it feels like something is shifting positions as I take off. At first i thought perhaps the chain, but I had a buddy sit on bike and adjusted chain. Whether chain is loose or tight makes no difference in the problem. If I had to guess, I would guess that a weld is broken somewhere. Tomorrow I am going to take it apart again and see if I can spot a break anywhere. Then depending on my findings I will take it to the dealer and get their opinion.

I've never jumped it (i'd kill myself) or even done wheelies.
