I have a compression tester on it's way. the 04-05 manual says the stock piston should have a compression of 108 psi. I have a 11:5:1 piston in right now. how much higher should the compression be? the cylinder has less than 20 hrs. an the piston has less than 10, But i believe it is fully broken in. Any help is appriciated!
