Re: would carbon knock be my problem ?

What kind of gas do you run? I didn't think gas could cause that much carbon but according to Matt's post #15 it can be caused by inferior gasoline. I know high test gas can carbon up motorcycles but didn't think it could be anything like this.

With your stock pistons about .025 in the hole with a .015 gasket would give you around .040 of quench. You probably do have .040 of carbon on some of those pistons. Very weird.
