I've been trying every which way to get this stupid thing out but I can't figure it out. EVERYTHING else is out of the TRAC fork lower end except for this. The Clymer manual simply says to "withdraw it" at this point. I know there's an o-ring on there which I presume is keeping it from popping right out but I have gone so far as to put needle nose vice grips on the damn thing and yanked as hard as I can and I can't get it out... I would rather avoid baking the o-ring after paint so I would like to remove it but I guess I'll risk it for the biscuit if need be. The "oil control orifice" (ugh, who named this part, gross) is this part: It's what the adjustment knob for the TRAC system attaches to.
