I am currently riding a 2014 R1200RT and have a question for the forum specific to the water cooled motor. I tend to use the bike for both local work runs and longer tours of 4k Ė 6k miles. The bike has just under 20k miles and the motor seems to be progressively getting louder relative to the valve train. The issue has been ongoing since the 6k mile range, or that is at least the first time I asked the BMW techs to take a closer look at the motor. The valves have not required any adjustments over the course of the 6, 12 and 18 thousand mile services.
So directly to the issue. The noise essentially sounds like what you would hear from a motor with hydraulic lifters where one of the lifters was not getting enough pressure, thus the ticking sound (the motor does not have this design). The left side is more pronounced than the right to the ear. Now this is my first boxer motor, but I have been around several other bikes with the same motor and they are nowhere near this noisy. I recently purchased a RNineT, which is a different motor, so not a true comparison, but I can tell you there RNineT sounds nothing like the RT. Different oil viscosity and apparently different engine tolerances per the BMW mechanics.
Just past the 18k service, the dealer replaced the cams due to some wearing concerns. This apparently has been an issue with a few other units. All valves adjusted, new cams, still noisy. Maybe slightly better, but still loud and does not sound right to me and apparently BMW, because I continue to press for a solution and they claim to be opening a PUMA ticket (Iím sure I have this acronym incorrect). The ticket is supposed to be a technical request for more manufacturer support. I could be wrong on this last part, but that is how I understood the discussion.
Iím almost willing to trade the bike in for a 2016 but they donít make the Grey any longer so now Iím going to press them to fix the motor. Iím also not willing to let them sit on the bike for weeks to find a solution because I use the bike extensively.
Oh, I did leave out one piece of information. When started cold, bike sounds wonderful. Once the oil is hot, and bike is at an idle or very light load under 3k RPM's, noisy as can be. Annoying enough that folks next to me on an HD what to know what is wrong with the bike.....
Any similar experiences out there with this particular year ?
