I got rid of the wobble on mine completely (tested up to 100mph) by
 
1) making sure I didn't have a death grip on the handles
 
2) lowering the windscreen back to the lowest position
 
I found that rough wind in my face and a hard grip on the very wide handles resulted in unintentional steering inputs. The high windscreen pushed the rough wind up into my face. With it low, the rough wind is at my neck.

He explained what he did... and then I promptly forgot most of it.  He mentioned that the default front travel was slim to nonexistent.  
 
I may have it on a piece of paper somewhere.
 
I'm 250lb, so sporty bikes don't tend to be set up for me out of the factory.
 
He suggested if I really wanted it to be perfect, I would need stiffer front springs.
 

Got a $30 professional suspension adjustment done today.
 
TOTALLY WORTH IT.
 
Then got caught in a hail storm on the way home.
