:coocoo: Hello,
I was just done washing my bike when i noticed how bad it sags. I was tightening the big fat nut on the shock (i believe thats the preload?) to take up some sag and it did but i still have quite a bit left. Now my question is: should i keep tightning the preload or what? My other question is that on the top of my forks i have: a bleeder valve that you push down and it releases air and a flathead screw. Is the flathead screw a compression or rebound clicker? There isn't a screw at the bottom of the forks, i guess that should help you figure out whats on top. The bike is a 2006 KX-250
Thanks

It's the compression adjuster on the top of the fork. The standard 06 Kawasaki KX 250 AOSS fork should have a air release screw abd compression adjuster in the middle ( you should see " H comp S " on the fork cap as well ). The rebound adjuster is on the bottom, it's consealed with a grey rubber plug.
