I've got an issue with the clutch on my 94 900ss - and it does not appear to be the usual slave cylinder leaking. What happens is I squeeze the clutch lever and it operates the clutch (duh!) but if I pull / release lever in quick succession it seems to go into a hydraulic lock where the clutch lever is out but solid. It does not let the fluid back into the reservoir - it slowly fills the reservoir again (over about 20 seconds..) Or alternatively you squeeze the lever and when you release the lever the fluid "jets" back into the reservoir... I thought I'd be able to get a kit of seals etc and rebuild the lever but unlike the integral reservoir lever I can't find a kit and there is no "exploded diagram" of seals etc shown here. https://oem-parts.hu/en/parts/ducati/1994/900-ss/handlebar-dm-012263-handle-bar Is it re-buildable ???
