I asked this question ages ago, and got pretty much the same reply. At the end of the day anythings possible and I know Bings will fit and work. How much is then left for the motronic to do is a matter of interpreting a circuit diagram.
It will probably require a new loom and this will have to work with a normal oil temp gauge.
As to wether this is worth it is a question only you can answer.
I hate the injectors and have been rubbish from the start. I have always longed to go back to a straightforward setup.
There are plenty of websites with R11 with crbs on and I have a few German magazines with racing R11`s on carbs, I feel a properly setup carb is as good as any injector, and is only a way that BMW can ensure we dont interfere with the workings of the bike too much.
Best of luck.
If you ever do this let me know.
