Unlike other kits that require machining, this Power Pack includes a purpose-built 63mm cylinder paired with a matching long-case "B-case" crankcase with oversized 57mm stud spacing � no case machining required. The cases arrive with all oil seals pre-installed and are drilled and tapped for an optional oil cooler.
