What is your ride height set at? I have my rear set at 8" at the footpegs and 8 1/4 at 22 inches in front of the pegs. 22 inches is where the frame is still flat just behind the a-arms.
If you are getting to much roll you might want to lower the height. Just make sure the front is 1/4 inch more then the rear. Measure the height with you on the quad standing on the pegs in ride position.
To raise the height tighten up the pre-load, to lower it loosen the preload.
The compression setting shouldn't affect the roll.
i'll try your suggestion, thanks! i honestly never se them up how i should, i think my rear a-arms bolts are 8.5 off the ground, and the rear is set at 8 inches, which is also the lowest it will go as my rear shock has two preload collars, which i havent seen before or since
compression on the front shocks is 3 from soft. rear is 7 from soft and a cant think of where the rebound is
