zekibanshee Posted February 25, 2011 Report Posted February 25, 2011 Okay here it goes if how do tell when your ports are open with a degree wheel this is what I came up with. When the piston starts to uncover the exhaust port I get 188 duration or when I do it the other way when I don't see light trough the port it gives me 190 duration which one is the correct way. O by the way top of piston crown transfer are 120 duration is those duration a all around port Quote
