The other bulletin is the one where they tell folks the neutral rattle on a Cruise Drive trans is "normal". That's the rattle you can hear at idle with the bike in neutral and the clutch engaged, and it's caused by the play in the trans gears and bearings combined with the pulses from the engine. While Harley proclaims it to be normal to blow off complainers, it really isn't normal for a trans built to proper tolerances. Such is the way Harley does business. Cheapen the product, create problems that didn't previously exist, then call the result normal when customers complain. In this case the OP says the noise is heard even when riding. That is not what this bulletin is about, but it's not surprising to me to hear of a dealership employee blowing something off by quoting a bulletin that does not apply to the situation being discussed. It happens a lot.
I assume you rode this bike before this latest work was performed? Can I further assume that the noise you have now wasn't there before? If the answer is yes, then it's obvious your so-called mechanic screwed something up. I don't think I'd let him off the hook so easily (I noticed the other new thread where you are asking for a good tech in your area), but you have to do what you have to do. And btw, I've heard plenty of lazy folks claim they knew how much torque their impacts produced when they were called out when caught using one to install parts. Anyone who tries to blow that smoke up people's butts is either stupid, or thinks the guy they're blowing the smoke up is stupid. There is a huge difference between locking the shaft in place and applying smooth and even force to a nut, and just hammering away with an impact. It's not just about the final torque achieved.
Good luck.
