I ride lots of sand on the WR450. Nothing here but sand washes and high desert. I agree with UTVOLS, tires and suspension first.
But if I could have solid axles in sand I'd be better off. So I set the compression clickers in the middle and stiffen the rebound, more so in the rear. Seems to work.
Other than that I stand up, lean back, pull up on the handlesbars and grab a BIG FIST FULL OF THROTTLE . Speed is your best friend in sand.

I agree that speed is your friend in the sand, until you have to turn. The WR tends to get very distracted with ruts in the sand and when the trail turns, the WR wants to go straight.
I am not sure what you guys mean when you say suspension first. I agree with the tire, I have a Mich. S12 on my KDX that does a lot better. However, what to do with the suspension, I don't know.

Regarding Headshake I found the WR to be extremely stable even before I put my scotts damper on.
Set suspension to suit your weight you also need to regraese the steering head bearing as their is hardly any grease their and at the same time check tightness of steering head.
Regarding riding in sand I have also found that coming off a 2 stroke that when I turned in the sand that the front would wash out.
I was shown that with a four stroke you must ride more agressively in the sand as I have found if you tap off in the corner the compression pushes the front out more than on a 2 stroke.
drop it into the corner and give it gas.

> what to do with the suspension, I don't know.
The A#1 thing to do is to set the race sag:
Put the bike on a stand where the rear swingarm is fully extended.
Place a short piece of tape on the side panel.
Measure from the center of the axle to the bottom, left corner
of the tape. It doesn't really matter where you measure on the tape,
just be repeatable.
Put on all your riding gear, full camelback, etc. Whatever you
normally ride with.
Take the bike off the stand.
Remount and get into your normal riding position.
Have a helper repeat the measurement from the center of the
axle to the tape.
Subtract measurement 2 from measurement 1.
The difference should be 95-100mm. If it is not, adjust the
spring preload until it is. The Yammies seem to be pretty
picky about preload. My 98YZ worked best a 97mm. At 105mm
I had headshake.
Once you've got the preload set, lift up the rear of the bike
and allow it to settle under it's own weight. Re-measure from
the axle to the tape. This is "static" sag and should be in
the 10mm range. If you have less, you may need a stiffer spring.
More, you may need a softer spring.
Once that's done, for sand riding, you can generally run stiffer
settings than normal.
