you're correct. I didn't measure the fluid that I took out however it seemed about the same in both and it did seem to be about the same amount I took out. I used harley fork oil. Probably a mistake. I wonder if that is the same 5 weight oil that I took out. Hey Glider, while I'm writing, do you know if Harley aftermarket rear lowering shocks for the 2003 Heritage that were put on the bike at the dealer when it was new are adjustable. Seems like im bottoming out in the rear also when I hit a bump. Im only 225 lbs. That shouldn't be overweight.
