Have to ask, what is the deal on rear cylinder cut-out effecting compensator?

My theory (and yes only a theory) is when EITMS is active it is the equivalent of you trying to pedal a bicycle with only one foot on a pedal. I think that puts a tremendous strain on the crankshaft and the compensator.

Compensator is used as a shock absorber between drive train and clutch.  If bike is not in gear is not under a load.  When rear cylinder is shut down, it's function is basically that of an air pump.  Not aware of any excess stress on crank or compensator due to rear cylinder shut down.

Right, and the cylinder is not really shutdown, just the injection is stopped and so as you say it's just pumping air so mechanically with regards to the drive train it's the same as during ignition.

I'm having a FuelPak installed next week and wonder if that disables it. I had turned mine off on the 2014 Limited but then again, I had a FuelPak on that too. 

I do notice the cooling fans run frequently on the 2017 CVO, whereas the 2014 Limited's fans rarely ran. I'm thinking they lowered the temp activation. Anyone else notice that?

In 2015 they changed the threshold so the fans will come on at an outside air (ambient air) temp of 80 degrees, regardless of engine temp.

Thanks!  Good to know.  I guess the real issue is oil temp and I don't have a temp guage yet.

Am currently in Blueridge Georgia riding the curves on vacation. Friend of mine is with me on his M8 107 EITMS enabled. My 2015 110 disabled for the first time this week because it sounded like it was coming apart each time it kicked on at the beginning of our trip.

I notice that when we stop and shut down, his fans will always be running. Mine will either run for half the time or not at all. Don't plan on turing mine back on.

I have a fuel pak. . I do use the the feature because it's so hot here. . It works fine.  You shouldn't have problems problems due to that. . Stuart
