Honda Small displacement Carburetor Manifold sku 5730
Not sure which model this fits, but it would be a smaller displacement Honda. It came from a Kehin carb that had no markings on it. The opening on both ends of this piece measures 22mm The Air intake side of the carburetor it came from measured 28mm.
It has been suggested to me that it is from a Keihn Super 90 Honda, but no guarantees on that model fitment. You can also see the total length.u is 90mm. Please make sure that it is the part you want, no return of parts.
