In the meantime I removed the oil tank and flushed it out as well as removing the feed and return steel oil pipes, for flushing, to the oil pump.
I drained the sump of oil as well.
Two days ago I filled the oil tank ...

Removing the primary chain case cover revealed that there was significant clutch assembly axial movement.
Removing the kick starter case cover revealed that the nut on the ...
