I just had my 1200 service done. I didn't get a chance to drive it for long afterwards. Will look out for this in a controlled situation, but I haven't heard it until now. I do get some kind of a "whine" at around 40 mph from the drivetrain (driving straight), but I don't know where it's coming from exactly. I will check to see if it is still there after the break-in. The service guy is saying M drivetrains make all sorts of noises, and that I should drive it for at least another 1000 miles and then see.
Greg, did you go up to the redline after the break-in? If do, how is it? I'll do that today.
