Frequently Asked Questions

How many Honda CB750 main nozzles are included?

Four main nozzles replacing Honda OEM 16166-425-671 are included, providing one for each carburetor on the listed four-cylinder CB750 models.

Is a main nozzle the same part as the removable main jet?

No. The main nozzle is a separate metering component in the carburetor's main circuit. Match OEM 16166-425-671 and the original nozzle body rather than substituting a main jet with a similar-looking orifice.

What should be checked before installing the four main nozzles?

Verify carburetor identification and compare nozzle length, side-hole pattern and seating depth with the originals. Clean the carburetor passages without drilling calibrated openings and install each nozzle squarely.
