Sorry not a GS but 83 honda magna 750

[pinner]

My father has a magna 750 with a hydrolyic clutch. We refilled the resevior and bleed it but still no pressure. It's getting fluid in to the clutch but still no pressure. Any ideas?

Did it work before you bled it?
If it did, you've got air in the system

didn't work before. The PO said it stopped workin, he put it up for sale and baught a new bike.

what i've always done when bleeding clutches and brakes is let the pedal/paddle snap back forcefully when bleeding, it tends to work air bubbles out. works great for brakes and car clutches, i'm not sure about a bike clutch, but i don't know why it wouldn't.

i'd also check to make sure nothing is seized and/or leaking.

and check the bleeder and make sure it is totally closed. i've done that one

Never worked on honda, but if like other hydraulic clutches, you will need to bleed all air of line. Just like brakes, the air will rise to highest point which is near master cylinder. I have had good success bleeding by cracking open banjo bolt that connects hoses to master cylinder while depressing lever. Do this several times and then go about pushing fluid through lines. One other trick is to use a long nylon tube on bleed screw that will reach to master cylinder in a loop. Then you can leave screw open and pump lever till arm falls off. Check to see if the actuator for the clutch moves when clutch is depressed. Good luck.

If I understand you correctly, fluid is getting to the slave cylinder, but not activating the clutch? Are you sure the master cylinder is working? You should see fluid come out of the bleed valve at the slave with each pull of the lever. If so, then maybe the slave cylinder is frozen?

I don't know much about what's in the master cylinder, but I did pull the slave off of my '83 honda nighthawk because of a leaky oil seal and it looked pretty simple. You might pull yours and check the cylinder to make sure it moves. DON'T press the lever with the slave off the bike, but it's ok to press in on the cylinder with your fingers to make sure it's free.

Did You use a Mighty Vac.? What I learned when Brian Wringer helped Me change the Slave on the GSX1100 is that bleeding the clutch lines is near impossible without mechanical help.

Thanks for all the help. I will check the slave tomorrow and prolly order the mighty pump soon.

Any ideas?

It's broken.

I also might point out that the slave cylinder is the low point in the system, and thus collects all the moisture, mung, and little green men that sprout in elderly hydraulics of any type.

It might be well worth simply replacing the slave cylinder. That's what we did on Scotts GSX1100G, and it was a 1993 model with very few miles on it.

Adding a speed bleeder nipple wouldn't hurt either if you can.

Another vote for the vacuum pump.
