OEM Keihin Single Carburetor Carb 23B ATF Unknown Application Look. I don't know what year or model this fits. Please do your research. This carb came with a bunch of others from a closed down motorcycle shop. It has been on the shelf for years. It is dirty so it will definitely need a rebuild or for parts. The piston is stuck. What you see is what you will receive, no more, no less.. You are buying this carb untested, as is, no returns. Please make sure it's what you need.
