I'm doing baseline major service items on the new-to-me 2007 R1200RT. I have ridden it about 700 miles so far and am really enjoying it.
Today was the final drive oil change and driveshaft spline lube. A FD oil change is an item that BMW originally thought would not have to be done for the life of the final drive and there was no drain provided. Problem is the life of the final drive on too many 2004-2009 R1200s was awfully short by any standard with a too-large percentage failing under 50,000 miles. This bike has 89,xxx miles on it and while it received regular dealer service this item had not been done in 30,000 miles, some 6,000 miles beyond the now recommended 24,000 mile service. The way the FD is partially disconnected and drops down 90 degrees down to drain the oil out of the oil fill port requires the end of the drive shaft to be popped off the FD spline. After draining and reassembly the FD oil is filled through the port that holds the wheel speed sensor.
I approached this job with some trepidation. Final drives and driveshafts in any machine, particularly BMWs of this design, don't last forever and this inspection could result in news that this used bike needs the $$ driveshaft replaced or either relief for another two years/24,000 miles. The news was good in that the pinion bearing and drive shaft U-joints passed inspection and the FD seals are not seeping or leaking. It's clean and quiet. Yay! I knew a used BMW would bring some risk for repairs. I did ride this bike twice prior to purchase but still........
When I was putting the tools and materials together I smiled to myself that I would be using Honda branded nitrile gloves and Honda Moly 60 paste on a BMW. I already purchased a liter of BMW branded synthetic 75w90 gear oil for the transmission oil change I did a couple of days ago and there was about 180cc of this oil left for the final drive change. I had some Honda 80w90 shaft drive oil on the shelf and was going to use that but there was just enough of the BMW stuff left over.
The next item will be a valve adjustment and throttle body synchronization. The valves are easy to do with screw and locknut arrangement but I will have to borrow a TwinMax for the synch.
