How to stop your Harley engine overheating in traffic What is Harley EITMS

How to stop your Harley engine overheating in traffic - What is Harley EITMS - Here I discuss the Harley engine and how it can overheat in hotter temperatures whilst in stationary traffic. I also talk about how Harley have a solution to assist the cooling of the engine and it is through the Engine Idle Temperature Management System - EITMS
The following is the basic criteria for it to automatically shut down or re engage if EITMS is enabled:
EITMS will activate (rear cylinder will turn off) when all of the following condition are met:
Engine temperature is greater than 287°F domestic 165°C international
Twist grip opening is at idle
Vehicle speed under 1 mph 2 km/h Engine speed under 1200 RPM
EITMS will disable (rear cylinder will again fire) if any one of the following occurs:
Engine temperature falls below 275°F domestic 135°C international
Twist grip opening is greater than idle
Vehicle speed exceeds 2 mph 3 km/h Engine speed exceeds 1350 RPM
Clutch is released with vehicle in gear
The ambient temperature is generally considered needs to be 80degF for it to activate.
To enable it, you roll the throttle into the off position and hold it there for a few seconds and wait for the cruise indicator lamp to flash green...to enable or flash orange...to disable.

One of my ironheads is a late 84. Last of the iron sporties. I put a fan in front of my oil cooler with a small shroud. Has a switch to turn on and off. Works great . Or I just shut the motor off until traffic moves. My other bikes I just shut it off. Lots of fun with a kick only chopper but I havent overheated my bikes

[@RevelatorAlf]

Cheers

[@FrensTimmerpens]

Mine is always on, and works even when it is not very hot outside. When its cold you can leave it enabled because the cilinder disabling doesn’t work, the engine does not overheat though.. so this option is best when enabled…and forget👍🏼

[@RevelatorAlf]

Yep cheers

[@priscillabordeaux1828]

That's great info. I have worried about my bike in the hotter than hell Oklahoma summers and riding in a city with over 1 million residents. I will activate my Sport Glide ASAP.

[@fatratz2012]

EITMS is purely for rider comfort. When it activates and“shuts off”the rear cylinder, it’s not because the motor is overheating. It’s designed to reduce the heat radiating from the rear cylinder to the rider.

[@RevelatorAlf]

Yes indeed

[@goldilocks913]

My scrotum salutes them!

[@HennieBours]

Exactly. Nothing to do with overheating the second cylinder.

Hi Which O2 sensor should I buy for my FXSB Breakout 2014 Denniskirk is claiming theirs better from oem as they are made with ceramic body made of stabilised zirconian dioxide, surface coated with gasspermeable platinum electrodes & porous ceramic help erosion due to contamination particles in exhausts

[@tonyj8947]

Excellent video Alf! As usual very informative and helpful to me. I have a 2020 heritage classic and had no idea about the EITMS feature. I'm thinking the oil cool system will keep it from overheating. Why would this feature ever be disabled? IMO just keep it on, its a safety feature. These bikes are expensive and, to me, there is no reason for the bike to overheat regardless of how long the rider is idling.

[@RevelatorAlf]

Thanks so much Tony. Yes keep it on in my book too. Does no harm really. Cheers

[@pastorfrankie3120]

loved it on my triglide when i had it. not on my 07 FLHRC

ok cheers

[@DIZEMANPHOTO]

I have a 2002 Road King Screamin' Eagle CVO and don't have an Owner's Manual, anyone know if there is a LIST of which MODEL YEAR bikes have the EITMS feature? Mine was running 277 degrees on a trip between Pahrump and Las Vegas, NV yesterday with myself and my wife. Air Temp outside was 70 degrees, way cooler than our Summer temps of 120 degrees.

[@team_sixthree8956]

Ran into your vid Definitely the dyna 2017 has it always not turning over right after a long ride till it cools off for like 20 minutes getting an oil cooling system for this problem hope it works cheereos

[@aprazdnik]

Brilliant thanks so much for the hint! Maybe I’m missing something but is there a draw back for to not not having this feature enabled?

[@RevelatorAlf]

I would only say if you’re riding in hotter temperatures but otherwise it should be fine. There isn’t a performance reduction with having it enabled so it’s really a personal choice I suppose. Cheers

[@rodzimmerman1979]

@@RevelatorAlf If you have a big cam with a choppy idle when EITMS activates the bike sounds like a Honda 90 so many owners don't like that.

not sure

I had this on my 2010 police roadking ,I have the 2020 streetbob now,and I must have it cause when I’m sitting at lights I can hear the back cylinder shut down,and was worried my engine was bad

[@RevelatorAlf]

Yep, should be normal action. Cheers

[@shadowman5088]

I checked,I have it! Thanks for the vid ,I was concerned

[@HennieBours]

System is for riders comfort (heat production). Nothing to do with overheating second cylinder.

