How did the shock perform on your Fuel? Did you experience any of the behavior I've described?
I have the rebound turned fully clockwise - compression is set just a few clicks clockwise and the pressure is right around my body weight (I'm 170). The shock compresses fine - it just rebounds way too fast.
I've read in the setup manual that you are supposed to turn both rebound and compression fully counterclockwise before inflating. I'm not sure if I did that. I don't think that explains the way the shock is performing, but I'm ready to try anything.
Hmm... The Cloud Nine was fantastic on the Fuel. I set it at just over body weight for air pressure (175psi), and had both rebound and damping tuned so that it was firm, but not pogo-ing me out of the saddle. That's why I want to take it with me to my ETSX, but I reckon it will need a bit of fine-tuning to get it set right for the ETSX.
I haven't received the spacers yet mate, but as soon as I do, the Cloud Nine will go on the ETSX, and I will let you know how I go after having a bit of a fiddle.
In the mean time, I'd probably try setting both rebound and damping to their middle/neutral positions and making minor adjustments from there.
