Is it me or does the 14 idle a bit erratic and noisy as compared to the 2012 103 motors?

Anyone else have noticed this?

 

My '15 is as smooth at idle as any other Harley I've owned.

Is it the engine temp manager cutting the rear cylinder off at idle? I've kept that feature turned off on mine to avoid the rough idle and noises that you describe.

 

My 14 is the smoothest I ever had to.

 

No, I am quite familiar with that. It is a rough idle but not in a sense of missing or else. It is hard to describe. I guess I will go down 5 miles to the HD dealership here to let them take a look.

 

When mine was stock it had kind of lope at idle.I liked the way it sounded.When I got an FP3,slip-ons and A/C ,the lope is gone.

 

Mine does...

 

I don't have a 2012 103 to compare but the new 103 had a different cam, air cleaner and probably different exhaust.
OR, maybe your bike is acting funny so the dealer can fix all that.

 

Took it to the dealership and yes, it is normal and it is a product of the new cam and the other things they did to fight the heat. It does idle a bit rougher than my 12 103 engine but the 12 103 engine is considerably hotter. So mystery solved and I am a happy camper again.

 

I had the same unsettling issue/question when I first bought my bike almost 2 years ago. Best way I can say it, was a "stumble" in the idle and unsettling noise.

Dealer said it was normal.

However for me it is due to the heat management system turning off the rear cylinder plus the lean run condition in closed loop mode.

I did do a few simple mods, added XIEDs and decatted.
I also disabled the Heat Management System. Your owners manual says its for rider comfort, I didnt find it comforting!
In your owners manual are instructions on how to turn it off.
Takes only seconds by rolling the throttle forward. You can turn it off and on at anytime or just leave it off, as I do now.

 

Change your primary to Formula+. Thought same as you until I did that.
