I just had the 6K mile service performed on my 2009 R1200RT at the local dealer. I watched the valve adjustment, but I didn't see the tech adjust the throttle bodies like he used to do on my '04 RT. I asked him about it and he said the computer performs the TB adjustments on the hexheads. I was suspicious of that, but he knows more than I do. I went out to Big Bend last weekend and traveled mostly 75 to 85 mph (4000-4500 rpm in 6th gear). The "buzziness" was uncomfortable over a period of time -- I need to do something before my next trip. Can TBs out of adjustment cause "buzziness" when the engine is pulling at higher rpms? I can let off throttle and pull in clutch (and coast) and the buzziness subsides when there is no stress on engine. Also, while traveling high speed downhill the buzziness subsides. So, I don't think the problem is tire balance or wheel alignment. I hate to even ask, but could problem be in the drive train somewhere? (Bike has only 8,400 miles on it.) Would very much appreciate the collective wisdom of this forum to help me problem-solve this. TIA
