Purchased from an old line Honda dealer who stocked lots of OEM and high quality replacement parts in the heyday of Japanese imports but is now closed. NOS Items may have shelf wear, metal items may have slight corrosion, but pictures taken from all angles and you can ask questions about condition before purchase
These are amazingly clean. Not sure if they ever had any gas in them.
This set would normally have 4 carburetors, one carburetor is missing. On the other three, they have no float bowls or jets. One carb is missing missing its slide/ spring and choke plate. The other two carbs CV slides move easily.
Marked 42A P0LA this chart shows that these carbs are for 1979-1981 CB750K, as well as 1979-1981 CB750 C models
