Has anyone else experienced their Ryker Rally or standard bucking when cornering?

I have a Ryker Rally and noticed yesterday when I picked it up that when I went around a left corner (not turn) the rear end felt like it was bucking or slipping. The speed doesn't really matter once you are above 20mph. The feeling is like being in a 4 wheel drive truck and making a hard turn when locked in 4WD. I took it to my dealer this morning and the tech rode it and felt it cornering both left and right and adjusted the front shocks all the way up and said it fixed it. I rode it home and though all was good and then all of the sudden it started again.

Dazed and Confused!!!
