Clutch bleeding ?

My book says to pull out a 'grub' screw and put in a bleeder screw/valve. then cycle the fluid as you would a brake line (simplified).
1) I am assuming a regular bleeder valve? Or do I need a 'speed' bleeder valve from Speed Bleeders Co.?
But what diameter valve? They are in different mm sizes if I remember correctly. I would like to be sure I have the right size around before cutting off a grub screw.
2) where is the line with the grub screw? what side do I start to pull apart to find it?

on the subject of brake fluid -
1) if I remember correctly, to see if two fluids are compatible, you can put a drop of one into the other and if it does not turn milky, they are fine. Yes? No?
2) to test for water in fluid you already have, just look to see if the fluid is clear or perhaps has water bubbles in it? Yes? No?

https://shop.maxbmw.com/fiche/NotesP...12330310_1.pdf This link will shed some light on the subject. The clutch bleed connection is secured to the right frame just above the foot rest. You can see it in the second picture in the area of the rear spring. Fitting size is 10mm.

10mm that helps. I hope Advance Auto has that size

Re: Clutch bleeding ?

I did not go to the link, but as I recall, I did not cut off the grub screw....rather, I remember it as unscrewing it at its base which is where the standard bleed screw then goes into. There was also the same odd contraption on the front brakes either on the K1200RS or the K1100RS.....easily removed and replace with a standard bleed screw for standard service.

Regarding the brake fluids, only a standard spec fluid would have been used by the factory and same by any reputable owner or shop since. The standard spec fluid will be compatible with any new fluid meeting these specs. No need to test if water is in that fluid, if it is brownish, ugly, or worse, flush it all out with new and be done with it. Gear oil does turn milky with water intrusion, not sure about brake fluid....

Re: Clutch bleeding ?

I just left the bleeder in the line and didn't bother replacing the grub screw, easier the next time around and no trouble with it for a dozen years or more.

One tip, when you pull the cover off the clutch reservoir, you'll notice a little hole in the bottom of the reservoir (same on the front brake reservoir). This lets fluid flow out of, and into, the reservoir. If you pull the lever quickly with the cover off, brake fluid will squirt out and land on what ever is in its way, and brake fluid is not a friend to paint. So, what I do is place a quarter over that little hole while bleeding the line. I remove it when I'm done and then top up the reservoir. Photo below. Also, avoid getting brake fluid in the threaded holes for the cover of the reservoir (I learned this the hard way.) If you do fluid will be forced out of those holes when you attach the cover and tighten the screws, and leak on nearby surfaces, again not good for paint.

I just spent 1 1/2 hr looking for this bleeder port - not there. I even took off the narrow long cowling on the right side just under the seat - nothing.

Can it be elsewhere? I'm stuck. Only thing left is to go to the shop for the job

Check this video on YouTube - pay attention at 1:15 (min:sec) where he shows original position where this hose is normally tied (to frame) under long right fairing.

Re: Clutch bleeding ?

Look at the crankcase cover on the right side of the machine. Next to the crankcase cover is the main frame, to the left when looking straight at it. The clutch vent line is zip tied to main frame in that area. Sorry can't find a picture.

Edit: Sailer beat me to it. I tried. The video shows it very well.

Smile Re: Clutch bleeding ?

well, found it. now to buy the bleeder. Auto parts store does not list a 'regular' bleeder buy just 10mm . I have to have more info on one. The video says "speed bleeder" so I believe they are actually referring to the brand - Speed Bleeder. Is this right?

So I will contact them to buy one asking for 10mm x 1.0 .

Re: Clutch bleeding ?

You could pull/remove the one from the rear caliper, (it's the correct size), use an ear plug to plug the hole while using it, reinstall when done. Won't lose any fluid...unless you actually push/step on the pedal.

Re: Clutch bleeding ?

Am I missing something? My old K1000RS bikes when you removed the allen screw from the fitting at the end of the bleed hose you could see a shiny ball bearing in there that is a check valve. The OEM grub screw worked in reverse of a normal bleed valve. You had to screw it IN to push on that ball bearing and OUT to let it seal for the let off stroke. I can see how a regular bleed valve or speedy bleeder could be used as it would seal rather than the bearing but if you unscrewed it too far the internal bearing would seal the device.

Re: Clutch bleeding ?

From memory...I use a speed bleeder for the process..yet have read somewhere(?), to file/grind down the bottom of the bleeder (which I have done)..not much, just to take the "tip" off of it. This allows it to function like a "normal" bleeder, where when snugged closed, the tip doesn't push that ball in, and allows one to actuate the lever a couple times without pushing out fluid till the bleeder has been opened/backed off.

No matter what, it's still kind of a three handed operation, yet once figured out, is a two handed exercise no matter what type of bleeder "valve" is used.

All I know, is when using the modified speed bleeder, it works like a "normal" bleeder.
Close to actuate the lever, Open to push fluid out, rubber band the lever to the grip while closing the bleeder. Actuate the lever a couple times, open the bleeder, actuate the lever, band it to the grip, close the bleeder....repeat till satisfied.

Might be incorrect, yet works on this side of the universe..

Re: Clutch bleeding ?

From memory... (yeah, me too) there is a fine groove around the tip of the speed bleeder to file down to. To be honest, I've been bleeding brakes for so long now I don't bother with the speed bleeder after I lost mine, and I can do all bleeders over the bike without help, just need to be careful and plan your moves.
