Hydraulic Clutch
« on: January 23, 2009, 12:36:39 PM »
Anyone had experience bleeding a Hydraulic clutch? I've got a CB650 and the clutch is only active in the first half inch of pull on the lever.

It has new plates and I've attempted to bleed it several times

Do you mean you go from slip to full lock up in the first 1/2 inch, cos if so i think that would be right

Yes, but it seems I have little control, it still seem on or off, there is slip but no degreesof slip, if that makes sense

Yup, that makes sense, hydraulic clutches were only just starting when i quit spannereing so i cant be definitive but what you describe sounds more like parts incompatibility rather than a bleeding problem.

? are all the parts original off the same model

It's the US import model, and my local bike shop (DJ Bike Spares in Lincoln - Good guys) had a right time getting them, but in all dimensions they seem to be identical to the ones that were in  it. They are Pattern parts!!

John, if the hydraulics are working correctly, it's the same as having a cable.

Are you sure the clutch is OK/adjusted ??

If its working I really dont think its an air problem as that would just make it spongy and not work till the last bit by the bars---not in the first 1/2 inch.

Steve could be right in is there any mechanical adjustment at the clutch end?

I Have the Honda blue book manuals for the CB650 and the CB650SC addendum but not the later one sorry

Of all hydraulic clutches that I have come across there is a pushrod.Few bikes have a decent oil supply to them,so I usually remove the rod,clean it with some emery cloth,check for straightness on a piece of glass and lubricate with some fresh oil before replacing.
