Clutch not disengaging

[sevenfiddy]

Ok my bike sat for about 4 months, but was started occasionally, and was in a garage, not really in adverse conditions. Anyways, I went to go ride it today and the clutch wont disengage. When I shift from N to 1, the bike lurches forward and dies. When I have it in any gear (not running) and I pull the clutch in, the bike will not move. I can hear something moving inside the slave cylinder when i pull the lever. I did bleed the clutch, and the old fluid was dirty, and actually had tiny pieces of what looked like a rubber seal in it. Is it possible that a seal could have disentigrated inside the slave cylinder? Please point me in the right direction, I want to ride tomorow. Thanks

It's very possible you're right.The slave cylinder could have taken a crap on you.Is there fluid in the reservoir?Is any leaking down from the slave cylinder?Have ou pulled the clutch cover off to see if the clutch has any movement?

If you've lost a seal somewhere, that could definitely be the problem.

There is fluid in the reservoir. Its not leaking anywhere, and it was full when I checked it. Like I said, I did bleed it. No air came out but the fluid was very dirty, and some verry tiny pieces of black rubber or plastic were found. Should I continue to bleed the system until ALL of the old fluid is out and its spitting clear fluid? I havent pulled the clutch cover yet. Is that difficult? Do I need to drain the oil before doing that? Is there a sure-fire way to tell if my slave is bad, or do I just have to replace it and see? Are there any other pieces internally in the clutch system, specifically parts with a seal of some sort, that could have failed?

My dad mentioned this earlier. He said it seems like maybe the clutch discs were siezed together from sitting. Is that even possible? The bike hasnt been ridden in about 4 months, but it was stored properly and was started 3 or 4 times a month. Hes a mechanic from the oldschool, and at first his suggestion seemed rediculous, but at this point im entertaining all ideas

You're dad may be right.Pull the oil fill cap first and look in there with a flashlight while someone else pulls the clutch lever.You should see the clutch hat move a little.If it's not moving then you have a problem with either your slave cylinder or the master cylinder .I say this on the assumption that you don't have any air in the clutch line and there are no leaks.If these things are true then I would look at the clutch master cylinder on the handlebar as the culprit.

thanks, ill check that out today. Even if I can see the clutch hat moving, is there any definitive way to tell if the master or slave cylinders are bad?

If it's moving and you have no leaks then you have to assume it's good.If the hat is barely moving then you have either :
1) not enough fluid.
2) Bad seals in the master cylinder and fluid is bypassing internally.

so how much is the clutch hat supposed to move? mine moves maybe 1/4 inch at most. I was under the assumption that my clutch discs had welded themselves together. Is there a definitive way to tell if the master or slave cylinder is bad before i go tearing into the clutch?
