Need some help as im going on a trip in two weeks on my FJ maybe ? Bike was running great till other day and the clutch stoped engageing and limped it home ! So I worked on bleecing the clutch and got nothing . Tried everything I know and can get it to pump up ! I pulled the slave off to have a look and pulled the lever and piston seemed to push out fine but when I put it back on fluid moves thru it thru it but actes like there not enough pressure to disengage the clutch and seems like there is a lot of air in it ! Its not the first time ive messed with somethinig like this but im lost ???? Is there a trick im missing on the FJs or something im over looking ? Befor I start rebuilding or replacing would like to get a idea where to start !!!!
Any help would be great and thanks for the help !
From what you said I would rebuild the clutch slave first. They take a lot of patience to bleed. Did you notice any fluid leaking from the slave ? Any leakage around the master ? RPM has new seals . Easy to rebuild.

No nothing leaking that I can see around either but I will look again today ! Is rebuilding the slave the same deal as rebuilding a caliper ? yea I looked at RPM really really nice guy first place I looked !!! Ill give the bleeding another go and if nothing works will get ahold of RPM Monday !

Please clarify your problem. You first state that the clutch will not engage, indicating a slipping clutch, then you say it will not disengage which would mean a problem with either the master or slave cylinder. These are two different problems.

Hein's got a good point, but if it is your slave or just a bleeding problem, I got this method from this forum and used it last time I serviced my slave when a regular bleed wasn't working.
Get a syringe and a length of tubing, put the tubing onto the bleeder valve, open the bleeder valve and inject as much fluid as you can into the slave and line. You'll have the diaphragm out of the master cylinder and the cover just sitting on the M.C. housing.
I'm not sure if this next step is required, but I then tie my clutch lever to the bar, and leave it overnight to allow any air bubbles to migrate up and out. I'll tap and wiggle on the lines every so often to help any trapped air move along.
Bleed it conventionally again in the morning and then close everything up.
If your clutch works for a while (a day) and then starts to fade again, I'd change the seals on the slave piston. It's not hard to do and the rebuild kit is only about $17. "Rebuild" is a strong word here, it's just changing out 3 rubber parts and a spring.

I recently saw such a syringe at, of all places, Tractor Supply Store...
FYI.

Thanks for the help guys !
After reading what I wrote I did kind of miss wrote things so I try again .
The clutch would not disengage and when I tried to bleed it after limping it home the lever would not pump up . I pulled the slave off and when I pumped the lever the piston would move out but as soon as I placed it on the bike it wouldn't pump up and air just keep coming out of the bleeder after a few hours of pumping it . Did some reading and talked to a few guys that know more then I and it always came down to the slave !
Im heading down to KY for a DTT GTG and really want to take the FJ as my Café build is not all the way done .
I took a shot and called RPM and couldn't wait so jumped on his site and ordered a rebuild kit . I cant say enough good things about Randy ( think that's it ) as its on it way and hope this will fix it . Again guys thank you so much for the help and a few laughs LOL
Will let you know if its a fix !!!
I had the same issue this spring, rebuilt the slave. Had to bleed the line a few times, seemed like it took a while for the air work ts way out of trapped areas. Some here say they wrap the clutch line with a screw driver handle to help the air bubbles move. Sounds like your headed in the right direction. What part of Ohio are in. I get into Ohio frequently to see family. And always looking for good rides.
Akron / canton area !
Our family is in the Columbus area, I do further north sometimes.
Mid-ohio vintage is a good time if you make it there at the end of july well worth the time ! And I rebuild the slave last night and bleed it then wraped the lever back and let it set over night . Got up befor work today and messed with for a few min then wraped the lever back down till I get home . I have 2 master cylinders I can use if need be which I might switch out just to be safe !!! Will let you guys know what happens !!!
:yahoo:
Lets see I rebuild the slave cylinder and that didn't fix it so only thing that was left was a master . Well didn't have time or money to pick up a rebuild now for that . Well made a few calls to some friends and found a good master off a ( cough cough ) honda ! Well worked on it and still couldn't get to bleed so on the phone I went again same friend has a mightyvac and that fixed it :good2: Now I have to ask where do I get one of those LOL
Thanks for all the help guys !!!
Alright! Happy ending. The mighty vac can be found at an auto parts store.

I had the same problem last year -- slave rebuild completely did the trick.
BTW, I found this in the old Yahoo group for FJ1100/1200s:
Yes [slave cylinder rebuild kits] are available. You can get them from Yamaha and aftermarket
manufacturers like K&L also make them. A rebuilt kit (a new o-ring and a new
dust boot) should cost you around $15-$18. The slave is pretty easy to rebuild,
but they can be a hassle to bleed. Most people have have good luck reverse
bleeding the system. That is, pushing the fluid up from the slave to the master
instead of the other way around. I personally use a large syringe to push the
fluid up, I then draw it back down, then push it back up. I repeat this until I
don't get any more bubbles (put Teflon tape on the bleeder screw threads to
avoid air leaking in or fluid leaking out). If you do decide to reverse bleed,
push the fluid extremely slowly or it will "shoot" out of the master cylinder
and make a mess (keep a wet towel handy).
