My first question is specifically on port timing. When someone ports for a 4mill stroker, do they bring the durations back to stock or do they go past for different types of power? The second question is on port selection, being as I am a little bigger rider(AKA fat) I am imagining I should go with a woods/mx port? Mainly riding on fireroads and farting around I would think a little broader powerband would help me extremely. Thanks for the imput ahead of time, I'm gonna go order my crank now...
