This is not a which type question.
What colour should it be when drained?
Both my final drives have just drained dark grey/blackish while the transmission is still goldish colour. I've flushed both final drives to ensure they are clean inside, no residual old oil etc. After a couple of hundred kms, I drained the fresh oil again to find it's already darkening.
There is no bearing rumble, the drives are not running excessively hot after riding any distance. I'm just trying to figure whether I need to delve deeper.
