So I had to replace my Oil pump as it started to go south.. BTW it is 2002 FLHTCUI with 65K on it. So I replaced it with the SE High output.. I replaced the Push rods with Crusher adjustable quick install ones.. Put back together and the bike runs good but the front cylinder rockers sound like I am hammering a nail.. I rechecked the push rod adjustment per the specs and still there. What next? Do I need to pull the covers? if so what is the best alignment for the rockers?
