Harley Heat Management System, DO NOT OVERRIDE IT
Vložit
- čas přidán 23. 06. 2022
- Harley heat management is a real thing and you may actually be unknowingly overriding the system when you need it the most. Late model fuel injected Harley-Davidson motorcycles have a feature which actually richens the air fuel ratio when high head temperatures are present. If you've ever been sitting at a light and the idle speed drops down around 900 RPMS, that's the heat management system doing its job. Now if you like to rack your pipes at the stop lights, your actually overriding this system and generating more heat when the engine is trying to cool itself down. Harley heat management is another great feature of the late model closed loop fuel injected system which works great if you let it do its job.

Do you have any interesting tips or tricks you use to keep your bike cool in the hot summer?
I installed Harley's oil cooler fan and on blistering days, hold the throttle wide open for 5 seconds prior to starting
to keep the fan on, versus the ecm regulating it
@@carlbruhn1772 Didn't know that was a thing. I knew you could test the fans like that, didn't know you could bypass the ECM. I'll try that out, thanks!
You should do an in depth explanation of the power vision. Things like what it learns on auto tune. Mine still seems to run lean. Is it trying to have balance or more performance. I just started using it so im still learning but I want whats best for longevity and some fun.
If there’s no traffic, I run the lights. Another thing I do is I actively try to avoid traffic lights in part because of that… the other part is… them damn “cagers“ be to busy looking at their phone instead!
G'day GixxerFoo..
Always great content & easy to understand the way you explain things.
Keep Living the FUCKING Dream ❗
Safe travels 🙏❣️
💪🇦🇺💪
Thank you so much for the great video. My friend and I were just talking about this the other day because at every stop light, he cranks on the throttle just to hear it.
That's awesome! Lol I may be guilty of that too, but dang sure not in this weather were having now!
@@GixxerFoo yeah definitely, too hot to be a showoff right now lol.
How much you help people is unbelievable and what you’re doing you’re very easy to understand. Like when you’re talking about lol idle and heating up the motor you said it perfectly I make it all the Way through your videos. Unlike so many videos I usually don’t ever make it through but you are the man
Just shaking my head thinking....gonna stick with my Evo....and carb.
Way simpler and much less complicated, you just can't replace that Evo honestly.
Same thought with my carbureted TC88. No need to change
I love my Evo, but can’t compete with the power of my M8. I’ve put 24k on that Evo, over 15 years, never having to do anything other than basic maintenance. Had to replace/update the oil pump on my M8 before 4k miles. Both serve a great purpose.
40,000.00 miles and still kicking ass 1999 ultra.... stock....
Good info ThankYou!!!!Brother
Excellent advice that, probably, most riders didn't know... God bless y'all!!
Your videos are brilliant,you put them across well👍
Thanks for the explanation of the inner workings of the engine cooling protections. I have a 110 and started it in the garage went inside and totally forgot the bike was running. 45-1 hour later ran out and the bike was running rough and had the worst smell of burnt oil. I immediately shut it off and let it cool down then immediately changed the oil. To my surprise there was no lasting damage with the internal operation and the bike has been running great (2011 RGU CVO) it’s great to understand what happens, the causes and how to prevent mindless mistakes…that’s where you and other knowledge keepers come in, educating those of us who may not know or just need better understanding. You are very appreciated. Keep up the great content! Love It!!!!
EITMS is not for engine overheat but for rider comfort. As per Harley Davidson service manual “To improve rider comfort on all stock touring model motorcycles a optional heat management system” has nothing to do with engine protection. Several people have done testing and proven head temps don’t change when in EITMS
I always thought my bike was getting hot when that happened it idle down and made a funny noise but now I know that's normal thanks for the info Great channel always informative and love to watch it
Great information. Very technical. Your opinion about the fact that lower RPM's means lower oil flow which in turn can make the engine hotter!
