Once you acquire your GSR750 service manual, do not read it cover to cover. Sticky-note these five sections:
Unlike old carbureted bikes, your GSR750 uses a ride-by-wire secondary throttle valve. If you take the throttle bodies off without the manual, you will misalign the secondary valve position sensor (SGPS). The manual shows you exactly how to use the "Mode Select" button on the dash to read the sensor voltages and set them to 0.98V ± 0.02V. YouTube won't show you that. gsr750 service manual
