New stock size SBT Powervalve, retaining screw, and SBT leverlink. In the original design, the pin could work itself free, allowing the valve to drop into the exhaust port. The SBT leverlink surrounds the pin, preventing it from escaping — a much needed upgrade to the original design. (Additional purchase of the 46-406 seal and gaskets is necessary).