Great advise …. 2016 UL rider …. I often at long lights just hit kill switch, for me, why not do all we can for longevity of our beloved Harley’s.. my 103 H.O. has 70.000 miles and is still running perfect (stock bike except 4 inch slash cut S & S pipes) .. simply by common sense, and 3 hole oil changes when needed or even a little earlier then recommended…. And all maintenance that a Harley needs .. love the channel brother …. Content always stellar
I ride a 21 Freewheeler 114. Took a long trip after getting it last summer. Went from high desert AZ back to Oklahoma and she ran hot so this year change out the slip on's and raise the tank 1.5 inches with a small wind deflectors on each side of the tank. Getting my 10k fluid change next week. Then we use a HD tuner on her. And also change out air filter to open her up to better breathing
I had my reservation about an air cooled bike before I bought this old twin cam. I won't make this mistake again. Only thing I can say is as an '04 EG. She isn't totally dependent on the e.c.m. and runs fine. I will put a large oil cooler and that should do it. Pour a cold beer over it when ever to keep her cool like me.🙃
Excellent explanation of the key fundamentals of what's happening behind the scenes in the EFI system GixxerFoo! Also helped clear some misunderstanding on how the EFI mapping tables interact with the tuning parameters.
Thank you! I appreciate it! Bad thing is with narrow band they don't really go below 14.7 but they will allow that afr to climb up to around 15 with the stock mapping.
@@GixxerFoo Thank you
Was in Virginia 3 years ago on my twin cam Ultra, 107 degrees stuck in heavy stop and creep for miles. I nearly pased out but the motor wasn't hurt. The system worked.
I had no idea? That was very good info! We all want to take the best care we can. Over
Unbelievable. Been riding twin cams since '09 and this is the first I've heard "Open Loop at 950 rpm". Thanks so much. I'm in So Cal so this is really important info.
Once they hit temperature the ECM will drop the idle and go to the fuel tables which allows the AFR to richen up temporarily to cool the motor down a bit. It's stupid what the head temperatures can reach on those bikes sitting at idle.
I've noticed that while sitting at a long red. I'm fortunate in that I can choose when to ride and that's mainly either early in the morning or when ambient temperature is cooler. Also my late model runs noticeably sluggish in warmer weather. But in cold or cooler weather it runs very well. Good information there buddy,, keep it coming.
Good video, GixxerFoo! I live in Texas and any tips like this are always welcome.
Right on! I'm in Oklahoma so we have similar weather! It's looking like 100 all weekend around here, not bad as long your rolling.
I have a 2010 Road Glide with a Ultracool oil cooler and the small set of Love Jugs. They keep the bike running cool during hot days.
That’s why I stick to 2000 -2002 bikes. Timken and forged cranks also😊
Fan assisted Jagg Cooler and removed front lowers on 2013 Electra Glide Ultra Limited. Love my Harley. Also had Shop install S and S Cam plate, cam chain tensioners, Oil pump.
Nice! It's crazy how much a high volume oil pump will cool down a motor!
I'm fortunate to live in a county (rural Texas) with a total of 3 traffic lights in 1000 square miles. Lite traffic, no freeways and I have semi retired my 05 Roadking TC88 to cruises when outside temp is 80F or less and then usually only take around 50 to 70 mile loops thru the country a couple of times a month. I've got other bikes to ride in hotter weather that handles the heat much better than the TC's.
You have become a go to for learning for me... im trying to understand mapping and tuning better.. enough to consider going to school for tuning instead of going for mechanics which i know after 20plus years of wrenching... keep up the good hard work
Bin riding a shovel head for 35 years and decided to up grade to a 2014 Street Glide. Good to know. I have that Burn mark. No mention of shutting down the rear cylinder.
I can tell already that I'm going to have to watch it twice,,or three times. Great video Gixx
Wow, thank you! Glad you enjoyed it! It's a real deal with that closed loop FI, head temperature can get stupid high on those bikes sitting there at idle.
@@GixxerFoo Yeah I Hate stoplights and try to avoid them when possible but around town that's just not possible.Love riding out in the Country where there's few stoplights.
Good advice, my old 68 shovel got real cranky sitting at lights on hot days, it loved the cool breezes off the sea.
Those shovels took some straight weight oil and just did what they do and didn't care if you liked it or not!
Something that doesn't get talked about ever, is that you can buy aftermarket cooling fans for the oil cooler that comes on M8's, and it helps a lot.
