The latest from BBK After talking with BBK yesterday I have learned that there is a major problem with the Viper Throttle body. It's not just me. They are going to replace several of these in the next few weeks since the problem seems to be in the mfg. Last night as I was removing the BBK from my viper I put it up to the light and could see how poorly the butterflies fit. Some areas were rubbing angains the body. one side was much worse than the other. I then compared it to the x-Metal and the butterfly had perfect clearance all alrond the body. Big difference here. I do hope to get a BBK that is correct soon.
