PLEASE NOTE I HAVE NO IDEA WHAT MOTORCYCLE THESE WERE DESIGNED FOR.
I really could'nt pass these up. Brand new CV carbs linked together.I have been told by a noted Honda expert that they were likely from a European CB125/175 twin. At any rate, if you have an application where you need some neat CB carbs, you wont do any better. The cylinder intake ports measure 26mm(ID) and are 31mm apart. The airbox side are 42 or 44mm(ID).
Left carburetor is the only one that is marked, the right has no marking.
The Left says "KF Standard of Japan" The number below is very slight and hard to read. It appears to be "EH25JS2"
