    My clutch has lost pressure- just sitting in the garage? Why

    One of my bikes VFR Honda has lost pressure on the hydraulic clutch.
    Like it has no fluid ,
    It has fluid, and been no problem for the 2 years I have had it.
    It has no leaks that I can see.
    Reservoir is full. And the bike has not fallen over.

    So I bled the clutch fliud out and put new fluid in.
    Seems to be now working fine, ie. 3days later it still has good pressure.

    Q , Why should it randomly lose pressure?

    It possibly absorbed some moisture from the atmosphere.

    How long was it sitting not being used?

    One I had recently was the clutch slave... There isn't much fluid in the system, so you don't have to lose much, and I couldn't see any leaks...

    I had a similar issue quite a few years back. The issue was at the clutch lever.
    Sweat wipes off. Road-rash doesn't.

    90s Yamahas did this occasionally. I pulled the slave on my YZF and replaced the seal. I cleaned the slave out and gave it a light clean up with fine sandpaper. There was some corrosion at the lowest point. Water gets absorbed and is heavy so sinks. I change fluids but bike was 2nd hand so I was likely the first.
    I've been told. Dreaming`s free.
    Think I'll go, back to sleep.
    Everybody listen, voices in my head
    Everybody listen, do yours say, what mine says?
