Hi everyone, I am still having issues finding a restrictor for my vf400f, I have found a guy on ebay who makes restrictor kits and has well over 2000 positive feedback, he has told me if I can get him the dimensions of my carbs he will be able to make one for me. The only problem is I have no idea what they are. He assures me that a vfr400 nc30 restrictor will work fine. I contacted Honda and they said they will not even give me dimensions of the carbs as the part is not genuine Honda. Really hope someone can help, I have worked so hard to get my licence and have no intention of losing it over something like this.