Harley sells them in the accessory catalog for bikes originally equipped with an oil cooler. Jagg and Ultra Cool have their fan assisted units too, honestly every oil cooler should have a fan.
@@GixxerFoo agreed. In their advertisment video, Harley themselves say their oil cooler fan drops oil temps 50 degrees, which is massive. Seems illogical to me that they would install oil coolers on every M8, and yet not give the cooler a fan.
Wonder if Harley will make oil cooler fans for M8 softails? Looked for 2020 Fat Bob fan with no success.
@@jkmoa415 That would be nice, but us Softail guys always get the short end of the stick from Harley. You could always check the aftermarket, rig one up yourself. Shouldn't be too complicated.
@@PotatoeJoe69 I'll def look around then. In my area of NC, traffic gets funneled into single lanes due to road construction on a whim. So lots of slow creeping without being able to turn off my bike. An oil cooler fan is just the ticket!
Great information! Thanks for the lesson because I did learn some new information.
OK so I ❤️your videos 👍. When I got my 14 Street glide one day it was like running on one cylinder 🤔 Sounded like a bag of nails with practly no power. I got to the dealership that had a master mechanic at the time ( sadly all his replacement's after he left were crap) Anyway I digress. He laughed and put my bike into disable mode. Since then I have put Amsoil ( which is supposed to have good heat dealing properties) and mini mites that at shows they have a bike that sits there all day and didn't move in 85 degree weather. So I take your point but I'll take my chances. Also I never end up reving my motor anyway let alone stopped in traffic with the sun beating down 🤔. As far as cutting your motor and peddling the bike forward then good luck with that 😂on my Deuce maybe ? But forget my 900 lbs Street glide. Keep up the great work 👍😎
Great info thank you. Sold my 2012 Dyna now 2021 Road king. Wow what a difference. Freaked out alittle the first time she got hot and started running on one cylinder at the light😁👍 . Alls good. Just installed a screaming eagle stage 2 . Nice riding motorcycle 👍🇺🇸 thanks for all you do.
That's awesome, glad to hear you're enjoying! I appreciate your support!
Two things: PC 5, unplug the O2 sensors, Stage II. Download a fuel map or dyno your bike with the PC 5 to a richer fuel mixture. Second, ceramic-lined header pipe...makes for better performance and helps funnel that heat away.
As usual quality information in the heads-up category! Keep up the good work...
Great video!! Yes, I'm guilty of 'blipping' the throttle sometimes, too. I will keep this in mind, though, now that it's scorching summer in Arkansas. It was 102 degrees here yesterday, and with the heat from the road + the bike, Lord it was hot.
I Love to ride but when it gets above 90 degrees it takes a lot of the fun out of it,especially waiting for stoplights to change.On those days I try to get out and ride around 7:00 am before it gets awful hot.
Great video! I Had the S.E. Smart auto tuner with the wide band installed to my 16 FLSS seems to run a bit more cooler and The rear cylinder doesn’t shut off as bad like it used to!! Also helped that I change the slip ons with no cat & put a External Breather System.. 😅
That wideband system makes a big difference, plus you get a lot of heat out of there without those cats in the exhaust!
Ive fitted external breather,loveJugs,10 row oil cooler and FP3 fuel park which I can monitor the engine temperature,even when idling at the lights the temperature is well within the prescribed temperature Harley likes you to run at,when stationery with the love jugs running you can actually see the temperature drop,so my experience maybe different to others but that's what I'm seeing I live in Western Australia and we have a hot climate, without the fans, oil cooler and FP3, external breather I think my 2014 Fatboy lo would run a lot hotter.
Watching you frequently from Malta in Europe. Thanks for your tips!!
Thanks, good words before hot Sturgis! I don't have that problem in Alaska.
Fantastic vid. I have a 88 tc carb do they not get as hot? Also today I picked my scoot up with my SS 510 cam Cobra 2into 1 and new air filter NEW PUSH RODS CAMS CAM PLATE OIL PUMP LIFTERS. And I would like to tell you my 2002 Heritage runs like a beast. It may be my age of 61 going on 62 the 88 tc pulls hard almost scary I really don't think I need much more power. Thanks Gixxerfoo for the great vids. I will keep you posted on my transition from wanna be to Reborn again Harley Davidson owner!!!!
