I was under the impression that the problem was with the stand folding back in if it wasn't far enough forward when down.
Someone at one point posted that their stand folded back up after it was down and holding the bike.......they then posted that the kickstand mod was to take a grinder and grind out a small notch near the top of the stand where it hits the stop, this would allow the stand to rest a little further forward before it hit the stop, thus the bike was not as likely to fall of the stand.
Someone else also posted at one point that the problem was significantly amplified if the bike was parked facing down a slight grade....which would make sense.
So.....I was going to notch my stand a hair and see how it works.
This is true... It makes it harder to collapse if it isn't "exactly" all of the way opened... However, it won't do diddly if you forget to put it down at all. DUR!
Also, I think most people do this mod so that the bike has less chance to fall while parked facing down hill some. I find that If I leave the bike in gear and then let it roll until tranny catches, this isn't a problem though.
