There are some other recent threads about the hydraulic clutches. Basically, they feel a little different because the friction zone is not adjustable like cable clutches. The friction zone tends to out further than you may be used to... Most are over halfway out, or more. This can feel odd to people who are used to operating a cable clutch.
You bleed the hydro clutches to "adjust" them. It's really only making sure there is no air in the system, just like with brakes. There is no real adjustment available on the hydro clutches.
One thing to know is that as the clutch plates wear, there is less total volume in the system, and over time the master cylinder on the left side of the handlebar will get more and more full of fluid - not less and less as with the brakes. You need to check the level through the sight glass to make sure it isn't too full. It takes quite a few miles for this to occur though.
Harley specifies to change the clutch fluid every two years. I coincidentally just changed mine, and it was quite dark, which is normal due to the assembly lube they use to lube the system at the factory.
Also, the DOT 4 brake fluid that is used in the hydraulic clutch WILL DAMAGE PAINT, so cover all painted surfaces near the clutch or brake reservoirs before you take the reservoir tops off when refilling or changing fluid!
