Im changing/upgrading the oil in my forks on my softail. I was told to run 5w, but when I looked on here alot of guys are useing 15w & 20w. I also was told to always replace the drain scews at the lower part of the forks because of breakage. My forks seem saggy, but I can see no signs of leakage. So hear are my questions. Can or should I use a heavier oil in the forks? Can I take the drain scew to the hardware store and match it up with a grade #8 screw so I dont have to replace it everytime? Or will that tear up the forks? Do I need to remove that set scew that is on the side of the forks when removing the cap/screw on top of the forks? I also was told that if I wanted to get my forks to stand straight up/fully exstended to put a piece of pvc pipe in the top, True or False? Thanks agin everyone, you have all been very helpful with all my questions and have made things a whole lot easier!!!
