My bars sure didn't settle any that I noticed, but still you don't want to be realigning it again anyway do you?
If you pay for alignments, just set the height about where it used to be and go trounce on it a little (bumps and dips for 10 min) and then get it realigned
If mine settled at all it had to be in the first 5 min. (but I couldn't see any difference)
Been a month now and they seem to be in exactly the same place.
The bump stop clearances could be almost anything down there.

The only way I think the short travel of the adjuster will matter much is that if you were to go over a hump fast enough where the wheels would come off the ground.
It could cause the adjuster arm to come away from the adjuster bolt a little, but the blocks the adjuster bolts go through settle into thier saddle pretty well and don't move much.
I would like to think the bolt would still be in the right place when it came back down again. :D
