Cat SX building shocks with the cut out in diaphram

[carlin]

Hi guys,

Can someone explain how you build these up becasue i have tried on many occassions now all i ever get is air and more air the shocks feel like crap.
Whats the trick to these, sorry for all stupid question.
Just it doesnt seem to work for me, so thier must be knack to doing them.

Any help would be great.

Also does anyone run anything on the shocks like o-ring to stop the shock from going to far up or any limiters inside the shocks
