Just a technical note on throttle bodies in R1100, R1150, and I assume R1200 bikes.
There is an issue where the bronze bushings in these throttle bodies wear, and the throttle bodies rattle and get noisy. It used to cost something like $800 each to replace, but apparently this has come down a bit. However, there is a repair where the bushes are replaced, costing about $125 or so, however this is only a repair that will also wear. These repairs are done through Better Motorcycle repairs, I just had one done.
I've looked into replacing the bronze bushings with a roller bearing, as a permanent repair that should outlast the life of the bike, and hope to have a go at doing this soon as I get some spare time (hahahaha......). The RHS is the one that goes before the LHS due to the idle position switch offering some extra support on the LHS throttle body. Stay tuned, as this is a little modification job that can save a lot of $$ and help your bike keep running right. Why BMW put bushigns in is a mystery, because it is a real pain in the a$$ as these bikes get kms on them.
....just good info if you have noises you are not sure of.
