I removed the resevoir last night and notice the clutch fluid was very dirty and even had some particles on the bottom of the resevoir. I had changed the fluid about 5 weeks ago so I was surprised to see this. I drained the system and put new fluid in. The only slight problem I noticed today is the bike does not idle very well when in gear and the clutch is in. Any ideas why the fluid was so nasty and is it common for the bike not to idle in this situation. Other than that the clutch worked fine today.
