to bleed them as in get the old oil out?
if you dont have a little screw on the top.. (if you do undo that turn the forks upside down and pump them) then crack the top nut with the forks in the tripple clamp, slide the forks off the tripple clamp remembering to take the front brake off.. and undo the top of the fork, watch out there exessivly long plug/bolt and may be under a little spring tension so be wary a little bit.. take the cap off and pull the spring out remembering where the spacers are... and put them somewhere clean (dirt will stick to them) turn the fork upside down and pump them it takes a little while sometimes and you can leave them upside down while you have a coffie afterwards and a little more will drain out... warning it will be messy and will probably make you stick so have some rags, a bucket at the ready
i watched a video where he un done the top bolt and then un done an allen key bolt at the bottom and let it drain out... then just topped it back up through the top bolt... is in necessary to take off the fork?
