Help a light rider with his first air forks.

Hiya,
So i'm not the heaviest of guys - 9 stone 8 on a good day.
Forks are RS Revelation RLT, 140mm
To get anywhere near 20% sag (which is 28mm) I have positive chamber at 55psi and negative at 40psi. And ever then I'm probably not hitting that 20% but I haven't tried with gear on yet so it's probably in the ballpark.
Does this seem a bit low to anyone? I know the printed RS figures are way out but this seems a bit extreme.
The initial stroke of the forks seems very hard compared to my previous Recon Silver (coil) forks - is this normal?
Cheers.
edit: btw I am setting the sag via the bike radar approved way of standing in the attack position and measuring how far the o ring moves.

They are 2nd hand indeed. Could it be service time?
And yup, "attack position" is affirmative.
What is the positive pressure from the RS chart for your weight?
so try 55 psi in positive and 65 in negative and see how that goes

are you sure? the RS manual says for a firmer "XC orientated" feel then you up the pressure in the neg, and for a better small bump compliance you do the opposite.... I mean - doesn't hurt to try so I'll give it a shot tomorrow
More negative air pressure than the positive for a softer feel at the start of the stroke.

BTW dual air revs are lovely when set up right.

Bit peed off with Kona though, it was a ladies specific freeride bike and they put forks on that were not suited to lighter riders. Or are all ladies that want a freeride bike meant to be more 'well built' types?!!! IDIOTS :twisted:
And breathe.....

50 positive, 60 negative seems to give me the rough 20% sag i'm after with a plush feel, I reduced the rebound so it doesn't feel like its packing down.
I'll measure again with my kit on before this weekends ride but I think we're sorted!
Cheers all, now to learn how the compression control thingie works....
Motion Control on this fork is an adjustable compression damper. At one end it is fully open, at the other fully closed, which locks the fork out. You can set it anywhere in the middle, to progressively add damping.. This can prevent fork dive and bob. When locked out, the fork retains about 20mm of travel to aid traction. Note that some Poplocs do not allow you to make this adjustment.
But you also have Floodgate adjust. This is a blow off valve - you can set it so when the fork is locked it only moves on bigger hits. Too little though and the fork may not lock at all. it also has some effect when the MoCo adjuster is about 3/4 shut too.
Turnkey is an on/off lockout with no adjustment inbetween. The blowoff valve is fixed, but the fork is still designed to move slightly for traction.

I always thought this worked in exactly the same way to ProPedal or SPV - is that right?

Edit: I now see "Note that some Poplocs do not allow you to make this adjustment." - myth busted!