Awesome video Gixxer! I’d like to hear your take on FTC’s ruling against H-D Motor Co.
it’s basically a win for ALL of us! It basically boils down to issuing fines for not honoring warranty service because someone else did repair work. There’s also something about OEM vs after market parts, and more. (I’ve read up on it… I’m intentionally being vague to encourage others to look into this for themselves). Hopefully it’s enough to change things
Raises Hand. Great video Foo! Follow up question, how about we are in slow traffic - better to ride in first gear with higher rpm thinking the oil pump will circulate more oil that way, or go ahead and shift up and let the rpm stay as low as possible so the heat doesn't build due to engine speed?
EITMS is one of the best features harley ever put on their air cooled engines period. Thank you you spreading spreading word
But it’s for rider comfort not engine protection
@@johnbrowning1232 the rear cylinder on the motorcycle is the one that gets the hottest when sitting in traffic in the heat. When EITMS is enabled it runs off of Front cylinder only. allowing a lot of the hot air from that cylinder and the exhaust to dissipate. If you're in a really heavy slow down and you're there for more than five minutes you're going to have to shut her down anyway. But if you're at a stoplight on a 105-degree day like I was yesterday and you flipped that sucker on it's cooling it. Those engines have always run hot that's why they do oil cooler stock now because as they get bigger they run even hotter. It definitely will save your head gaskets and your rocker gaskets from getting burnt up sooner than later.
@@mattcottrell3336 yes so the exhaust isn’t as hot for the rider. I did a test with a thermal imager and the rear cylinder temps don’t drop. Per Harley own service manual it’s a rider comfort feature, not a engine cooling feature. But what do I know I only tested it myself, read it’s function in the workshop manual and have only been working on vehicles for 18’years 🤷♂️🤷♂️🤷♂️
@@johnbrowning1232 it's not about the Temps of the heads. Those won't be affected. It's about the heat at the base of the headers and exhaust ports.... in 18 years of working these I would hope you'd seen cylinder sleeves cracked from excessive heat in Harleys? Or leaking base gaskets in evos?
@@mattcottrell3336 As per Harley Davidson service manual “To improve rider comfort on all stock touring model motorcycles a optional heat management system has been included” say it with me optional heat management system for RIDER COMFORT. If it was for engine protection why would they have a way to turn it off and on? Why is it listed as a rider comfort option? Why do people I know that’s disabled the system not have cracked sleeves and other issues from heat?
I added a ultra cool fan forced oil cooler and it helps keep temperatures down when sitting in traffic. I also have love jugs as a backup. I took the mid frame deflectors off because I believe they hold in heat. I thinking of wrapping my pipes next time I have the shields off.
I had a power commander installed years ago on my 07 Dyna, which removed the oxygen sensors, then had it dynoed. I then custom installed a police solo saddle which got me higher above the engine. Plus, I never throttle while sitting at a light.
Great info, thanks for sharing.
That's awesome, went back to doing it old school with an open loop system! You never had heat complaints on the earlier delphi EFI bikes, they didn't have the oxygen sensors.
Thanks, that was very informative. I had no idea Harley was that advanced.
I just put a side mounted Jagg on my 2010 Superglide C. It was easy & i encourage everyone to do it.
It makes a noticeable difference! Did you get the fan assisted model?
@@GixxerFoo No. I figured i'd start with the basic model. I generally never ride in real stop and go for any length of time. I just installed it cause it fun, but both head temps, at the spark plug, after a good ride are 225.
@@GixxerFoo I most likely will get the fan if i'm board one day. I like working on bikes!
14.7:1 is the stoichiometric ratio where the most complete burn happens. It's neither rich or lean. Rich or lean is in reference to either side of this ratio. A smaller number means richer, a greater number means lean.
By definition, a bike cannot be running lean if it's at the perfect stoichiometric ratio (which happens to be 14.7:1).
That sure makes sense...lean or rich has to be referenced from somewhere.
Thanks for some of this info. We often take the way the bike runs for granted
You're welcome, there really is a lot more to a Harley these days with the FI.
