Your M housing may be big enough to allow air to escape where the smaller BXs and possibly Bs may require some movement to make the air move out and I think trapped air is the issue. :2cents:
I checked the oil level in the hubs tonight and after 9 hours they are still full. This has never happened for me so I'm thinking that leaving the plug out overnight worked for my M6800. Put some oil in, let it sit overnight with the cap off and finish filling the next day.
