Is there anyway to stop my fork from getting wind down. When I set the forks to 100mm travel I'm actually only getting about 80-60mm of travel. When I set the fork to 120, Im getting like 90-110mm and so on.

I have an 08 talas R which I bought about 2 weeks ago. I have tried putting more air in to the shocks in hopes it would counter act the wind down but it doesnt...

Would Fox be able to help me out with this issue? Or is this somthing I have to live with, with this type of shock?
