Anyone had trouble with these diving the front excessively under normal braking and bottoming the suspension out?

Mine does dive a little, but not overly, probably about an inch or so. The back never moves.

I've only covered about 500 miles on mine, it's an 08 bike that I've had since the begining of February.

The front and rear suspension are adjustable - maybe someone's been'a fiddling with it for you ??
