Item circled, in red. Im missing one in one of the forks. I just remembered since the last rebuild I did. I had to get them built up so I could ride it home from work. I reckon its something important, else why would it be there? Searched high and low, cant find them. Anyone got one knocking about? Haha
Not sure if the 850 forks are vastly different to the 9er but that looks like the "oil lock piece".
