The way I see it is this.
Your bike most likely had the HD360 oil from the factory which as far as oils go is pretty good oil, only the CVO bikes get to use that poor excuse for an oil SYN 3.
You NOW have Syn 3 in there so I would drain the engine oil and replace it with a quality oil like Mobil 1 synthetic, it may be the difference you are feeling here.
SELECT......Don't settle on oils.
