I took care of the front and rear brake bleeding no problem. Not so the clutch!
After hooking up my Motion Pro brake bleeder and then sucking out the old fluid from the clutch reservoir, being careful to leave a lil in the bottom, I refilled it and opened the lower bleed valve. I pumped the clutch lever and got a ton of air out of the bleeder. That's weird because my clutch was working perfectly before I stated. Now I can't get the dammed thing to pump up! I get a bunch of air coming out and a lil fluid. I closed the valve and tried the top bleeder. Lot of air but finally I got a clear stream. Back down to the lower bleeder. More air. I keep pumping the lever and adding fluid. Lots of air bubbles but it never runs clear. Back to the top then the bottom again.
It won't pump up and no matter what I do there's air. Where the is all that air coming from?
Help!
This worked perfectly the last time I did it.
Thanks Rhino.
Damn, I've been messing with this thing for two hours in my COLD garage. I guess I'll have to break down and buy a MityVac and mess with it some more.
For whatever it is worth Conrad- I have two hand- pumped brake bleeding devices (one MityVac and the other an all metal type of another brand) and neither one worked worth dirt on my C-14. The bleeders leak too much at the threads to maintain a vacuum with those things. The air aspirates types do the trick but you need an air compressor to use them.

Just had a similar problem. Went through all the motions. Ended up holding the mityvac hose right on top of the fluid hole over the piston and pumped the lever while sucking. Seem to clear the problem and got lever pressure back. must have got a particle of dirt in the mechanism.
Like I said, the brakes where a snap, no problemo and no swearing what so ever. I'm pretty sure that my swearing at the clutch is still reverberating in the garage. ..
Two years ago when I did this last I had ZERO problems.
I can understand the air leaking past the threads of the bleeder using a vacuum but where is all the air coming from using the Motion Pro valve? It's under pressure right? So if there was a leak at the threads shouldn't there be fluid running out? I can't get the dammed lever to pump up at all now. One time it did pump up after I closed the valve but when I opened it to make sure that all the air was out, I got more bubbles and then it wouldn't pump up again!
Exactly! For some reason I didn't have much of a problem on the brakes but PITA on the clutch. That's why I was thinking of trying teflon tape. Not sure if brake fluid will eat it up or not but I only need it to last long enough to bleed it.
When the master, calipers and brake line were changed on my other bike, bleeding them out was very difficult. Someone on another forum recommended that I hook small hoses up to the bleeders and raise them up to an elevated bucket. By doing this, I was able to work the micro bubbles out and not have to worry about opening/closing the bleeder 10,000 times. It worked like a charm.
guess it is maybe cos i am an old school geezer, but using speed bleeders on each orifice, both brakes and clutch, made the whole job easy for me. takes longer than a pump, but works fantastic on my baby. and don't need two or three people to do it!
just sayin
The powered vacuum systems work best and easiest on these bikes. Not cheap but not ridiculously expensive either. And it will save the nastiest words you know for a different project later on.... like adjusting the valves.
