EITMS disabled. Will it hurt the engine ?
I've started to dislike this feature. Where I'm in eastern WA its always 90+ days in summer. I like the idea of one cylinder shutting off to cool down the engine. But I really don't like it in real world experience. It just feels off. When I'm ready to go from stop and I gas it, feels like motor hesitates for a sec. I have read somewhere here someone commenting that it does not do that on M8 bikes. But anyways I'm not liking this feature and would like to disable it. Will it hurt my engine ?

Personally not a fan of HD's implementation but, it's there for a reason (they do not add build cost unless there is a return in warranty claims).
Put some money into good heat management (tune, fans, good oil cooler) and it won't kick on.

not entirely true. there are several parameters that have to be met for the eitms to kick on. they've changed those parameters in the past few years. one of them now is outside ambient air temp > 80°.

I’ve always had mine off. If it would hurt the engine to turn it off there wouldn’t be an option to do so. It’s for comfort. With a proper tune and no cat I don’t need it.

HD went to the expense of incorporating it for a reason (regardless of the parameters or whatever).. If you don't like their approach to heat management, it would seem prudent to have some other approach before totally disabling theirs. However, it's up to each owner to do what they with their bike.

When you get stopped at that one stop light in Omak........
I have had it disabled since my bike was new in April, in Vegas, where it's pretty hot most of the summer. It's not an issue, and won't hurt anything. I believe if you look in your owners manual, it expressly states it's a rider comfort feature.

I agree there are parameters for it to kick in. Not sure what part of my post you believe is not true.

this part: 'put some good money into heat management and it won't kick on'
unless you can somehow make the ambient air temp less than 80°, then it's gonna kick on. i do agree that it is a good idea to have some kind of approach to heat management though, if not for the bike, definitely for the rider.
