This is an ongoing problem with my 2100 America, it's in the shop right now, I called earlier & they told me that the tech felt no wobble. I asked to speak to the tech and he told me that he took it out a second time and it wobbled (between 30-40, 50-60), they were going to check the head & I suggested that they also check the rear alignment. That phone call was 3 hours ago & no word... I think they may have found something. The last time I took it in they blamed the tire pressure (It was 2 lbs low) and also blamed the Metzler thread pattern. I can't wait to see what they come up with this time. It's tough having one shop in town that knows Triumphs.
