Primary noise 2012 SG 103
OK I found a video of another Harley which sounds pretty much like my new 2012 SG this noise started at about 250 miles after the mechanic rode it for another issue, and the noise hasn't changed any now that I have 600 miles on it.
This noise is mostly noticeable at idle but I can hear it sometimes going up in the gears.
Seems noisier warm that cold but is still there when cold.
Remember this is not my bike in the video but this is basically what it sounds like.
What do you guys think?
I have heard other 103's make this noise and some don't.

Try the Hayden M6 tensioner. Made a world of difference on my bike. My primary is dead quiet now.
That sounds like the chain is too tight, especially since it is louder when cold. The chain gets a little tighter as it cools down.

So, I remove the tensioner, clean it, re-install, and then adjust. This solves the problem for some time but it comes back.
As suggested above, I'll either replace the stock tensioner or, like I've done on other bikes, sharpen the teeth on the tensioner's ramps and see it that helps.
Personally, I think the stock tensioner has either too many dull teeth, a weak spring, or sloppy fit and that allows the ramp to unadjust.
Good luck!

I have always hated this noise on my '09.......put in a Hayden BTO7 6 weeks ago......noise gone. It's designed so the chain shoe "floats" in between the 2 guides and is isolated from transfering the noise through the primary. Dual springs ( no rachet effect) underneath the shoe alows for the tension to be niether too loose or too tight. Easier on the comp and primary bearing. Best $115 I've spent, 30 minute install. :-)

My 2012 makes a similar noise. I've removed the primary cover only to find the chain quite loose from the tensioner backing down.

The noise I am speaking of is the whining noise that goes up and down in frequency when throttle is applied and let off.
I am not speaking of the clatter noise.
To me the whining would be caused by a primary chain that is too tight, not to loose.

If you remove the clutch cover and look in the primary you can check to see if the chain is loose. There is a service bulletin from HD about running the motorcycle up and down thru the gear with enthusiasm to get the chain tensioner to ratchet up to the next stop.
There are apparently some hit and miss quality control issues with the tensioner and the compensator from about 2007 to present. Nothing like good ol american quality, money first, people and integrity second.

Damn,
that's quite the "whirring" sound, which if my bike were doing that, I'd be back at the stealer demanding they find it and resolve it, period.
And they would barring all the horror stories we hear of on here where the stealers say "that's normal"..........

What primary lube are you guys running? I had the same whine coming out of a 2010 RK that I had been running Syn3 since it was new and up to about 15,000 miles. Then I changed out to Formula+.
Also, before when I changed the primary lube in the past, I stood the bike upright and level, then poured into the derby cover until I could see the standing fluid through the cover. But, the service manual says the capacity is 45 fl oz (dry). So, this time when I changed out to Formula +, I put in 45 oz and when I looked into the derby cover, it looked like it was overfilled by about a half inch. I sealed it up anyway and fired it up. No more whine at all. Now almost 20,000 miles and still no whine and no leaks.
Just my 2 cents.
