Took my littel road trip 500 mile approx with my America 03 and a texas ranger sidecar. 70 to 80 MPH got 30 miles per gal. and on back roads at 50 to 60 MPH I got 35 miles per gal. I'm happie life is good,but. got over 3 turns on pilot jet I order a 45 pilot and a 132 main. I need just a littel more tork on take off. may need new clutch spring and a 43 rear spocket as well. That better mileage thasn my 07 harley got with the same sidecar. rudyr
