Officially, CSC did change the valve check/adjust intervals to 500, then 5000 thereafter. This was after they took that 5000 mile Western Tour and saw very little valve wear. The new recommendation assumes that you are using the new 0.08 mm gap recommendation (instead of 0.06 mm). If you set a smaller gap, you should check it more frequently.
For myself, I'm going to stick with a 2500 or 3000 mile valve check until I am confident in a longer interval.
