logical: I have experienced the noise that you described. It is as if it only happens at certain RPMs. I previously rode a 99 FXDL w/ 95" SE Stage II Kit, 258 cams, SE heads / high compression pistons, air filter, & slip ons, Mikuni HSR42 for 29000 miles before trading it in on a 01 FLHPI. Had the new mill done up w/ 95" cylinders,211 cams, SE Stage II kit. Got 3700 miles on it since July 13. Noise is still there. It does not appear to be getting worse, but it isn't getting any better either! I took the time to break it in right,too.
I do not recall hearing this noise from the old motor. Did the factory make any changes that could be causing the noise? Gotta wonder.
P.S. Same wrench did both motors, I trust him.
