The mbx6 has a small tank. Take out the fuel tank spacer and use the large filter. I needed to do that to get the car to hold 125cc of gas. I thought at first my new engine had bad mileage but it wasn't the engine it was the quantity of fuel in the car. Also once you get the speed to around 1.5-2 gallons is where it really opens up and gets awesome power and efficiency.
PS If you use a 6mm restrictor in that car you will still see all the top end in the world but your mileage will go up greatly as well.
