Hi All,
I have a 2014 Limited, and drove a 15 limited, and they idle rough.
the Bike wants to buck and surge at slow speeds, such as stuck in a traffic jam, or a school zone.
It must be the higher compression and cam in the water cooled motor?
I had a Dealer try to tune it out, and he said it is a mechanical issue that he can't fix with tuning.

HELP? any ideas?
thx

Get a good (non-MOCO) tune.

I've installed larger after market cams with proper tunes in 96"/103"/107" TC's that were smooth as baby's butts down low in parking lots/traffic.
The cam in the 14-15's is not really that much cam. Certainly not enough to cause that.

As mentioned above they're tuned SO LEAN from factory that the first thing to do is put a real tune in it.
