I FORCED myself to keep the speed at or under 65 today and the MPG went back above 60mpg. Two tanks this week with mostly highway driving but no baggage to speak of were under 58 MPG. Steering has a wobble when I take my hands off the bars at speeds below 30. Brought tire pressure up to 38 front and 44 back. No change. Maybe lift the bars one inch to see if that is causing it.
