fill the shock halfway than u go slowly up and down and set the shock somewhere to get the oil to settle it might take a while, then fill it up to the top and get the air bubbles out just like i met u can get the big bubbles out but its hard as hell to get the small ones out , than put the bladder on and get a screwdriver and push the center of the bladder and lift one side to get the air bubble out, you can have a little pressure going to the top to so much that it wont copress to the top at all and usally that will give u full rebond, do make sure that when u compress it to the top let it compress out and you do what both stocks to etheir compress fast or a little slow . you can get it just close enough and it would be fine. oh and dont overtighten the cap cause it will cause air bubbles and hyro lock
