1978 Honda CB750F · Carb rebuild & jetting Buying guide

Choosing carburetor rebuild parts

Choose the repair contents before choosing a kit. The full rebuild kit adds metering parts to the gasket-and-needle selection in the packing kit, while individual gaskets and the float needle support smaller repairs.

Comparing kit contents

Full kit 48-1737 supplies bowl/top gaskets, a D313 slide needle, needle jet, float needle, main jets, air-screw parts, E-clip, washer and six O-rings. Packing kit 48-1995 supplies bowl/top gaskets, O-rings and a needle. Each kit is listed as servicing one carburetor; order the quantity needed for the planned work.

Separate jet purchases

Assortment 48-2111 contains four each of #105, #110, #115 and #120 main jets. Pilot pack 48-9028 contains four #35 press-in jets and asks buyers to verify the size required. These choices supply parts for an established setup; they do not prescribe jetting for a changed intake or exhaust.

Rebuild questions

Why does the full rebuild kit include #105 and #110 main jets?

The kit assigns #105 to the 1977–78 F and #110 to the 1978 K. Those are the supplied parts’ application notes; use the component suited to the carburetor and setup actually fitted.

Which supplied air-fuel screw is intended for the 1978 F?

Kit 48-1737 supplies one screw described as the 1978 F type and another as the 1977–78 K type. Match the F-type component to the carburetor fitted; the alternative screw is supplied for a different application covered by the kit.

Does reference 16010-405-004 mean a packing kit or just a top gasket?

Both products use that reference here. Choose 48-1995 for the packing kit with bowl/top gaskets, O-rings and needle; choose 73-0953 for the individual carb top gasket. Use the product number and contents to distinguish the order.
