Did you start work after a run, could it have been hot, and therefore increasing the internal pressure?
Not had mine long and normally do this sort of maintenance in the spring so I'm not familiar. But just a thought

take it easy :) I'm using a torque wrench

The engine was cold and automatic

Haha, gooooood, good. I didn't at first, and so I caused all sorts of problems. Keep us posted!

Suspect the final drive pressure hold is normal and common on the VFR and other models.
The VFR final drive unit is NOT a vented like older final drives that had fresh air not completely water tight vent on the top.  The Goldwings were not doing water crossing.  Yes they were rain tight not not subversion tight.   The vent on older models were on the very top of the unit....see pics

Remember my FJR1300 had a vent too.

Did you start maintenance after riding? My drive shaft stays hot a long time afterwards, there must be thermal pressure buildup inside if there is no vent on the VFF1200X??

I serviced the motorcycle in the cold, I have not ridden it for a week, so do you know how to change brake and cooling fluids into DTC versions? or is there an instruction here somewhere? because there are no videos on YT
