Pull collar off and then remove 3 springs at top of bladder (seen in previous posts), now you can pull bladder off.
Doing this requires several precision tools such as a thumb and index finger and a small flat tipped screwdriver. These tools require proper calibration using 2 or 3 beers.
I however had ran out the night before and decided to cut the bladder off using a utility knife (well actualy only a blade cause I couldn't find the handle)
I did not proceed to modify the restrictive barrier (washer) but I did pull apart the mid valve this is what it looks like
