Primary Noise.....Inner Primary Bearing??
First, here is the noise I am hearing 1) When coasting to a stop when I pull in the clutch I get a noise from the primary that sounds like the famous 5th gear whine (best way to describe it), and 2) If I am stopped and put the bike in neutral I also hear it, with or without the clutch pulled in.
So is this an inner primary bearing? reason I ask is most people say it goes away if you pull the clutch in, not mine, if it is in gear with the clutch pulled in no noise, but as soon as I get it in neutral the noise starts up even with the clutch pulled in.
Sounds like it is coming directly from the primary cover.
Any ideas?

pardon the ignorance, but wouldn't the bearing stop making noise with the clutch lever pulled in?
oh...you already mentioned that...but yeah it seems like it would kill the sound.
Have you tried a mechanics stethoscope to try to isolate the sound?
Maybe open the inspection cover while the bike is running? Probably get some oil on ya, but it would help to pinpoint the location?
Could also be clutch hub bearing, no? That could keep making noise even with the plates disengaged.
Hell, could be a few things it seems...get a scope and see if you can narrow it down, or just pull the primary apart if you're sure. Take the outer cover off and take your time and inspect each component as you take it off. See if the clutch has play while it's still tight on the mainshaft, see if the primary chain is rubbing anything, check the compensator nut torque, inspect the primary chain tensioner, etc...once you've looked at every part in that layer you can maybe pull the compensator, chain, and clutch assembly and inspect the clutch bearing and then get into the stuff behind it.
It's a really easy job, even if you have to pull the inner primary and replace that bearing. Im sure you have a manual, so there ya go!

The All ***** version is significantly less cost wise than the Baker, also.

Bowhunter61, that's a very familiar sound and my guess would be inner primary bearing. Your dealer would be able to confirm, and there is some precedent for HD to fix it as a warranty repair even if you are outside your two years; they replaced mine twice outside of warranty. Seems to be a common "wear item" on the twin cams.

seems that letting Harley do it, replacing the apparently faulty part with another potentially faulty part makes no sense.
At the very least, try to convince them to install a better bearing? Every wrench I've talked to said stock primary bearing was good for the life of the bike usually, but we were talkin evos.
I'm new to TCs...is the inner primary bearing different than what was on my evo?

Are you sure noise 1 isn't just the straight cut gear in the trans? I only notice it with the clutch in coasting to a stop if I'm in 1st gear.
Noise 2 doesn't sound normal.