You can activate this on purpose . Set course, roll throttle backwards ( as in ahead) and hold. Watch light on dash.
14 fat boy stage 2 with the oil cooler. If I run it below 80 on the interstate my temp goes to 230. Pop off into the city for some side Street city action going slower more gear shifts and my temp goes to 260 after 5-10 miles. I’m at altitude and run 12 months a year, May through September can be challenging if it’s 90+. The worst is 3 to 4 lanes wide interstate, dead stopped w/all the cement that’s when i lane split and get the F out of there!! Lane splitting in my state is illegal, guess I ride dirty
I am huge supporter of lane splitting, you're a sitting duck in traffic with no where to go. If you don't have a fan on your oil cooler that would be a great addition, those really help cool a the bikes down quite a bit!
This is interesting stuff. Often wondered how they kept cool. Australia.
I have mode on my 2018 Heritage that if you are seating at an idol the back cylinder spark shuts down so the back cylinder works like a air pump to cool it down. As soon as you hit the throttle it kick back in an off you go. Good video keep up the good work
That’s awesome info didn’t realize that was happening. Thank y’all for sharing 😎
Your stuff is the best out there. THANK YOU SO MUCH.
Thanks for the info. Wont be blipping at the lights anymore!
Good job on explaining it. So sitting in traffic jams more than 10 minutes is bad. We would benefit our bikes more if we could Lane Split at the 1150 rpms in first/2nd gear to run air over engine. Be nice if Harley could maybe make Open Loop more rich when idling more than 10 minutes to cool down engine if it doesn't cause engine problems. I just can't see some States passing Lane Splitting. Would like to hear what you think 🤔. Or do video on Lane Splitting how it would benefit the bike and people in cages. If the rider doesn't nice Lane Splitting than don't do it. I believe in Low Speed Lane Splitting, my State doesn't believe in any Lane Splitting. Also when the Milwaukee 8 goes bigger to 131 it will run hotter. I know Harley has to meet EPA stuff, put do aftermarket? Maybe a test override switch to run bike rich to cool down riding in parades an desert roads, the back door option for us all.
I had a 2004 Dyna with a fuel injected 88 twin cam and ran into one trip where I was stuck in traffic on a hot day and when the bike got too hot it would misfire. It seemed to be dropping the cylinder in a pattern and I figured it was from either the temps or the computer trying to cool the bike a bit more. I killed the engine and just walked the bike forward as traffic moved. When we were clear of the accident, the bike had cooled enough to not miss when I fired it back up.
Thanks for the interesting information.
Just in time for summer!
Even if u do shut bike off at a red light, it still going to hotter before it starts to cool down. Does shutting it off really do anything
I'm new to Harley bikes with a 2016 street glide special that I just bought. I just took it to the dealership about this. Tuesday it was 91 degrees. Rode the bike home for a 30 min riding on 4 lane highway and it didn't kick in. Got back on it rode 90 miles to the dealer on I-80 and just before i pulled in, the temp on the bike was 83 degrees and it kicked in. Sometimes it would sound like its going to throw a rod or piston out of the block! 1 time it kicked in within 2 or 3 minutes after a startup.
I bought the bike in April and have put 2,000 miles on it for a total of 8,000
The dealership is telling me if I don't like the heat management system on, turn it off! I know better than that.
The question I have to you is, How or what do i need to say to get them to look at the system. I'm told by other owners have theirs on and
they are not having their bikes heat management come.
The heat management system should only activate if you sitting at idle like at light and it will drop the rear cylinder out. But it shouldn't kick on running down the road.
Best thing I ever did to cool my bike down while moving was lift the tank a inch and open up the engine top to air flow... plus the lines of the bike flow better now.
