Thanks Dave, it's the alloy and rubber curved bit in the middle of your circle. The alloy body has 2 6mm bolt holes, slipper A in the balance chain system.
To the left is the shaft for the rear balance weight that buster wants.
The funny spring is the gear pedal shaft centre returning spring and the spring loaded rails is the cam chain autoadjuster mech.
There looks as if there is an angled plate in the circle also that I cannot see too well, a head bolt bracket that keeps rocker arm shafts in place perhaps ? Don't ask me which side lol.

Might you have a main bearing ladder casting from a scrap upper crank case, marked CCC, 250na, 210 prefix ?
Long shot I know but if you don't ask you don't find out.
I have an sd250 in which I am sure the slipper a is completely worn out as the balance shaft just rotates around and around.
It's complete and in one piece, it may have no balance chain crank teeth left for all I know.
The slipper A, the balance chain slipper, is for that engine.
But that delight is for the summer...
