No clutch

[gages]

Geez I've picked up this old 84 1100 and she sat for awhile , I'm slowly going through her trying to get her to start , cleaned and inspected carb all good except for pin holes in the diaphragms with new ones to be ordered , a strange single wire ( see other post just below this one ) and now no clutch movement even though the clutch lever seems to be operating but I've never had a bike with hydraulic clutch ...any hints on what I should be doing to check correct operation or parts that just should be replaced ?
Thanks

Take off the clutch master and clutch slave. Open them up, flush them out, reassemble them, bleed the air out (hint: a MityVac is your friend) and see if everything works. No sense ordering parts you don't need.
Same with your brake systems. (excepting your oem rubber brake lines, replace those)

Clean, clean, clean, add fresh fluid, bleed, then go from there.

I don't comment much on mechanical issues these days, unless it's important or safety related but I'm tired of reading the above over and over.

Personally, I don't have a problem trusting my life to 30 year old brake hoses but there is no downside to replacing them and braided hoses work better anyway.
I do however have a real problem with the widespread practice here that it's OK to "service" your hydraulic system, the brakes anyway, and reuse the seals.

NEVER reuse hydraulic seals in your brakes and never try and clean up the M/C unless you have (not think you have) some idea of what you're doing.  I shudder every time I read of someone doing this.

I've seen brake hoses that are 50 years old, I've seen them with a 1,000,000 kms on them and I've never seen a burst one but I have literally repaired hundreds of failed master and slave cylinders!
It's a job you'll probably only ever do once in the life of your bike, might as well do it right. Seals are not that expensive.

On this occasion it is not my opinion but accepted good practice that anyone with approriate industry qualifications will verify.

   Hey Gages,
Are we talking about a clutch that will not disengage, like plates that are stuck together ?
You'd expect this with plates that have not moved in a long time.
There is not that much to go on in your post , but, you did say that the lever seems to
work.  Could you be more specific?  I'm with Noel as far as the hydraulics go. Be sure you can, before you do.

Some good hints there , I'll definitely follow the advice
Hey Earl I think it might be a case of stuck plates , , everything see,s to operate correctly except the actually clutch plates but I'll clean everything , take them out have a look and put it all back together with new seals
I do have a good idea on what I'm doing except for a manual to help me along but there's heaps of knowledge here so a few questions might pop up from me
Cheers
