Lets build some powa! What is done with the engine build is determined buy the rules your competing under, level of maintenance you want to perform and of corse your budget. From stock, superstock, supersport, superbike and beyond. Combustion engines are an air pump so their ability to breath is everything. Milling the gasket surface allows us to tune the combustion chamber size and compression ratio. CNC valve job gives us a clean and consistent radius for optimal air flow past the valve seats. CNC porting forms IN/EX ports for optimal flow that is 100% repeatable from head to head. The unsung hero of a good breathing engine is properly evenly set up valve clearances.
