For the mechanically minded, this was so interesting, thanks for posting Karl.. Stripping and rebuilding a GM engine - 10hrs labour . Every 60 races . No wonder speedway is so expensive. If the titanium valves are pitted - throw them away ! And who would have thought the valve spring pressure could make such a noticeable a difference to the engine power characteristics . All so high tech. https://facebook/l.php?u=https%3A%2F%2Fyoutube%2Fwatch%3Fv%3DNqqXRU_Ljkg%26list%3DUUWMqEj3-1TXYlaGQppBGtbg&h=nAQEQ_pPE
