and most importantly-you MUST have the correct fork & shock springs BEFORE you attempt to adjust anything.
What is your weight? What fork & shock springs do you have? If the bike is not properly sprung for you/your riding weight, fix that FIRST. Once you get the springs right, then you can go through the clickers. Also, having someone else set your suspension for you is setting yourself up for headaches. How can someone else, who does not ride like you, or even ride the same bike as you, have an idea as to what you need suspension wise? Even after having a pro set up your suspension you will still need to make final adjustments yourself after riding the bike.
Step 1. Get correct springs for the bike.
Step 2. Set all clickers back to factory adjustment as per your owners manual.
Step 3. Ride the bike long enough to break in new springs.
Step 4. Analyze what you like about how the bike rides, and what you don't like.
Step 5. Make small changes-only on one component at a time. Ride some more and analyze how the feel of the suspension changed based on your adjustments.
Step 5. Make more small changes.
If you reach a point where you are as soft as you can go on compression settings and the bike is still too harsh, you may need a revalve at that point. Likewise, if the bike is too soft even with compression settings at the hardest adjustment point, you may need a re-valve.
It is very likely that with the correct springs you can find the adjustments that you like without revalving your suspension. However, in the case where you are attempting to use an MX bike for trails, or a trails bike for MX, you will most likely have to revalve in addition to respring.
I recently revalved the front forks on my CR250 for something better for woods type riding. My bike went from a jack-hammer off-road to a much smoother riding bike that did not fatigue me in 1 hour like it did before. I got advise from ThumperTalk about how to do this. Not saying that everyone should tackle their own suspension, but I am saying there is no "magic" to doing it yourself. Just have a good coach and you will be fine.
Knowing what I know now, and having educated people willing to help me, I would never pay someone else to set up my suspension.. Well, unless I just did not have the tools, and/or time, to mess with it myself that is. I can understand how some people don't want to make the commitment in tool purchases to do these things.
