I had contacted Keihin a year or so back in an attempt to get parts for the Interceptor carbs. The bad news is they said they could not help me with parts. The good news is that they told me that the Interceptor carbs are from a family of carbs that they still make and they offered me an alternate. Now the hard part, I have to dig through my paperwork and find the part number that they gave me. Hopefully I will be back with a follow-up posting shortly.
