Slow System - Suzuki GSF600Y 2000 Service Manual

SLOW SYSTEM

This system supplies fuel during engine operation when the throttle valve 1 is closed or slightly opened. The
fuel from the float chamber 2 is metered by the pilot jet 3 where it mixes with air coming in through the pilot
air jet 4. This mixture, rich with fuel, then goes up through the pilot passage to the pilot screw 5. Part of the
mixture is discharged into the main bore through bypass ports 6. The mixture is metered by the pilot screw
5 and sprayed into the main bore through the pilot outlet port 7.
