Frequently Asked Questions

How many Honda jet-needle sets 16012-323-004 are included?

One jet-needle set replacing Honda OEM 16012-323-004 is included for one carburetor. A 1971-1976 CB500K or CB550K uses four carburetors, so four matching sets are needed when servicing every carburetor.

Why must jet needle 16012-323-004 be matched to the carburetor?

Needle taper, clip arrangement and companion needle jet affect fuel delivery through the midrange. Confirm the carburetor identification, Honda part number and original needle code rather than choosing by motorcycle appearance alone.

Should all four carburetors receive the same needle setup?

Use the Honda specification for the exact model and carburetor set, install clips or spacers in the specified positions and synchronize the carburetors after assembly. Do not use needle position to hide blocked jets, air leaks or incorrect float height.
