kickstand swings too far forward?

My kickstand swings too far forward, which ends up with very little triangulation to support the bike... very unstable and leans too far.  A gentle push would topple it over.

I've tried different arms, but no change, so it leads me to believe there is an issue with the bracket.  However, there doesn't appear to be a way to adjust the bracket (metal stops), and I can't think of a way to correct the issue (modify the bracket without compromising strength/integrity). 

Any suggestions on fixes, or does anyone have an extra bracket laying around?

Thanks!

Valid question, but no, I believe it is stock.  Ride height wouldn't change how far it swings forward, would it?  I can also tell it is too far forward because the foot only rests on the back edge (not even close to flat on the ground).

Raising ride height changes the entire geometry of the side stand, but it shouldn't change the contact point forward and aft. It would change in and out.

If your side stand is steel you could heat and bend the stop or add material to stop the arm sooner.

A picture of the bracket would make it easier to decide.

The bolts which attach it to the engine case have been known to back out which will cause the condition you're describing.

If they go too long like that, they can damage the case.  Check those.  Also, the pivot bolt for the side-stand can oval-out the side-stand somewhat (depending on what year bike you've got) and that can also cause the issue.

Lastly, if I bike's been down, I've seen that cause the side-stand to be bent some which will also .....  yeah, you get the point.

Check those items and see what's up.  [thumbsup]

Bracket is steel, I'll have to look at this again.  Add material as in weld more on?  Hmmmm....that could be an excuse to go buy the welder I've been wanting!   [thumbsup]

I'll try to snap a picture tonight.

Definitely not the situation, I have torqued to manual specs with a torque wrench.  But thanks for the checklist item!

I don't think this is the case, I've actually tried three different "arms" (original, replacement from 620 that was too short, and longer cycle cat aluminum as I originally thought length was the problem) and didn't notice this as an issue, but I'll check again.

Hmmmm.... not since I've owned it, but I am the second owner.  This is possible, although previous owner didn't disclose any "downage" and no physical evidence that I can find.

It looks like I might be replacing the bracket.     :-\

Funny thing about the steel side-stands is that they don't really look bent by the eye...  unless you have another to gauge against.

Finally got some pics... I have now tried four different arms, and all have the same effect (two stock, two cycle cat), so must be the bracket.  Here are the pics:

Here is the bracket in question.  Nothing really looks out of the ordinary?

Here's how it rests on a flat surface.  Notice how only the back edge is touching:

Here's the original stock arm, again with only wear on the back edge:

Cycle Cat #2 arm with wear only on the rear edge:

View from above to show how little triangulation there is to hold up the bike:

Any other thoughts?

Edit:  Hmmmm.... why won't pictures show?  Added links...

that is actually normal wear on the steel sidestands,

My Cycle Cat was the same.  I ground some off the back edge so there was more surface contact, but I also wanted to shorten the stand a bit.  I've had no problems with the foward angle.

Was the bike ever knocked over or forced over while the sidestand was down?  Normally that would bend the stand, but I suppose it could have damaged the bracket.

Not to my knowledge, but that's the only thing I can figure.  I just don't want to buy a new bracket (they must be made of Italian gold or something [roll]) and still have the same problem.