Others have stated how they upgraded their Harley to another brand......I did that too, my 08 Ultra to a 22 Kawasaki Versys 1000.....900lbs is just too much for me to get out and put up........but I also upgraded my 2020 Suzuki GSXS750Z to a 09 XR1200 so I'm still 3 Harley 1 rice burner
Harleys are air cooled thats like the Flintstones. Rice burners are liquid cooled and much more reliable and are a much smoother ride and much cheaper Harleys technology is ancient and there bikes are way over priced a rice burner will leave a Harley in the dust ride smoother and last longer and some even look better
@@adventures223 ever hear "sit your a$$ on some class" ........ You never have, plus you should check out some racing records......and........
czcams.com/video/jXsoAdh5P5g/video.html
I've owned Honda Yamaha Suzuki Kawasaki, I can talk about them based on experience, you clearly talk based on what you've heard that made you feel good about your purchase and it sounded cool
Since '76 , of all the bikes I've had, a 81 Honda 900 and a 2015 Kawasaki have been the only ones had to be worked on other than regular maintenance........ I've had 02, 04, 2-07, 08, 09 Harleys and none of them have been modified.....none of the rice burners have been modified either
The 07 wide glide is the bike I've had longer than any other bike. Both the XR1200 and V-Rod are more fun and more comfortable than the GSXS
that' very interesting. i have i think actually heard a bike idle down, i just thought the person stopped throttling. any way, living in Florida, that's one reason i ride a water cooled Honda. also my old age, skinny ass likes the absence of the extra 200 lbs. Harley's are great bikes, the heat from the engine on any bike rises, so it's hot no matter what you ride. so it's always better to keep moving, instead of stopping for every damn red light.
I ride an 07 street bob and this happens to me all the time. More often than not the motor will completely shut off. Ive told countless techs and they never seem to put a finger on the source of the problem. Should I get a new ECM? And would a Thundermax be a good choice. Love your videos I share them with all my buddies. Keep it up and thank you
Another great video. Can I suggest a video on different types of baffles and what they do. Thanks
I just got my carb rebuilt. I mentioned to you months ago that my 96 1200 stage 4 sporty oil temp runs about 150. Well I checked it last week after ripping all around and its about 140 but the temp was about 65f outside but like I mentioned before the older carbed sporties run so much cooler than the new big ones. Even my stage 4. I have a 99 Honda Valkyrie Interstate gl1500 Flat 6 cyl liquid cooled and its like sitting over a skillet in the hot weather.with all that fairing protection.
The carb bikes run much cooler than the EFI, we could setup an EFI bike to run just as cool as carbed bike with much richer AFR.
@@GixxerFoo carbed bikes sound cooler too
Installed Thundermax on my 2012 103 few weeks ago. Major difference in temp. Runs much cooler.
ThunderMax ECM is a good product and is easy to get help if you need it from support. I have it on my wife’s 117” 2008 FXDB but what really helped was the Zippers Blueprinted Fueling cam plate that raised the relief PSI. Im sure most know the Twin Cam Plate is cast and has potential to leak do to porosity dropping oil pressure below 35 psi. Axtell and Biasley getting a stiffer spring will raise relief.
Blipping the throttle does NOT lean out the exhaust. If it's in open loop and the ECM sees a rapid rise in throttle position, it performs the same action an accelerator pump in a carb does: it injects a larger dose of fuel to prevent the engine from stumbling from fuel starvation on acceleration. It does this by lengthening the injector pulse width to supply more fuel for a few milliseconds. NOW, Blipping and then HOLDING the throttle open for a few seconds while at a standstill CAN lean your engine out and cause a rapid rise in cylinder head temp. Additionally, the drop in RPM at idle when the engine is getting extremely hot is due to EITMS activation: (Assuming EITMS is Enabled) EITMS is Engine Idle Temperature Management System and operates by shutting down (turning off the fuel injector) the REAR cylinder, thus turning it into an air pump, moving cooler intake air through the cylinder and combustion chamber to cool the engine. Hence the lower idle speed. This will be indicated by the Cruise Control indicator turning green while at idle. The throttle sensor must be below 5% and head temp above a preset based on ambient temp, and bike stopped. Any increase throttle sensor, or vehicle speed, or decrease in temps beyond the preset will immediately resume rear cylinder operation and the idle will again rise to approximately 1000 RPM.
What about the engine idle protection by moving the throttle backwards
Good point. But I feel most of us oldies who do blip the throttle are descends of carbies that started to vaporise fuel when hot …lol…
Lol the good old carb days!
