Thanks Boggy, but my bike is not a G5 but the AVL in a C5 frame so it looks like the forks have to come out and drain them from the top.
Sorry, Boggy and TooseeveeYou are both correct
Tooseevee, I have clubman bars on my AVL and had to rotate my bars up to get the cables out of the way of the top caps. And one of the caps was really tough to extract. I wonder why you were so low on one side... Maybe a really subtle leak at the drain? Your forks aren't weeping at all from any other point are they? The fork seal replacement was a pain in the butt.
The C5 forks are 200 ml, the G5 forks are 265. I think the B5 are 200. The AVLs came with two different frames. The easiest way to tell them apart is look for the hot dog warmers, the tool kit and relay containers.Bare
