PM Kuhlka. He's the man when it comes to block-off plates.Hooligan said:Thanks for the reply. I'm not looking for any performance gain, I just don't like the popping and the extra heat it causes. I'm trying to find some block-off plates, but it I can't find any so I'll just plug the reed valve covers with something and pull the rest of the stuff off. I'm sure TuneBoy has the proper tune; I have not visited the web site in a while. Thanks again!
