I recently installed 2.5 inch fullsack cores in my 2016 CVO FLHXSE with the stock head pipe.
When riding the bike in traffic it seems the " Harley safety" where it stops firing the rear cylinder because of heat starts taking effect a lot sooner than it did before . Is this just me ? Or has anyone else had this experience?

Did you tune the bike with any type of aftermarket tuner or did you just install the new baffles? If you didn't tune the bike - and even if you did - it may be running to lean with the exhaust change.  I know it's been said that the ECM can adjust for muffler/slip-on changes, but IMHO too much of a change in the airflow and backpressure characteristics will confuse the ECM and it will be unable to adjust for the change.

Just my $.02, I'm sure other with more knowledge will chime in.

you have a 2016.  when the rushmore bikes came out in 2014, they changed the parameters for eitms activation.  it is no longer related to cylinder head temp, but one of the triggers is now outside ambient temperature >80*.

I guess they figure that if it kicks in early, before the engine gets really hot, that it'll run cooler longer?

i turned that etms off on my 16, its a pita the way its setup now

The EITMS is set up differently on the Twin Cooled bikes, so that it's triggered strictly by ambient air temperature and not cylinder head temperature.  I assume that change was made because they expect the water cooling to keep the head temps controlled in a much narrower range and the system wouldn't kick in as often.  Don't forget that Harley has always claimed EITMS is all about rider comfort, and shutting down the rear cylinder does pump air through the head and exhaust which will reduce the heat felt by the rider.  I would suggest if the rear cylinder shutdown bothers you, and if you don't have an issue with the heat coming off the rear cylinder and exhaust when stopped, then you should disable EITMS altogether.  It's a simple and easily reversible process, so go to the owners manual and follow the directions to turn it off.  If you like it that way, fine.  If you don't, then just repeat the steps and turn it back on.
