1970 Honda CB175K4 · Fuel System Buying guide

Choose by the part of the fuel system you are repairing

Separate carburetor parts from tank hardware when planning the job. Package size matters for rebuild kits, while cap condition and available clearance guide the tank-side choices.

Parts to consider

Set the carburetor order by the job

Choose the linked rebuild kit for the number of carburetors being serviced. The kit application covers 1969–71 CB175K models, but previously replaced carburetors need their own identification. A float with pin is available through the related link and is sold individually; verify the parts you need before combining purchases.

Allow room for the replacement petcock

The linked petcock has stock-fit coverage for later CB175K models and a longer-than-original qualification for 1969–71. On a 1970 tank, compare the space around the valve and fuel-line connections. A changed tank also requires a check of its attachment rather than relying on the motorcycle year.

Common ordering questions

How many rebuild kits should I order?

Each kit rebuilds one carburetor. Count the carburetors being serviced and identify any replacements before ordering; the application range alone does not establish the contents needed for a modified setup.

Is the petcock the original length for 1970?

No. This replacement is longer than the original on CB175K models from 1969 through 1971. Check clearance and the fitted tank connection before choosing it for your motorcycle.

Does the chrome cap require a separate gasket purchase?

The complete chrome cap arrives with its gasket installed. A separate cap rubber is an alternative for a seal-only repair when the existing cap and its mating surfaces remain suitable.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
