Completely draining the Final Drive Gear Oil

After a brisk ride, I drained and refilled my Final Drive (Differential) Gear Oil. I refilled with 180ml of Castrol Syntrax "Limited Slip" 75W-90 Synthetic Gear Oil (P/N: LBL 06674-00 B) API Rating GL-5 and MT-1. I also cleaned off a very small amount of fine slivers of metal off the Drain Plug Magnet.

I unbolted the rear of the Torque Arm hoping to tip the Final Drive Housing up/forward in order to help the oil to drain better - not much gained due to not much available movement in that direction but maybe not in vain?

I also repeatedly rotated the Rear Disc in the reverse direction and this did seem to "push" some of the residual Gear Oil out of the Drain Hole, mostly dribbling out. Hopefully this got most of the old Gear Oil out? Note: the Transmission was in Neutral.

I used a 60cc (=60ml) Syringe (3 times) to add the new Gear Oil into the Fill Port.

Lastly, I had to remove the Rear Wheel and unbolt the Rear Brake Caliper Mount Bracket for obvious reasons. I didn't remove the OEM Muffler. Instead I removed the Muffler Mount Bolt by the Rear Foot Peg, loosened the Muffler Exhaust Clamp Bolt, and removed the forward most Exhaust Shield Bolt. This allowed the Muffler to move outboard enough for the Tire/Wheel to slip through the gap. I torqued the Rear Wheel Lug Bolts to 44 Ft/Lbs using a "Star" Pattern.
