Jeff,
Sorry for the late reply.... no problems as of yet... close to 5,000 miles on her since October 10th. What I have been adding is accessory after accessory to the bike... the ONLY thing that I have not added from BMW's catalog is the ground lighting... I have added the fog lights, the top case brake light, all BMW bag liners, the GT tank bag... all after delivery, on top of the engine bars, the top case itself, Nav IV, side case protection strips, Gerbing's pigtail off of the battery, iPod connector cable. The latest was the Tech-Spec USA fairing protection kit (I only installed the side panel sections. So far, so good... this bike really is impressive, the torque and power delivery is intoxicating... and interestingly enough, I have gotten used to the weight over my RT and GS. Tires are shot though, I upgraded to PR3's over the stock Bridgestones... I hear better tread life is to be had with the Michelins... hope that helps.
