I understand why .... I got so fed up with trying to get mine to work properly I converted mine back to crown adjuster.
Two ways you can do it.
You can either replace the motion control damper with a non-poploc one, or you can disable the return spring in theMoCo and replace the poploc with a crown lever.
The cartridge in the pic above is simple to remove. You need to remove the cable spool from the top of the fork leg, using a 2mm allen key to slacken the grub screw in holding the cable in place, then slacken the grub screw in the golden gate blowout adjuster with a 1.5mm allen key. The gate knob lifts off its shaft and then the blue spool lifts off, together with the plastic cable guide and the flexi plastic spacer underneath it.
Now, use a 24mm socket to unscrew the damper assembly from the top of the fork leg. It's a tightish fit using O rings, so pull it up and wiggle it free without damaging them. The top of the fork leg is full of suspension fluid, so be careful not to lose/spill it. It's 5wt suspension fluid if you want to replace it, and SRAM techdocs will tell you how much you need (usually about 125ml)
The return spring for the poploc is a coiled affair, inside the MoCo cartridge. You can either simply reach in with a screwdriver blade and dislodge it from its stop housing (about halfway to two thirds down the housing) or you can unscrew the top from the cartridge (it's a reverse thread) and remove the spring altogether. Once the spring is disabled or removed it will behave like an ordinary cartridge.
Make sure when you reassemble it that you put it back exactly how you found it. It's possible to spin the compression valve shaft through 180 degrees and leave yourself without compression damping (voice of experience!)
Grease the o rings on the cartridge, wiggle it back into place and screw it back into the fork leg. Now, fit a crown adjust lever in place of the poploc assembly and there you have it.
Now for the fun bits. There is a market for poplocs. You'll get loads on
eBay for the poploc lever alone. (they're over £50 new) A poploc cartridge, together with spool and should get you in the region of 50 quid, possibly more. (they're £120 new)
A crown adjust lever alone will cost about £20.
Secondhand they are like hens' teeth, you'll do well to find spare ones. However..........
I just happen to have a SID non-poploc motion control damper sitting on my workbench, and I also happen to have a spare fork with a crown adjust lever in the process of being sold. It could therefore be your lucky day.
Let me know if you want them, it would be a simple task to sell your poploc kit in one and then fit mine direct. That way you stand a good chance of being up on the deal. If you live anywhere near West Yorks I'll fit it for you.
EDIT: Just seen you live in that London!
