Case Boring

Revolution Performance offers in-house case boring service for 1996-present Harley Davidson v-twin engines. Our monster big bore kits are considerably large bore sizes than OEM or our bolt-on big bore kit line. Thus we have to modify the cases to accept the larger bore cylinders. We split the cases and set them up in a vertical mill and machine them to the exact specifications of our monster big bore kit.

Case boring services starting at $319.95.
