1971 Honda CB350K3 · Fuel System Buying guide

Check the installed carburetors and tank first

Fuel-system work can involve sealing, fuel delivery or carburetor internals. Identify the problem and existing hardware before choosing a rebuild kit, an intake holder or a fuel tap for the tank.

Parts to consider

1970-73 Honda CB350K / CL350K Carb Rebuild Kit Round-Bowl Carburetor Rebuild KitRebuilds one round-bowl carburetor; confirm the installed bowl shape before ordering.View part Honda CB Carb Holder with Gasket ~ Replaces 16211-286-040 Carburetor Holder with GasketOne holder and one gasket, with a stated 1970–72 CB350K application.View part Honda CB Fuel Petcock ~ Replaces 16950-292-000 M16 × 1.5 Fuel PetcockReplacement fuel tap with M16 × 1.5 mm threads; check the installed tank connection.View part

Plan the carburetor job as a pair

The round-bowl rebuild kit services one carburetor, so a two-carburetor rebuild needs two compatible kits. The holder package also contains only one holder and one gasket. Inspect both sides, but avoid replacing sound components merely because another part is supplied singly.

Let the installed hardware guide the order

A changed fuel tank can alter the petcock fitting, while exchanged carburetors can alter bowl shape and internal parts. Record those details before ordering. If custom pod filters or exhaust changes are involved, treat jet selection as a tuning decision rather than a model-year shortcut.

Buying questions

How many rebuild kits do I need for both carburetors?

The featured kit services one round-bowl carburetor. Order two for both only after checking the installed bowl shape and carburetor application; a previous owner may have changed the carburetors.

Will the petcock fit any tank on a CB350?

Check the actual tank connection for M16 × 1.5 mm threads and compare the outlet arrangement and clearance. An aftermarket or exchanged tank can need a different tap despite being mounted on a CB350.

Should I choose jets solely from the year tag?

No. Identify the carburetor, jet type and existing stamped size, then account for any intake or exhaust changes. A model application does not make every available jet size the correct setting for your motorcycle.

Not sure which part you need?

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