I still think a lot is wind. We drove back from Durango to Tulsa at Avg 80 on I-40, lots of trucks. I found if I leaned forward and tried to get even with the windshield (oxy-moron) that I could smooth out the turbulance. It worked pretty good. Something you can experiment with, but I still feel like it should be better when going into turns and it gets a little grisley at 85 and 90 without trucks. I see no harm in adding the stra8 fitment if I can reduce the wobble. I kept checking my tire pressures since I had to plug a flat early in the trip.
With the rubber mounts, etc., it makes sense that the alignment will change at different torque levels. I didn't think anything about it till I read this forum. You guys are spending my money for me faster than I can ride.
