YO Ho! Took my freshly serviced forks out last night for a thrash. I found the compression on them pretty slow, evenwith moco wound right out. I figure it can be one of a few things:
Internal difference, like oil weight, but there is nothing on the service sheet,
Tight new seals,
REstricted air flow due to uprated leak prevention on the top caps,
OR air setup. I gave jtech my weight, but they came back with pressures specified by rs in them, which result in maybe 5% sag at most. (125Psi). I am 72kg and ran 90Psi last night and didn't exceed 80% travel.
WHAt pressures are people running on rs? ANy thoughts?.
RS suggested pressures are silly high or at least they certainly were at the time of your fork. IIRC for me they recommended 170psi. I found 110psi right. For your weight, I would expect (for a 'typical' rider) you to be looking at 70-80psi which is borne out by your experience at 90pso.
Can Peterpoddy come along and remind me the correct sequence for putting air in these forks, please
something to do with letting all air out then start fill -ve chamber first
AS I suspected. Will fiddle the air a bit more, and in the correct orders.
Here's the doc you need.
The recommended pressures are usually too high so set your sag by sitting on the bike fully kitted. Always follow the correct + and - pressurisation sequence.
Let all the air out of the Positive and negative chambers, fill the positive first then the negative, or the pressure/volume differences between the chamber end up confusing issues.
If you ran 90 psi top and bottom and only got 80% travel just reset your pressures 5 psi lower in each chamber and see how you go.
This obviously depends on the typr of rding you're doing as generally you don't want to be bottoming your forks out on a regular basis, unless you having regular v.heavy front end landing (which I don't recommend 😉 )
Have a look at the setup guide with problem solver section at the bottom of each section if you get stuck:

I think this is the online version of the Peter Poddy doc...
