It's finally running again. I rebuilt the master and slave cylinders
and the clutch is 100%.
Thanks to Kyle's step through, and a little help from my Clymer
manual.
The only minor issues I had, were that I had some trouble with the C-
Clip on the master cylinder, it was siezed and my ring pliers the auto
zone version did not reach far enough, so I had to work it out with
WD40 and a jewelers screwdriver until I could grip it with a
needlenose and tear it out. The slave cylinder was just as bad with
the oil seal being broken and the metal insert was rusted fast and had
to be dug out in much the same manner. The amount of hardened material
in the slave cylinder was astonishing, I wonder how the thing worked
at all.
Oh and I did the sightglass fix too, I had a machine shop measure the
opening for the sightglass, > 16.7 mm.
I purchased 3 (minimal purchase) replacement sightglasses "watch
crystals" 16.7 mm, and I also used 5 minute epoxy (dries clear) from
Auto Zone.
The epoxy although it dried clear, is just a little cloudy, this
leaves a little bit of a cloudy ring around the edge of the glass. Not
quite perfect.
If I was to recommend it, I would suggest to used a toothpick as
opposed to the Q-Tips sticks I used for an even finer application of
the epoxy.
The result, in my opinion of course, was well worth the little extra
trouble. I plan to touch up the paint as soon as I get a few hundred
miles on it.
If you know someone who needs a sightglass let me know, I've got 2
extra for $4 each, free shipping.
I'll send a pic in a reply in a few minutes.

I have a recently purchased 1984 CB650SC, it's been running fine
for a
few weeks, got the oil changed a few days ago, and new tires. and
since then I have noticed the clutch is starting to act up. It works
fine when the engine is cold, but once the engine gets heated up,
it's
tough to disengage the clutch. I have checked the clutch master
cylinder, it needed fluid, I added a little DOT 3, just as the book
prescribes. It ran fine on the way home, once I got home the clutch
again was acting like it did not want to disengage. Anyone know what
might be going on here? Could it be they used the wrong viscosity of
oil? Could overheating cause this? How about the slave cylinder?
There
are no leaks anywhere. I think the bike sat for about a year before I
bough it. I also thjink its been quite a while since someone checked
the master cylinder because the screws were seized up and I had to
tap
them both out. I replaced them with allen screws from a fastener
store. Any helpful suggestions out there would be appreciated.
Mike
