That doesn't sound right. It seems the kickstand went too much down under G-forces. I would check the kickstand springs, and make sure it's lubed at the pivot point.
Weakened springs or a missing spring (one of the two which should be there) could contribute to the kickstand going down that far. Also, absence of the lubrication at the pivot point may create a packing effect when going over small bumps - essentially the kickstand moves down just a bit, but because there is no lube at the pivot point, it does not return back fully. Every other bump advances it further and further down, so it ends up being a lot lower than it's supposed to be.
There is one more reason to really check them: if the kickstand went down that much, it could trigger the kickstand switch. This means your engine may cut off right at the maximum lean. I don't have to go into details what the consequences could be.
Let us know what's the deal.
