 In the video he pressurizes the boost chamber AND THEN he unscrews the bottom out valve. Is this the right procedure? Or should I unscrew all the way then pressurize and then ride around and screw in to my liking? Please help...

 When adjusting the bottom out on the dhx shocks (4,5,RC4), you are changing the air volume of the shock. Meaning that if you have the bottom out control fully out (counter clockwise) the air volume of the boost valve is at its maximum. When you dial in the bottom out control (clockwise) you are decreasing the physical air volume inside the boost valve (therefore giving the shock a higher or quicker rate of ramp up or non-linear quality).

The proper way to adjust this control is to adjust the bottom out control to your desired setting, then adjust the air to the boost valve chamber. Reason being, if you fill your boost valve chamber with 150 psi and then adjust the bottom out control clockwise, you will actually increase the pressure inside the boost valve because the air volume is decreased from this adjustment. So if you know how much bottom out control you like with your shock, dial that in BEFORE adjusting pressure inside the boost valve.

If you are curiuous about this, adjust your bottom out control fully clockwise, connect your shock pump to the boost valve and inflate to 150psi. With the shock pump still installed, fully unscrew the bottom out control fully counter clockwise. You will see that the pump will drop in pressure. Hope this helps.

 hey, just curious about setting SAG. should that be done first? or does it even matter? thanks.

 You want to set sag first as it will help with all the rest of your suspension settings.

 Hello Brule,

Do you know if i can use your guide for the dhx 4 air as well?

 The DHX 4.0 air is the same set up, just no boost valve to worry about - great shock!

 Thnx, i wasn't shure about the maximum pressure.
Shock works much better now. i changed the pressure from 75/210 to 125/220. No more bottoming out with my 220lbs.
