Can someone please tell me what the fork oil level should be on a '99 Ducati 750ss. I just installed some gold valves. These are just your run-of-the-mill upside down Showa forks. The race-tech instruction are generic and suggest 80mm from the top without springs, and damping rods fully compressed. This seems high to me. I've also heard 120-140mm. Right now I've got them at 130mm. Can I even tell a difference between these figures? Thanks!
