Well I worked on my clutch slave cylinder last week then filled up the clutch...


Well, I worked on my clutch slave cylinder last week, then filled up the clutch fluid and started bleeding it, and ran into what seems a common problem, no pressure. Probably air trapped still. Couldn't work on it through the week, but I've been looking up some info and ideas, and will get back to work on it tomorrow. Hopefully can get it working again and have a nice ride.

I'm obviously not very experienced or inclined to work on vehicles, but I made my decision to do my best and learn as much as I can when I bought my Magna.

  • pump and tap, pump and tap, I even let mine sit overnight and kept at it. it will eventually bleed all the air out.

  • It takes me about 10 to 15 minutes then I'm good for the next month or so

  • By tap I am referring to taking a small wrench, I just use the one I have in hand to bleed with, and tapping the metal lines wherever you can reach them, in order to help the bubbles along. I do this at various stages, with the lever compressed and sometimes without it compressed. You may find it helpful to remove the tank so that you can have complete access to the hard lines. Make sure to never run out in the reservoir as you are bleeding, and pump slowly especially if you don't have the little metal tab that deflects the fluid from squirting straight up from the hole in the bottom of the reservoir. Wrap a / multiple rags around the reservoir, and try to have the bike level when doing it all. It's one of those fiddly things that you have to do, just keep at it you will get it all out. Once bled properly you shouldn't have to do it ever again. Christopher Davis you may have a pinhole leak sucking in air if you are finding yourself doing this as frequent as you say.

  • I'll check it out and see

  • Likely the slave cylinder is starting to go.

  • I think air likes to get caught because of how the line is routed. Looking at mine there is a high spot along the frame that would probably do it. My other thought was to run a hose from the bleed valve up to the resivoir and pump it straight through, topping off as required then just keep pumping till no bubbles come through the line. I haven't tried it yet so I can't say for sure how well it'll work.

  • Contrary to some of the negative things I've heard about them, I've had great luck with speed bleeders. I installed them on front & rear brakes as well as the clutch. I replace the fluids every spring and they've done the job for 4 years now. Just my $.02

  • The air gets caught at the master cylinder banjo connection because that's the highest point. So bleeding by loosening the banjo bolt does the job. There are banjo bolts available with a bleeder right on them, which makes it simpler and even easier.

    What I have done in the past is to C-clamp an old bicycle handlebar to a stud in my garage wall at a height and angle where I can attach the MC so the reservoir is higher than the banjo joint and then bleed normally. Very fast and easy, and by detaching the MC from the bike's handlebar, any spillage which might occur won't land on the bike.

  • Bleeding it by loosening the banjo bolt did it even though we messed up a couple of times.

    I think I'm still having trouble trying to get it back to neutral once the engine is running. It skips from first to second and back. I'll give it a ride and check back.

  • Actually went for a ride and it's working great now, sweet!
