Help - setting up my dual air revelations

For someone of my weight the guide on the fork says I should use about 150psi in the positive and 150psi in the negative chamber. My lbs mechanic said to run the negative chamber 10psi less. I've done this but the fork feels so stiff, maybe it's meant to be like this as I'm putting a lot of weight on the fork when standing on the bike.

Just wanted to know, because I feel small bump compliance has been compromised for big hit compliance.

I'm around 15 stone and 6'5'' tall - should I run the forks at a lower pressure than 150psi?

    have you looked in the FAQs?

    Do it as there is a how too for dual air RS forks in there.

    and forget the numbers.

    You need to experiment with the negative pressure. I run approx 5-10 more psi in the negative chamber, this makes the fork more responsive over the smaller bumps giving a much plusher feel. Don't over do it on the negative though as you'll end up with brakedive.

    I run a lower pressure than recommended.

    As Pdid says try runnining 5 - 10 PSI more in than the negative than in the positive air. Running less, as you have found out, will cause the fork to be less responsive.

    I`d try running the postive a bit lower.I`m 14 stone and use 120 +,125-.
    Ignore the guide,stick a zip tie on the stanchions to measure sag and aim for 25% travel when sagged,sitting on the bike if you want them plush.
