Sorry, more info would have been good.
The bike is brand new, got it from the dealer with 1 mile on it. I drove it to work and noticed the movement on the 202 east highway, there was a lot of traffic since it's Phoenix area. When I got to work I checked tire pressure, it was 31/36, but I'm a big guy so I put them both at 42 before I left at the end of the shift, just to see. I then took the 101 north into Scottsdale and it didn't shift around as much, but it was still doing it. On the way home I took surface streets, so nothing there. It's not a continuous movement, like an oscillation, it's just a little shift then it stops, then shift again, all random. As for wind, we usually have a breeze here but it's not terribly fast.
On saturday, a co-worker that rides regularly will take it out and make a comparison. I could just be overthinking it
