Thought I'd give an update. When riding, I started to really analyze the position of the bars trying to ignore my different length arms and began to suspect that they are in fact turned to the right a bit (which makes sense as my right arm is the shorter one and therefore the bars felt straight... straight bars usually feel cocked to the left a bit because I have to reach further with my shorter right arm! Yay!)
So in the garage on the side stand, I got down in front of the bike and sighted back across the front to back edge of the front tire lining it up with the rear tire until I could see an equal amount of the rear tire on each side of the front. Once dead straight, I walked behind the bike to look at the bars and sure enough, they were very noticeably cocked to the right! Just to be sure the bars aren't bent/asymmetrical (which I actually think they are, one side is higher than the other), I checked the top of the tree versus the tank and it was definitely pointing toward the right.
Long story longer
I loosened up all the necessary components and straightened them out... which was rather difficult for some reason. But I got the bars straight, tightened it all up and took it for a ride. It was awful! The thing would not go straight especially under 25-30 mph. Then I realized I never loosened the big nut on top of the triple tree! DUH.
So I did the entire process again. Re-tightened. Retested. Unfortunately, my blood sugar was a bit low so I'm not sure how reliable my judgement was, but wow. It rode waaaaay better than ever. Still has a wobble, but handling-wise, it was awesome. A nasty storm was blowing in so I couldn't get my sugar up and go back out. But I will today.
I'll also jack it up and do the fall away test again today. I'm curious to see if it's any different. I also intend to tighten the head bearings a smidge.
I also have a new Commander II for the back coming in today! (I've put ~4k miles on a like new Dunlop and it's totally flat across already. Which could also be contributing to wobble.)
