Thanks for the comments. I really loved how my SG looked, and I'm liking the new Ultra more and more. Orange really is the fastest color.
Well, I've been able to put a few hundred miles on the new 'sickle, and it's doing great.

I'm enjoying riding more now that I can relax, and not have to think about every new noise coming from the drivetrain. I am thinking more and more that my SG was a bad seed.
I am having an issue with the stereo. It cuts in and out as if there's a loose connection, but I'm not going to sweat it; that's a warranty issue, and doesn't affect the important stuff. It wouldn't be a Harley if nothing goes wrong, right?
New, the '12 popped, backfired, stalled, burned oil, and sounded like loose marbles were living in the motor. the motor sounded like a harmonious collection of mechanical noises. The howling from the primary
On my '12 SG, the oil would be sooty black after the first 10 mile ride.
With the backfiring, stalling etc sounds like it needed a tune.
What mods did you have done to the engine/exhaust?
Marble sound may have been engine knock/pinging! tune and fuel would have fixed this if it was the problem.
Black sooty oil.
How often between oil changes?
Howling in the primary.
Tensioner would have over ratcheted to cause the howling.
Sounds like you had a rotten egg there.
I must be one of the lucky one's, my 12SG runs great and oil looks like golden honey between oil changes.
Only mechanical issue I had was drive belt was a little tight.
Warranty issues is another story but only cosmetic to the total of approx 4500k
BTW, Very nice bike, that's got to be the best colour choice.
It being my first Harley, I was told it (the sooty oil) was normal by the dealership. I also was told that the bike using a quart of oil every 2000 miles was normal, even on a new bike. I probably changed the oils every 3000 miles. Noises? All normal with the 110, according to dealers. I installed an M6 primary chain tensioner in the '12, and the howling from the primary was much better. I haven't heard any of that howling on the '13 yet. In the '12, I replaced the compensator at 5000 miles.
The backfiring, stalling, and heat almost completely disappeared when I changed the pipe and put on a fuel controller (the Cobra PowrPro). The various motor noises never went away. I made a lot of mods to the '12: 2-1 pipes, TTS, RSD intake, 113 pistons and cylinders, 10.5 pistons, 30t sprocket, etc. Like I said, the '12 SG was running really strong when I traded it. There were still lots of ticking and primary noise, though. I was tired of the dealers telling me it was "normal".
