Richard - I have heard of offset boring to increase torque but don't quite understand how that works or why. I understand slight offsets can change the firing sequence so you can have more firing overlap on the crank. Is that it? I guess I am sorta asking for a short explanation on this because some racing sanctioning bodies have outlawed it. As for sleeves, all sleeves are not created equal, some can be bored out more. Thats all I am going to say about that.
