Sand woops you want the bike to have a super stiff front fork. It sucks to race with both sand woops and rocks/roots, as the set up is the opposite.
Anyway, i dont have the clicker settings to tell you. But i will say you want the bike to skim accross the top of the woops, and to do that you will want it stiff.
For sandy wooped out desert races ive run 2" of preload in my forks. The old 'pile of washers' trick. It pushes the spring down, getting rid of a bit of 'sagging' and making it that much more ready for the woops.
Try using the rebound to stiffen things up for ya. Try clicking the top clickers 2 clicks to the right (clockwise) and then hit that sand woop section. Then try 2 more clicks. Repeat, till it is just TOO hard.
In general you want the compression clickers within, say 4-6 clicks of the rebound. So if you are WAY out there with rebound, then back it off and use a bit of compression to get the two closer.
Ball park, shooting from the hip from a guy whos never ridden an '07 TE 250: (i weight the same, and have a '07 with those forks)
5 clicks of compression (go to full counterclockwise, then click it 5-7 clockwise)
10 clicks of rebound. (right in the middle, get there however you want)
Most important thing of all with sand woops is TOTAL COMMITTMENT!
You have to have a fast entry speed. Stand up. Pin it, and if you are going fast enough you will skim over the top of em.
Slightly higher tire pressure is also good.
