That's 31mpg(imperial not American)
If I can't get it to do 40+mpg then they will be going. Good thing is they don't pee petrol all over my feet from the float valves
Great looking bike. Personaly and FWIW I wouldnt attempt a carb swap with out the aid of an air/fuel gauge. Lots of guys have put FCR-MX flatslides (the standard latest generation 250cc + 450cc MX 4 stroke...) on the DR650 and were getting brutal mileage except the bike was running good. With proper jetting via A/F guage mileage increased dramaticaly and the bikes run even better. I have the NGK AFX Powerdex A/F guage. $300 including extra extended SS sensor bungs shipped across a continent. Just sayin'
