Designed for applications going beyond the average mild street performance and into the realm of more serious power. These double pumper carburettors with mechanical secondaries and two instead of one accelerator pump become a more effective solution. These carburettors are manufactured from lightweight diecast aluminium components. They offer all the tunability and options that you would find from more expensive carburettors in the market today. From having a beautiful appearance, four-corner idle adjustment and screw in air bleeds. All models have dual inlet fuel bowls with sight glass windows for safe and easy float adjustments. Screw-in air bleeds and idle feed restrictions for tuning capability. With bolt on and run performance right out of the box with easy tuneability for a smooth throttle response throughout the power band.
