Picking up on what Beemerguru said, is it possible your fork tubes are too high in the lower clamps? That could explain all the space you seem to have in there. There's a measurement for how far out of the lower clamp the tubes should extend; anyone have that on hand?
Edit: tubes should protrude 161mm over lower fork bridge
