My box had thixotropic grease in and the roller bearings were very badly worn when I stripped it for inspection and some pinions were showing rust damage. The box had clearly been worked on when the bike was restored as the clutch output side had been nicely re-bushed. The bike has clearly done very few miles since restoration so I’m inclined to suggest the grease may not be a good option for bikes that are not used regularly. I know its not a scientific test though! The box didn’t even leak when subsequentl filled with gear oil 😀
