Hello, after a top end rebuild on my 91 ultra. I can hear and feel air coming from the center opening on the head. Any idea what it could be? New 0.10 over CCI pistons were not marked fornt or rear....New head gaskets as well as base gaskets.

 

i NEED MORE INFO BUT I THINK MAYBE YOUR ROCKER BOX GASKET IS UPSIDE DOWN AND YOUR FEELING OR HEARING THE ENGINE VENTING THROUGH THE HOLE INSTEAD OF THE AIR CLEANER.ONE WAY TO CHECK IS PULL OF AIR CLEANER AND SEE IF AIR IS BLOWING OUT THE TWO VENTS ON THE HEAD IF NOT THE GASKET MIGHT BE IN WRONG.

 

thanks for the input...took the rocker covers back off and the center gasket had moved and came off. going to get another set tomorrow just in case..
