I must have been lucky not to have any clunking or backlash from the HD compensator, it always felt solid.
Took ages to clean all the grease out of it though, it was well packed. Quite a lot had migrated right up the crank and into the stator/rotor assy. which lubricated all the bushes, a bit like a semi solid oil bath.
You might have a point with the lock wire though. The item in question is in picture 2, bottom row 3rd from the left. It is a big hollow bolt with an internal thread that screws onto the end of the crank.
