Hi all- I've got a 1990 Standard. Just got it. First Goldwing. The carbs needed work. Got them out cleaned repaired and back in. Did some body panel repairs and cleaned it up underneath when all those fairings were off. Got it back together and it runs real sweet now. Only thing is the mileage is not what it could be. On the highway at about 65-70 mph it's getting about 31 MPG. I think/hope that it should get more like 40MPG or better. Any help or advice here. Thanks.
