The bike (a 1991 750 SS) has been sat on paddock stands for six months with a battery tender fitted. The battery has boiled half dry in the meantime, so I haven't tried to start it yet, but... There is no pressure at the clutch lever and the fluid level is low, but not empty. I topped it up and pumped the lever but it still feels the same and there are no bubbles at the bleed valve. What has happened do you think? This is my first Ducati, so all suggestions are gratefully received. I know my way round a tool kit (years of maintainence of older Japs and Urals) but hydraulic clutches are not something I've had an issue with before. Could a seal have gone in the slave cylinder and dumped brake fluid into the sump?
