Sorry for the late reply....
Yes, one 500 ml bottle is enough and they can be purchased on amazon (as mentioned) Z1, or maybe your local motorcycle shop. That is where I got mine from.

^^^ Good advice...
and use a second wrench on the other half to prevent twisting the clutch tube.
Some WD-40 or your favourite penetrating oil would also be a good idea.

Does anyone have experience doing this with the rjm pedal? I'm having a terrible time getting this to work. The first time opening the bleeder was fine, plenty of fluid came out. Each time after that (with pumping several times) less fluid came out .I have gravity bled it about 3 times and that seems to reset this cycle. After bleeding 3-4 times almost no fluid comes out and it takes about 30 pumps of the clutch pedal to feel like pressure is back. When I loosen the bleeder to gravity bleed, it sound like air is getting sucked back in. ?.. l messed around increasing the travel of the pedal but it doesnt seem to change anything. All l can think at this point is to reinstall the original pedal and try again. I've had no issue needing to pull the pedal up after bleeding.
Well, put the oe pedal in. Now I have to pull it up every time. Waiting on a helper before I attempt bleeding again.
I don't think the rjm pedal was a factor in this. But what a PITA this was. The one time we didn't lose count, it required 47 pumps to get pressure back in the pedal. I put the rjm back in and drove it around the block last night. Top of my head don't remember all the little adjustments to be made but, it engages about half an inch from the floor. Not taking the kids out like that. Will mess with it today then probably never flush the clutch again.

How are you gravity bleeding it?

I just flushed/bled mine as part of 2 yr maintenance. My process is this;

1) Suction out old fluid up to the min mark - I use a small hose on the end of the medical suction device (something like this
Amazon Amazon
) to get at the debris at the bottom of the reservoir. Refill then repeat until fluid in reservoir is all new.

2) Open bleeder at slave until fluid starts to come out, ~1/2 to 1 turn is enough.
3) Monitor reservoir and refill as needed. Usually 3-4 refills is plenty.

4) Snug (but not fully tighten) bleeder screw
5) Have helper slowly pump pedal 5-6 times then hold
6) Proceed with traditional bleed.
7) Do this about 4-5 times.
8) When satisfied, snug up the bleeder. DO NOT OVER TIGHTEN!!

Step #5+ is needed to replenish small amount of fluid left in the line by the slave which is not replaced by gravity bleeding.

In your case if no fluid is coming out then either there's air in the line and/or bleeder isn't open enough. Fluid doesn't gush out but does come out at a steady rate. This is probably 3rd or 4th time doing it. No issues with the above method.

I think I'm finally good to go. In my rage today I swapped the oe pedal back in. I borrowed a vacuum bleeder from advance auto, didn't work. I don't think the bleeder screw really seals through threads (topic for another day). The main reason I switched it back in was so I could tell when the pressure was sufficient to push the pedal back up. While I had the pedal out, I tried pushing the master "all the way in" as suggested in one of the countless threads I've read in the last 5 days. I'm really not sure if I was successful at this but I think it helped, even with the pedal out it is rather difficult. After the oe pedal was back in I tried gravity bleeding. This time fluid came out WAY MORE than ever before. Had a nice stream and even some bubbles in it. With the pedal back, it still required over 50 pumps before it came back up on it's own. So I went for a drive and everything seems good. Weirdly the oe pedal feels a lot more manageable than before. I think at this point I'm going to drive it as is for a few days while debating on taking it to the dealer to have "a professional" flush it.

So if the pedal stays on the floor just lift it up? Some other video said if the pedal is on the floor it means there is air in the system... well, then don't you have to pump it out? I heard lots of people having trouble bleeding the clutch. I don't see what the big deal is, is it really as simple as it looks in the video?

I've bled brakes and changed heads and swapped motors, so I should be ok right?

I don't see what the big deal is,

Lol... I hope you never do. I am no stranger to car repair either. But this was an unexpected PITA!! Never really found a good solution. In the end I took it my friend's garage, put it on a lift and we both tried bleeding it. The process didn't improve. Both our left legs were pretty tired when done. Kind of a "F this it's good enough" ending. I think the last idea I had was to replace the clutch master cylinder. Will probably do that next time I need to change the fluid.

Hmm... Why is it so hard to bleed the clutch???

I don't know. That's what was so frustrating about it. Some people have no problems. For others, it sucks. I couldn't really find a solution online.

Maybe I can do it in the street right outside the dealership so if I can't get it right I will just pull into their service entrance...

Try gravity bleeding? What exactly is the issue once the pedal is lifted up. Pedal doesn't get hard?

Yes. It literally takes 50 or more- push down then PULL up- before enough pressure builds for the pedal to come up on it's own. Gravity bleeding was hit or miss.

Sounds like a leaky master. That is, the cylinder is leaking internally where the seals don't seal well resulting in the inability to pressurize the fluid.

But why would the clutch function perfectly before bleeding was attempted? If the master was bad wouldn't it show symptoms before bleeding? From what I have seen people have perfectly functioning clutches but then they try to bleed and they run into unsolvable problems... It is a mystery to me because on all of my old cars I just bled like normal. Have a chump pump and hold the pedal down, I open and close the valve, do that a few times and it is good to go.
