Hydraulic Clutch Fluid Issue
Anybody any had issues with losing clutch fluid?
My reservoir seems to be losing fluid at a very slow rate. No drips or that on the ground I'm wondering if it's leaking into the engine somehow? or maybe leaking round the cap? Weird one. Any advice is appreciated. Thanks guys |

Sounds like the slave leaking into the area close to the drive sprocket. If you wet lube your chain then the fluid would get"lost" with the general crud around there.

I don't think the oem slave is servicable although I suppose if you found a suitable driver to engage with the big star, you could open it up. But then you'd have to source precisely the right o-ring to fit the cylinder (as it's not listed as a Ducati spare part).
Better, I think, use it as an excuse to upgrade to an Oberon or similar. |

I replaced it with an aftermarket slave that reduced the pull and is still working fine 20 years later but you could probably just replace the seal to fix it.

I'm talking tiny amounts. It's been topped up twice in 15 months

I’ve also had a high mileage (75k+) master cylinder seal fail, i could see a very faint splatter on the left side of the tank.

I had it on my Evo, I lost almost a reservoir full on a 300 mile day trip. I didn't notice til I got home, cleaned the bike and took the reservoir socks off and thought oh poo. I swapped the clutch slave to an Oberon but not really ridden it since due to the current climate so can't report much. The clutch slave looked pretty pants but didn't investigate just binned it

Yeah took me longer to turn the bike around than do the job with all the chains and locks to take off

Slave is easy to swap out just remember the hidden bolt under the sprocket cover usually covered in chain lube goop.
You could remove the clutch slave clean up and leave it outside the bike to see if there is a leak.

Not a problem for the Evo as it's just the three external screws that hold the slave in place. If I remember correctly, you won't even need to remove the sprocket cover.