[@philiproberts6947]

Can this be done while the motor is running,and also is this enabled from the showroom? Good info,think you can alter the temperature of this system through the V&H FP3.

[@RevelatorAlf]

Thanks Philip. Yes I'm quite sure you can do this whilst the engine is running too. I'm not sure however if this is enabled as standard from the showroom, however my bike had it already enabled. Perhaps there might be some adjustment in the FP3 however I'm really not sure, however it would be good to know whether the FP3 in anyway affects the EITMS activation parameters. Cheers

[@andrewvickers4487]

Yep with respect the title is misleading, EITMS won't stop your harley from overheating, it kicks in when oil and engine temps are already too high and it doesn't bring them back to optimal (seems aimed at rider comfort). Only real options are fans on the engine and oil cooler. It's ridiculous, decades of big twins roasting in traffic and still no fan-assisted coolers for the new softails as standard (and only aftermarket option is mounting an additional cooler for $550+!)

[@Boobtube.]

so how does this help the front cylinder? That 1 is still generating heat.

[@RevelatorAlf]

It won’t. But the front cyclised is generally cooler and will be cooled more by oncoming air flow. The rear cylinder is almost in its own shell so get even hotter

[@Boobtube.]

@@RevelatorAlf ok, makes sense.

Bro plz help me problem karizma ZMR OverHiting

[@jDot2414]

While this feature is enabled , is it safe to do highway speeds ?? Or is this strictly for traffic flow

[@RevelatorAlf]

It's perfectly fine. cheers

[@RomanVideos1]

Is there a way to check which bikes have an EITMS system on a harley's website?

[@RevelatorAlf]

Not sure. All Softails and tourers have it but not sure if there is a search option

For the better though

[@adrianlopez8796]

I have a question I have a iron 883 I had just put some slip on pipes do I need needa tune it and wil it overheat

[@RevelatorAlf]

I would say not totally necessary as long as the air filter is still standard but it also depends what kind of exhaust you have put on and how that affects the back pressure. If the bike doesn't sound or feel right then your best option would be to tune it, cheers

[@DIZEMANPHOTO]

Anyone who knows... I BBQ a lot and have a digital thermometer... I am willing to carry it in my bag on my 2002 Road King SE CVO to check engine and head temps if that is an accurate and viable way to make sure nothing cracks... I would hope my $450 DynoTUNE Power Vision is giving me the correct temp, but would the digital thermometer confirm, I am thinking it would. (Not a Harley Guy, I just own and ride one. I don't own a single Harley patch or logo if it is not attached to the bike. Just not my gig!)

Hey guys! Would this cause my bike to shut off randomly while riding, backfire, and my speedometer goes crazy. Sometimes revs on its own with clutch in and high idles any gear. It runs amazing when this isn’t happening. Thought I fixed it today, rode it for 30 minutes and it shut off 2 times, revd with clutch in 2 and backfired once. Thanks guys I can’t figure this one out

[@RBoysMedia]

If it was faulty of course

[@RevelatorAlf]

Hmm that’s an interesting one. This sounds like a sensor issue messing with your ECM. Ha e you checked for error codes?

[@RBoysMedia]

@@RevelatorAlf haven’t used a scanner, don’t have one. But there is no engine light coming on. Bike runs great. Every once and awhile it will randomly do one of the problems. Seems completely random. I tried cleaning my map sensor so I don’t think that’s the issue. This is my last guess

Does anybody have any idea what temp it should activate on a twin cam Softail deluxe? My V&H FP3 has it set at 310degrees which seems to high according to my testicles which are being boiled. The bike has a Stage 1 and a Stage 3 and running Samson true duals. Not sure it was this hot before i changed the pipes and added the FP3.

[@RevelatorAlf]

Sorry can’t help you there

[@billgonzales8978]

OIL cooler helps alot?

[@MrJnrc]

Bike was running too lean. I took the bike to a dyno specialist and he reprogrammed the FP3 map as it was way too lean. Might change the FP3 to a power commander 5 and have it dyno tuned. V&H have no idea how to map bikes period. That’s my personal experience with them. I’m sure others have had better luck.

wanna know an easy solution? Long red light? Just sitting? SHUT THE MOTOR OFF. Start it back up when you can move again. Anyone who owns an Evo shovel panhead or iron sporty knows this.

[@amungus76]

I find this truely amazing that Harley decides to keep engine cool by shutting off half of the engine! Other engineering companies just add water cooling system! This is old long time issue. Over heated motors have always been an issue for the life of motors but Harley has fought until recently just getting into the 20 century engineering. Still hard not to luv em.
