the forks, I seen someone do this whiles using the engine for the forward motion, funny as hell, but the face full of fork didn't amuse them as much.....

Cheers Mark.

If it goes to one side with your hands off the bars I'd say it's the rear wheel alignment that's out. How this has come about from just dropping it I'm not sure though, it's much more common to twist the forks in the yokes. I would think that fo the forks to be twisted enough to do this without your hands on the bars, you wouldn't need to ask if there was anything wrong with them, it'd be obvious. In my experience this comes from the back wheel.
