Keihin 20mm Twin Carburetors for parts sku 6569

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. Nbut you can ask questions about condition before purchase from a 1960's twin, see the crossover for the chokes. Ignore the picture that says 18mm, their intakes measure 20mm. They need tops, slides and jets,  but inside looks NOS clean,
