I could not find this on the Tech board. Any pointers are welcome.

From tech board:
You'll get a lot of different opinions on this subject.  Some like to use a hand operated vacuum pump.  Some use a hypodermic syringe to suck out the fluid, some use the syringe to pump in the fluid from the caliper up.  Others install speed bleeders which is a bleeder with a check valve installed.

Simplest method with no fancy tools or equipment is to:

1.  Remove the reservoir cover (being careful not to spill any fluid).

2.  Attach a hose to bleeder and put the other end of the hose in a jar.

3.  Open the bleeder valve (unscrew 1/4 to 1/2 turn).

4.  Slowly squeeze the clutch lever to almost all the way and keep it squeezed in.

5.  Close the bleeder valve (screw it back in).

6.  Slowly release the clutch lever.

Repeats steps 3 to 6 until all the air is out of the line (or new, clean fluid is coming out the hose).  Make sure to add fluid to the reservoir as necessary so the reservoir never runs dry.

7.  Top off the fluid in the reservoir and replace the cap.

FOR GOOD MEASURE:  Pull in the clutch lever, tie it to the handle bar, and let it set overnight.

Depending on your arm length and agility, bleeding the fluid in the above manner may be a two person job.  It definitely is on an automobile.

Laure,
Thanks for the info. One last question. Where is the bleeder valve located?

Thanks,
Dan

Be sure to clean the reservoir first especially under that little tiny shiny piece at the bottom,  it will come out just pry under it gently

It is on a tube/hose on the back of the motor near starter and alt. If I remember correctly, access   from the left side (lay on ground).

Invest in Speedbleeders for your front & rear brake calipers and clutch bleeder. They have a one-way valve in them so you don't have to tighten them each time you pump the lever to prevent air from being sucked back into the system. You will not regret it.

For those of you who have used the Speed Bleeders have there been any problems using the steel in comparison to the stainless version?
