Frequently Asked Questions

How many Honda 16139-300-004 needle-jet holders are included and required?

One carburetor needle-jet holder replacing Honda OEM 16139-300-004 is included. The compatible CB750K uses one per carburetor, so four are required to replace the holders in all four carburetors.

What should be checked before replacing a needle-jet holder?

Compare the original holder, needle jet and metering components with Honda OEM 16139-300-004, and keep all carburetor parts organized by position so mismatched worn components are not mixed.

What should be done after installing needle-jet holders?

Confirm every metering passage is clean, install the related jets and needles in the correct order, set float height and mixture adjustments to specification and synchronize the complete carburetor rack.
