What year CRF?
On my 05 it was compression on top rebound on bottom. They also has the air Bleeder screw. You will know wich one that is because it will loosen, not click, if you turn it to the left. You should be pulling the air screw after every ride to keep your forks damping consistant. Just like the last guy said. If you Havnt adjusted them before. Go all the way in with the Adjustment a screws. Counting the clicks as you go. Make sure the compression is the same clicks out on both sides. Same goes for the rebound. There might me a rubber plug in the hole on the bottom of the fork. So you will have to remove that before you will be able to get a small flat head screw driver in there to adjust the rebound.
