A while back Texas Mac posted an article about the KK Sport.  I downloaded some of the useful bits.  Here are the disassembly instructions and the schematic.  Reassambly instructions in next msg.

Disassembly:
With the schematic and parts description in hand the receiver was disassembled
which was relatively easy.  Following are my notes from the process.  I’m not
sure if it’s required, but to be safe drift out the sear pin (12) and trigger plate
pin (21) left to right with the rifle upright and the muzzle forward, reinstall in
the opposite direction.
•        Push out the large finger lever pin (27).  The pin should come out easily
since it’s being held in place by a retainer spring (3) that snaps into a detent
groove around the center of the pin.  With the forearm removed the end of the
spring is visible.
•        Remove the finger lever (26) which includes the trigger guard and the
bottom of the receiver.
•        Drift out the trigger plate pin (21).  This pin will likely be different on
rifles with a trigger adjustment screw cover which my rifle does not have.  See
earlier comments.
•        Remove the trigger assembly.
•        Drift out the sear pin (12).
•        Remove the sear (14).  Be sure not to lose the sear plunger (not shown in
drawing) and sear spring (13) located in the top of the sear which can
inadvertently fall out.
•        Remove the extractor lever (29) and spring (28).  After removing the lever
and spring the extractor (30) should to be easy to remove since there should be
nothing holding it in place, but it refused to come out all the way with a
moderate amount of force, so I pushed back in and fully seated it in the normal
retracted position.  I expect there was a burr holding it in due to the close
machining tolerances.
•        Push out the breech block pin (2) that holds the breech block and hammer
assembly.  It should come out easily as did the finger lever pin (27).
•        Remove the breech block and hammer assembly.

No attempt was made to further disassemble the trigger assembly and
breechblock assembly.  Disassembling the trigger assembly should be straight
forward and easy, but I expect that removing and reinstalling the hammer into
the breechblock assembly could be a bit tricky due to the strong hammer main
spring.

Thank you very much that is what I needed.  It is hard to find info on the internet on these well built rifles.  Charlie
