Specifying only genuine OE bearings when rebuilding the engine unit will mean using the same items used by the factory. Why risk any other make of bearing with something as important as your motorcycle?

Have you ordered all the parts you need for the engine overhaul? Valves, valve springs, valve stem seals and of course gaskets.
