I complained about the noise at the 1K service and I was told it was a normal sound, well it sure is if the primary is not aligned. Now I guess they will need to repair a much larger problem.

I would not be happy either.  I assume you have noted other entries here or on other forums for HD that mention the potential (side loading) of the primary chain due to the newest design of the compensator as compared the (older) style.  Might not be what caused your problem,  but it could be related.

Sad part is, I took it to a Independent shop to find out what the noise was.

Ouch!

curious what kind of a noise it makes?

thanks   Happy

Is there any required maint to the primary other than changing the oil at the 1K service?

No.  There is no inspection cover any more, since H-D went to the auto tensioner, so you can't even inspect it without removing the outer primary cover.  The only maintenance is fluid changes.

I knew there was no cover, so I figured there was no maint.....just making sure I wasn't missing anything

A very bad one, like marbles getting crushed.

Again,  not necessarily what your problem cause was.......but the newer primary chain tensioner is "suspect" too.

As I understand it,  it does (not) free-float with it's applied tension on the chain as ......spring loaded and other tensioners might.  It has a "ratchet" set of teeth that catches the tensioner at its tightest point.

So,  as a result, a condition could be that as the engine and all its parts warm/heat up,  the chain gets longer and the tensioner takes up "all" that slack via the ratchet teeth........then when its cold again,  that damn chain is tighter than a bow string.

I was just talked out of upgrading two older bikes to the auto  tensioner because my contact at the dealer said they are seeing these chains too tight as a result of getting on it and the chain tightens up on the slack side.
Sounds plausible, we need Myth Busters.

If you want an auto tensioner without the H-D version issues, go with the old original standby, Hayden M6.  No ratchet, strictly spring loaded.  Or even go with the hydraulic version if you can still find them, looks just like the Hayden but with a self contained hydraulic pump that uses the primary oil to take up the slack like a valve lifter.

The HD auto tensioner has a slight bit of give and take. As the chain get loose (to much take) the tensioner will "ratchet" up to the next tooth to take up slack. The problem is that it can "ratchet" up too much causing the chain to be too tight. Too tight of a chain can cause bearing failure in the clutch hub and main shaft bearing and difficulty shifting.

Loading and unloading the drive train in the manner above is NOT a good idea unless you want to shift your flywheels.

The 07+ primaries unfortunaltly cannot use the Hayden M6 or the still availible HB125 hydro tensioner as they do not have the mounting bosses inside the inner primary for them.

When you hear of a fix for this let us know. The new SE comp assembly made the bike seem about 5mph higher geared. I'm confused but thinking maybe the 49t gear behind the clutch but kind of spendy from EVO Ind.

I hear complaints all the time about primary noise on the 07 & up models. In my opinion the chain does run to tight.
