The new RNP Bullseye for KTM, Honda & Yamaha is the final word in airflow improvement for your carburetor.

The reason that it works so much better than any other splitting device is simple. Air velocity increases when running along a surface. The carburetor only has two surfaces, the opposite sides of the bore and in the middle of the bore velocity is at its lowest. Other carburetor air splitting devices currently available offer four surfaces. Each side of the bore and each side of the wing. The Bullseye provides twelve surfaces. Each chamber has three surfaces, times four chambers. The velocity is three times greater than that of competing devices.

Not only does it reduce the incoming air turbulence, but the velocity is increased at all throttle openings. The results of the Bullseye are more power everywhere, bottom to top, not just on the bottom like other carburetor splitting devices.

There is increased throttle response at all throttle openings and less chance of stalling in tight, low rpm situations. The increased velocity requires leaner jetting that improves fuel mileage.
