passenger vibration

[Claybone]

I have an '06 HD Dyna Wide Glide. I find the ride to be smooth at all speeds. However when ridding 2-up my wife complains of teeth chattering vibration. I'm just not feeling it. The pegs are tight, the sissy is properly connected. Does anyone have any ideas/suggestions on what to check next?

I think it's just that it's a little rough back there on that not so padded seat. Try a sundowner passenger pillion. If your not feeling it I doubt it's any thing mechanical but it never hurts to checkout your bike from head to toe once in a while anyway.
