Pulling left - another possible fix?

"I was looking at the bearings and pivot bolts for the swing arm and it looks like you can adjust them to make the swing arm move left or right"

Thanks, Gothlander, will have to take a closer look
 
That tire is a 225/55R16 Bridgestone Potenza Grid.
 
If it was much wider it might not fit my wheel balancer:
 

I'll sell you that hitch for less than I paid for it ($300+ in 2009). Plus I'll throw in the hardware to mount it. The front goes to your passenger peg perch. You need a bolt to replace the pin (I'll throw that in) and the stays bolt to the fender mount on the frame so you need a through bolts and lock nuts(and I'll throw that in). $200.00 plus you pay the shipping.
