Fork oil questions

Q: I have a 1968 Triumph T100S and want to change the fork oil. I have taken the drain plugs out of the bottom of the fork legs and will let the oil drain for a day or so. For refilling, I have a few questions: I assume I take the nuts off at the top of the triple tree. My manual says to add 190cc to each leg. Do I just pour the oil in the top and replace the nut? What oil do you recommend to use? I have Harley-Davidson fork oil from my old Shovelhead days left over, would that be OK? Some people have advised to use ATF transmission fluid, but I don’t want to mess this up.John Schaub/via email
