I have no idea . I was told the tension on the rings at rest would be enough to keep it (Compression)from bypassing the rings to the crankcase and that as the cylinder pressure increased the ring tension got higher . My intension was not max effort for sure . At this point I have no crack case evacuation , meaning I just run breathers with tennis bands around them. I really don't have room for a vacuum pump system without taking the inner fenders out . My machinist is a guy I went to high school with and is still in my home town. He went with me to my last race and really knows what im doing . I let him know that the main goal was to keep it simple . Load it , race it and put it up . I already work on it enough .
