My 1995 Gsx started making this awful sound after pushing 18psi on my brand new hx40. It gets worse the louder it revs and the knocking is accompanied by a terrible screeching sound from the valve cover it sounds like. I have a data log and video to go with it. I have no idea what this sound is , please help....
