If it does I would think its a result of oil viscosity, drag, and tranny clearances.
Mine doesn't turn....
In fact; once when I had the swing arm and shaft out I stuck a giant screwdriver in the U-joint to make sure it wouldn't turn and flop around and break something, then made sure it was in neutral and started it.
I then felt of the U-joint and could easily tell it wasn't even trying to turn.
Then repeated the experiment without the screwdriver in place and the U-joint, which was now free to move if it wanted, still didn't turn
My XR650L Dual Sport Enduro would turn with out even blipping the throttle. Probably all that dirt in the oil, that poor thing got no love...
