Here is a downloadable manual from elka : Owner?s Manuals | Elka Suspension
Your shocks have a knob on the reservour that adjusts the compression, turning it in increases compression, out less. Your shocks dont have rebound adjustment. They do have a threaded body for adjusting preload for ride height and body roll / softness or hardness. You just loosen up the allen locknuts and turn. As for your camber problem, i dont think your a-arms are adjustable. You may need a new one.

^^^^^agree.setting the preload doesn't change caster-camber.when compressed the only thing that changes is toe.{that's what couses arm pump}.your shocks should be set up for your ride weight and arms.alot of times people just buy shocks thinking they will work but if they arn.t set up right the stock ones work better.

WHAT??? How does that cause arm pump? Are pump is forearm fatigue caused from the strain of riding for an extended period of time. Muscle tension restricting the flow of blood in the muscles through your forearm and hands.

If your shocks have rebound adjustment(doens't look like they do) there is a small flat head screw at the bottom of the shock below the spring and above the mounting point. Rebound adjust how fast the shock returns to it's normal position after being compressed. There are 2 types of compression, high speed and low speed. (need more pics to see what you have) High speed adjustment is for when you take a big hit, land flat off a jump, hit a square edge, blast through a G out, ect.. The Low speed controls the compression from body roll and the subtle bumps and hits that your quad takes. Like landing a jump pefect on the downhill side in the sweet spot, that is low speed.

High and low speed compression have nothing to do with your speed, it is the speed at which the shock shaft travels.

if the shocks arn't set up right or are the wrong lenght when going over bumps the quad will toe in and out,which will take the bars and try to shake them out of your hands!!the only way to keep it straight is to hold on tight and keep compinsating because the toe keeps changing and trying to make the quad steer different ways.

Changing preload will most definitely change camber, it will change ride height, which will change what position the spindle is in while it's sitting. Don't believe me? Put your quad on a stand, and take a shock off. Move the wheel through the travel and watch how the camber changes, along with the tow. Caster will not change. Think of a rail buggy and how the wheels are tilted at the top in while in a sitting position. As the wheels move through the travel, they become more upright.

The a-arms aren't even full extended in the third pic, let those arms drop completely and look at the camber difference.
