You didn't say how many miles so I am assuming you have enough there may be some wear on the ride.
It could be tire wear causing the vibrations when leaning in a turn.
You could have some loose fasteners on the mounts causing the engine to shift during a turn. Have YOU checked all the engine mounts and bolts? I have had a problem with the service tech not checking things on my 1K and 5K services. Now I do all my own service.
AS Grover suggested, look at your upper motor mounts. A buddy of mine had his top mount break off the frame. HAve you noticed the motor seeming to lean when you turned as well? It's pretty easy to feel by hand but more difficult to see the upper mount.
Thanks for the info, I will check your suggestions when I leave to work. This is a great forum, if I could just figure out how to post high quality photos I could show you my bike!
