Do oversize pistons give more power?

The short answer is that a bigger bore is generally the best way to get more power. It creates more space, allowing for bigger valve openings, which in turn can bring more fuel and air into the cylinder. A bigger bore with a shorter stroke also allows an engine to rev higher, which creates more horsepower.

This second process to cylinder honing can be done with the same tool using finer grit stones, or a flex hone tool. Either medium (220 grit) or fine (320 grit) stones are used for finish-honing.

Does more displacement mean more power?

Generally speaking, the higher an engine’s displacement the more power it can create, while the lower the displacement the less fuel it can consume. This is because displacement has a direct impact on how much fuel must be drawn into a cylinder to create power and maintain engine operation.
