What is the best way to bleed a clutch?

Get some tubing to put of the bleeder vavle on the slave cylinder. Put a little clutch fluid in a small jar and submerse the end of the tube into it.

Have your assistant pump clutch 3 times. Open valve, Close Valve when it's done pushing fluid out.
Rinse and repeat.
Every 3 times you crack the valve, check to make sure resevoir is not low on fluid or you will need to start all over again.

The fluid in the jar prevents air from being sucked back up into the system. Stop once you are confident there is no more air in the system.
