Motorcycle Repair: 85 honda 700, hydraulic clutch, air bubbles


Question
Ok, I understand you only wanting to discuss stuff related to what you own. But I have an 85 magna vf700. It has a hydraulic clutch. I bled the clutch for over an hour and go no pressure what so ever. I once read that I can clamp the hose with a pair of needlenose, pump the lever, and after a while I will get pressure. Have you ever heard of this? Or do you know of another way to re-pressurize my clutch. Cause I know that there can not be any more air in my line after an hour of straight flushing.

Answer
Hi Mike,
Bleeding the hydraulic clutch can be a challenge and can take a long, long time to bleed the 'traditional' way. I actually bled mine by opening up the bleeder screw on the slave cylinder and sucking the air bubble's out of the line. Just be sure to use attach a long clear tube to the bleeder screw, and don't swallow any of the fluid. If you don't feel comfortable sucking the air bubbles out, you can purchase a hand pump that will do the same thing.
A couple things to remember:
-Keep an eye on the fluid in the master cylinder and make sure it doesn't run dry
-If you stop sucking, be sure to close the bleeder screw on the slave cylinder so the air bubbles don't get back into the clutch line.

This method should get most of the air out of the line and you might have to bleed it the traditional way a couple times at the end just to make sure you are getting pure fluid (with no bubbles) out of the clutch line.
