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. With bolt on and run performance right out of the box with easy tuneability for a smooth throttle response throughout the power band. Available sizes from 650 up to 850 CFM to match your needs.
