Effect on Gas Milage
This is an update from my review of last autumn. In addition to all that I posted there, I discovered on a recent 2000 mile trip that this shield has an effect on gas milage over the stock shield.
At 6'2" I have mine set at 16", just enough to hit the top of my helmet so I get the ventilation I desire through the helmet vent holes, but not the wind in my face when I have my face shield up.
At this setting I am discovering about a 15% increase in gas milage. This was a bonus I was not expecting! The first tank on my ride on Highway 40 through the Colorado Mountains and seeing 46 MPG made me think this was just a lucky day with some wind at my back. However, riding through Wyoming, Utah, Montana and back (through the Tetons and Yellowstone, in Wyoming wind, etc.) I was comparing my milage with similar conditions over 35K of riding with the old shield. 12-18% increase, depending upon conditions. On one tank I got over 50 MPG. And, this is including deducting 3% from the odometer reading to compensate for the 3% the odometer is off on my 2012 GL1800.
Second verification is that I can go about 250 miles on a tank before the warning light comes on compared to about 210 miles, depending on speed and wind.
