Vids coming soon
As to the shocks it's not the caps for me (so far), as other people have described, but the bottom's which keep popping threads so the O-rings (AXA1184) are exposed. I then have to re-tighten the lower seals.
It could be user error. I'm doing them the same way I fill all my shocks..... 3/4 filled, bit of up/down motion to settle things and let the air bubbles rise, then top them up to just below the top (I try to match the gap with the bladder depth), bit more gentle up/down motion to get air out, leave them for a bout 2mins, then put the tops on.
There's a few leaks along the black in places - poor seal on the masking tape, but on the whole pretty happy with it.
