About the Honda CB100K

Detailed CB100K fuel and sealing repairs, with a separate 1973 front-brake application.

Honda Motorcycle Logo

For a 1970–1972 CB100K fuel repair, separate the tank tap from the carburetor’s float valve. The petcock controls fuel leaving the tank; the needle and seat regulate fuel entering the bowl. Compare the carburetor kit’s contents before adding a separately sold needle-and-seat assembly.

Locate the oil leak before choosing gaskets or shaft seals

The engine gasket set and oil-seal kit both list CB100K 1970–1972, but their contents address different sealing locations. Identify the leaking joint or seal and compare the pieces needed for access and reassembly. The front shoes extend to 1973; that brake coverage does not extend the featured fuel or engine parts.

Know your model before choosing partsCB100K repair checkpoints

Do not add both automatically. Kit 48-1387 and needle-and-seat assembly 48-5009 list CB100K 1970–1972, but the kit description does not identify the exact float-valve assembly supplied. Confirm that contents comparison with PartsNMore first. Add the separate assembly only when needed and not already included.

The year ranges below belong to the individual products. Keep your selected year in the comparison when opening a repair link.

Fuel tap

Check the tank-side component

A carb kit does not repair a leaking tank tap. Match the petcock mounting, outlet direction and fuel-line connection.

Carburetor

Compare kit contents with the float valve

The needle and seat control fuel entry into the bowl. Add them separately only when the repair requires them and the selected kit does not supply them.

Engine sealing

Identify the joint or seal location

A gasket set and an oil-seal kit are different products. Use the component location to choose the appropriate parts.

Identify your motorcycle before orderingCB100K identification checklist

Keep the frame marking, engine number, CB100K model year and carburetor identification together. Record changed assemblies and photograph the old part before dismantling it. Match a replacement front wheel and drum to their own component details.

  • Keep the complete model designation and year with your parts list.
  • Record frame and engine markings separately. A replacement engine needs its own parts comparison.
  • Compare the component fitted to the motorcycle, the product application and the package contents.

Restoring or customizing your CB100K?

On a CB100K with changed controls, check bar diameter, cable reach, mirror threads and tank clearance. Universal accessories need measurements from the assembled motorcycle.

Universal parts may require modification and are not a confirmed CB100K fit.

Honda CB100K parts questions

Which Honda CB100K repair parts cover 1970–1972?
The featured carburetor kit, separate needle-and-seat assembly, fuel petcock, engine gasket set and oil-seal kit list CB100K 1970–1972. Check the supplied pieces against the work planned so you do not duplicate parts already included in a kit.
Should I buy a separate CB100K float needle and seat with the carb kit?
Do not add both automatically. Kit 48-1387 and needle-and-seat assembly 48-5009 list CB100K 1970–1972, but the kit description does not identify the exact float-valve assembly supplied. Confirm that contents comparison with PartsNMore first. Add the separate assembly only when needed and not already included.
Does my CB100K oil leak need an engine gasket set or an oil-seal kit?
Locate the leak first. Gaskets seal mating engine joints, while oil seals retain oil at specified shaft or housing locations. Both linked products list CB100K 1970–1972, but their contents serve different repairs. Compare the actual joint or seal location before ordering.
Are front brake shoes listed for a 1973 CB100K?
Yes. The linked front shoes list CB100K 1970–1973. Confirm the fitted front drum and shoe dimensions. That 1973 brake application does not extend the featured 1970–1972 fuel-system or engine-sealing products to 1973.