2001 Road King, 157,000 and going strong!
I have a 2008 twin cam which I converted to HSR 42 carb, it still runs hot now ! My mixture is slightly rich but man it pushes out some heat in traffic, I think it’s just the nature of that motor 🤷🏻♂️
Its runs hot because its air cooled out dated technology and over priced bikes
Thanks for such great information! I own my first Harley and this information is critical to me! Do you/have you done a video on which bolts/nuts to closely monitor due to a Harley's vibration? Thank you! Always look forward to your content!
Kind of makes me glad that none of my Harleys are fuel injected. I can run them richer. I do run love jugs on the 96 Road King that I removed the fuel injection from.
In 1935 the German Army wanted a motorcycle that would not overheat like the side valve BMWs would at parade speed. The r75 they created does not overheat at parade speed unless you're chasing to French who are running away.
GixxerFoo, this is great information. 👍
So I have a 03 road king with an 88 ci motor and on hot days my check engine light blinks when it over heats so I finally got a set of luv jugs and so far so good but I really try to lay off riding when it's 85dgs with 100% humidity to be honest riding inst that fun when it's that hot to begin with but so far the jugs have kept my bike alot cooler
good info...... I'm in West Tex.... summers are scorchers, and watch oil psi drop to 4# on 110 ultra. I blip the throttle to keep the PSI up ..... time for an oil pump upgrade
Wouldn't hurt at all to run some straight weight oil out there, oil pump wouldn't be a bad idea either!
At high temps you guys have out there, I would SERIOUSLY consider an oil cooler with fan assist (assuming your bike doesn't currently have one). Jagg makes a good one. But even the oil cooler from HD is better than nothing!
Not to mention the automatic rear cylinder shut off that when you goose it this will turn that rear cylinder back on, and thus add more heat.
What about my 95 Evo sportster and softtail with carburetors ?
Really like your show, keep up the good work!
Thanks, Randy
Thanks for the explanation, still learning everyday
Damn straight……Can’t stand those morons that continuously blip the throttle sitting at a light or pulling into a gas station…… great content as always 😉
Love the bmc hat. BFFB
Actually the 14.7 is due to barometric pressure at sea level. That's what the pressure rating at sea level is and what all tuning is based around.
My '09 ElectraGlide or I have this problem. 87 octane seems to help and don't over rev or under drive.
such good info.... Subscribed!
As always, great video. I love my "Love Jugs" good investment and addition to my bike.
Thanks brother great information it has given me something to think about not that it's hot here at the moment just traveled down the north island 1600ks all up didn't get over 10°
All the best brother from NZ 🇳🇿
Wud up Foo! Having a 2002, carb'd to boot, this is a feature I don't really need to worry about but I believe if you roll the throttle forward while in Parade Mode, it'll shut the mode off, or like you said, just rev it. Most of those I know, this feature drives them bananas or they thought something was wrong, naturally.
Thanks for this video. I did not know any of that. I have a TC103 that gets very hot despite having an oil cooler, even if the air temp isn't all that hot. I use an FP3 to monitor the temperature on my phone. I shut it off if I'm at a light that I know is long.
This was very helpful! Thanks!
Very helpful video. Thanks.
Early Fi systems Delphi..? Mag netti marelli..? Would actually drop a spark to lavage the cyl with unburnt fuel. You could hear it stumble a little but it seemed to work ok
Isn't there some kind of "inhibit" feature in the ECM that keeps it from going in and out of open and closed loop modes after just a brief throttle snap? E.g. 2 seconds above 950 rpm would allow for a change in modes? You would think that there would be some form of delay so that wouldn't happen. Look forward to hearing back. Thanks
thanks this happened to me today sitting at a light all of a sudden the rpm dropped , i thought it was going to stall from the heat so i brought the rpm up to keep it going so i wouldnt get run over on green . now i know
Great info... thanks for the heads up.
What about a 2004 ( Road King)... is it the same... I know mine idles down like you described...
Thanks for your input 👍
Love your Channel! I am an EVO guy and love your EVO videos.. Could you do more videos and the all mighty EVO
Great video as usual! Two questions. Does the EITMS have to be turned on for automatic enrichment you described to occur? And is this the same scenario on the M8's? Thanks for the help.
