2000 Duece, tapping noise coming from the engine. Took the lifters out, they looked and felt fine. took off the rocker covers. Found that I could move one of the rocker shafts back and forth with my fingers. Seemed to be too much side to side movement of two of the rocker arms, although they were within Harley tolerances. One of the rocker arm bushings was worn to where I could move the shaft up and down slightly. So. I replaced the rocker bases with deltron bases, put in S&S roller rockers and new rocker arm shafts, noise still there. Went ahead and replaced the lifters with feuling lifters and installed new screamin eagle adjustable pushrods. Noise still there. I'm obviously barking up the wrong tree. When riding the bike, the noise is more noticeable on decelerating. If accelerating hard, the noise is not noticeable, although the bike is fairly loud. My question is what would cause a loud noise upon deceleration and light throttle but not on hard throttle. Any thoughts would be appreciated.
