Main system
The FLATCR carburetor has a pri-
mary main jet. This type of main jet is
perfect for racing motorcycles since it
supplies an even flow of fuel, even at
full load. Use the main jet and the jet
needle to set the carburetor.
Pilot system
The FLATCR carburetor is manufac-
tured with a pilot screw. The pilot
screw adjustment ranges from fully
closed throttle to 1/4 open throttle.
