Just purchased an 07 Phazer fx. (Going from a 07 Polaris 550 fan.)
The sled has already had every possible update from Yamaha and has just over 1000 miles on it.
What a different ride. I have only put about 5 miles on it around the house, tomorrow will be the test.
I set the rear spring pre-load to medium and the rear suspension damping to aroung 6 clicks from max. The spring seat length is around standard, maybe a little toward harder.
I have not had time to mess with the fronts.
I am confused on what the front rebound damping adjustment is for. Under what condition would I apply more or less rebound damping?
Anything I should look out for?

Slow speed is for little bumps, high speeed is for BIG LANDINGS
#1) When your sled is squirrely it almost always means your rear shock is not stiff enough and/or your center shock is too stiff (the two shocks are out of balance with each other). You must find a better balance between the two shocks. I might start by softening the low and high speed ajustement on the center shock. Maybe 1-3/4 turn out on high speed and 8 clicks on the center screw. Loosen the center spring so it is just held in place with the skid in the air.
#2) Run your rear springs in whatever setting keeps the rear arm off the rear coupler when sitting on it. Adjust the rear high sped nut to 1 turn and the center to 4 clicks. I like to slow the rebound on the rear, but this requires tearing the shocks apart and revalving.
Every sled wears differently so you should watch for the following signs.
1. Does your sled's suspension start to feel lifeless or packed up after pounding through more than 4 or 5 consecutive moguls or holes and then start to feel OK again after a few minutes of smooth cruising or after stopping the sled for a few minutes?
2. Does the skid sometimes just bottom on small bumps or holes when it really shouldn't?
3. Does the rear sometimes just suddenly kick up in the back....in situations where it did not used to?
4. Does the skid "clank" on medium to big jump landings even when you are landing fairly smooth?
If you answered yes to these questions then the shocks need to be rebuild before tuning can begin
Rebound is how fast the shock comes back from compression if the shocks feel bouncy slow the rebound down, if they don't seem to come back fast enough for the next hit speed it up. It may vary where you want it depending on the day.

I didn't think the stock Phazer FX center shock was compression adjustable. Also, I didn't think the rear had seperate high and low speed compression adjustment. I think you just have the clicker. If I'm wrong let me know cuz I need to go take a look at my shock!

Rear should have the clicker with two adjustments on it

Sweet!
I didn't realize it had high and low... the clicker is for the low speed and the other is for the high speed, correct?

I will have to take a closer look when I get home tonight and get it off the trailer.
Speaking just from memory and looking at my manual, I think I only have one place to adjust on the read shock. It is a piggy back device with a screw that you turn to adjust. The manual calls it "rear suspension damping force adjustment"
My front shocks have two adjustments, top and bottom.
One lesson learned already, the tall wind screen does not fit inside my trailer, glad I caught it before I ended up breaking the wind screen
For your fronts the top adjustment is compression and the lower one is rebound.

Thank you for all your input.
Well after the first 160 miles, I would say this is one fun sled. Coming from a non rider forward sled, this is a hugh change for me.
Cornering is different. I seem to get thru the corner the best if I am on the gas untilt almost the apex of the corner, then I let off to set the front down and burp the throttle thru the corner.
What amazed me was the ability to lift the skis off the ground, not only from a stop but while under power at lower speeds. This sled is all torque.
On a funny note, while on a long smooth trail, I had the sled up around 87/88 mph, I glanced down at the tach, 11,000 to 12,000 rpm, not what I expected.
One suspension issue I need to figure out, the rear shock does not seem to dampen the rebound. While I search TY 4 stroke, any one have any suggestions on how to fix the rebound issue?
