Just found this on my son's '11 RGU, may or may not eventually contribute to a wobble. He has been complaining of an intermittent rattle that sounds like something metal falling down a metal stair case. The engine stabilizer link has developed some play on the end mounted to the frame. I had been suspecting exhaust interference. With him sitting on the machine holding it vertical, I pushed an exhaust pipe (discharge end of muffler) firmly from side to side. There is a rhythm that the frame and tires will naturally wiggle and add to the side to side swing. While doing that we could hear a knocking and it felt like it was in the vicinity of the triple tree. The neck bearings had been tightened considerably at 4500 miles due to a wobble but eventually it was traced to a faulty front tire. The neck bearings are still plenty tight. Placing a finger on the bolt and rod end at the same time makes the play easy to feel.
On the 09 and newer machines, the new frame and engine mounts pretty well locate the engine with the bottom mounts and this link should primarily retain the vertical orientation of the engine/transmission/swing arm and rear wheel. If this has happened to him in 10,000 very conservatively driven miles, chances are good others will have this happen to them also. It is only a guess, but I can't help but think if this had gotten bad enough, it may have contributed to a new wobble at some speed or other. Especially for those with a hint of wobble, checking their engine link or links (on the older machines) might be one more thing to do. With the machine on the jiffy stand, we could not get the the link end to make any noise or feel any play. To check this the way we did will require some one keeping the bike vertical, with weight on the tires, not on a frame jack.
