I had come to the conclusion the chamber is larger than the bore.

the way I see it, it is not good for flow or efficiency so I am tempted to go overbore.

This could also improve torque to capacity ratio with smaller ports capacity wise => lower peak torque rpm.
Obviously, more capacity equals more fuel and I am already geared not as low as I would have liked so I can't see how to offset the increase in capacity ...

That being said, it would also raise CR very easily.

Thoughts ?
