Okay, another newbie question. My front shock is bobbing like a pogo stick. It's all well and good on rooty trails, but when I go to ride a gravel road, I can't climb well at all because of all the pogoing. The problem is that I have no idea how to add air, which I'd like to do for a fireroad ride planned for this week.

Here's the fork I have: Rockshox SID Dual Air 2000

I have a high-pressure air shock pump (brand name unknown, given to me by a friend) that works fine on my rear shock, which has a Schrader valve.

From the manual I found on the Rockshox site, I see that my fork has a positive air and negative air valve ("dual air"). I understand that the positive air valve is at the top of the left fork leg. I am not quite sure if the negative air valve is at the top of the right fork leg (which appears just like the left fork leg) or at the bottom of the left fork leg, where there is yet another valve. So that's my first question.

My next question is how to pump them up. The directions say to pump them with a high-pressure pump with schrader valve. I guess something is missing, because the valves on my fork do not stick out, they are recessed with threads inside them, so I guess my pump itself needs a schrader valve to screw into them? I've looked at a lot of pictures of shock pumps online, and they all look just like mine - they end in a female connector that screws into a schrader valve. Or is my fork missing an adapter of some type? I bought the bike used, so who knows if it came with everything. The LBS pumped the shock for me initially when they were doing other repair work on the bike, but I have no idea how and don't want to take it there for something that should be an easy DIY task!

Here are a couple of photos - one showing the valve hole at the top of the left fork leg, and one showing the valve hole at the bottom of the fork leg:





I've done a lot of web searching but have not been able to figure this out and feel so stupid!

Thanks for any help you can give this clueless newbie to mountain bikes.
