Prior to my purchase of my external air cleaner, I was having problems with my 2015 flstc stalling when coming to a stop, after investigating I discovered the sensor in the throttle body was getting clogged by all the nasty blow bye oil. Cleaning the throttle body and installing the external breather solved my problem. Thank you for another great product.
Yep, that crap will mess up the sensors for sure. Completely forgot to mention that in the video. Thanks. Glad you're enjoying the EBS from us. We appreciate your business.👍
I am running a se stage 4 and that was causing even more than "normal" oil into the intake. Did the DYI external breather system. Made a difference that you can feel. Hands down biggest bang for the buck. Highly recommend!
I read an article years ago that said that carbon build up could get glowing hot red and cause detonation. I vented to the atmosphere as soon as I got my 2007 Dyna. My oil stays cleaner longer and it uses less oil.
Just ordered my DIY kit for my 2015 Ultra. Took my air filter off today to clean it and was shocked how much oil was behind it! My bike is looking forward to breathing fresh, clean air!
o bought a breather kit because of this video. i didn't know the damage it was doing until a was able to see it. I'm sure my stage 4 will really appreciate it.
Bought a used 2017 Breakout TC with 7K on it and proved for myself the amount of crap on top of the piston after buying a borescope and seeing for myself. The bike didn't move again until a external breather was installed. Thanks guys.👍
Good deal. Yes, so many folks have no idea the crap that is going into their engine, compromising performance and engine longevity. Glad you got it fixed on yours! 👍😎👍
i modified my stock cleaner body w/ a K&N filter. i trimmed the rubber breather lines then ran new ones around the inside to the bottom w/ a T_fitting, drilled a hole then ran a line to the back of my frame. spent 8 bucks. works perfect and my shit looks stock
You guys are exactly right I pulled my 2020 114 apart to install a 128 kit with 1700 miles you should see my pistons wet soot and oil in the intake everybody should have an external oil breather
Yeah, it is amazing how fast and how much can build up. Here is a photo of another M8- www.dkcustomproducts.com/media/wysiwyg/AirCleaners/M8_114_5000_miles.jpg It only had 5000 miles on it when it was pulled apart to go from a 114 to a 131. If you have photos of yours, please send them in to Support@DKCustomProducts.com, attention Kevin. Would like to see them and possible use them on our website or a video.
Ordered the complete 606 air cleaner with external breathers a couple weeks ago but with this covid deal going on the mails extremely slow. Looking forward to this inexpensive mod for next season.
We appreciate your business. I believe you will be well pleased with your new set up. Yes, international shipping has slowed down quite a bit in some areas. I just checked tracking on your order, and it passed thru Toronto yesterday, so you should be getting it any day now.
Agree 100%, I plumbed mine out past the rear fender and my intake is clean. harley sux. They never got the draining of the top end right. That's really the source oil the oil vapor, or outright oil. AND there is nothing in the cam chest that's right. Their scavenging sux, cam plate sux, pressure relief valve sux. Even if you boost pressure relief valve tension, it will have more oil in the rocker boxes and won't scavenge it. I run S&S TC3 cam plates and oil pumps with a third gerotor with three quarts of oil and don't feed back into the intake. My bike and all of the bikes I've done this to have clean intakes. Sorry, no help for already carboned up pistons from before these changes. That's an entirely new thread on how far to go to clean up that mess.
Glad you got yours taken care of with an External Breather System. Agree with you on the other points, although, most will not spend that money or time.
You guys announced at the beginning that you would explain what an EBS is. You explained the benefits of an EBS but I still don’t know what it is or even what it looks like. It would have been nice to plainly say what is and show pics of it.
Sorry it was not more clear. Here is a link that shows exactly what a EBS is, and below that link is a link for all different kinds of External Breather Systems. www.dkcustomproducts.com/overview-of-external-breather-systems-ebs.htm www.dkcustomproducts.com/breather-systems-c21.htm
Are you talking about the photo in the link below? That is my Sporty and I've had it there for well over 20K miles. Never had any problem. I've kept an eye on it and if there was enough oil coming out that it got on the tire or rotor I would switch it up. I do have some bikes that spit more, and would not locate it there on those bikes. www.dkcustomproducts.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/b/r/breather1_1.jpg
I asked about External Breather Systems when I picked up my 2021 Heritage Softail. The dealership explained it "MIGHT" void the warranty. So I will wait until the warranty expires before I drill into the backing plate.
Your dealer was correct on your 2021. The other option is to get a performance air cleaner that comes with an EBS. If you have to take your bike in for warranty work (hope that never happens), then remove the performance air cleaner and reinstall the factory air cleaner. That way you get the better performing bike and never need to be concerned about voiding the warranty.
No B.S!!! Ran two of my bikes with stock set up and then when I went big bore or a rebuild on both after 6 to 8 months of riding each the chambers and the pistons and the intake were all a carbon oily mess! Then after external breathing was installed and the top ends were cleaned I ran both bikes for a year or more. I had to remove exhausts for a pipe swap and the one bike had a common intake seal leak that required a throttle body removal. Both the intake runners, the throttle body and the exhaust runners had NO build-up at all - just a light grey brown colouring from fuel. External breathing whether by kit or by a home job WORKS! No debate! P.S. The tune on each bike never drifted - period!
This is the same issues cars have, currently the solutions are use synthetic oils, Valvoline seems to be the best because it evaporates the least, use a quality gas that has additives in it Shell seems to sell the best, since it has the most cleaners. Oil catch cans can be beneficial, but they cause their own problems with vacuum (oil breaks down most of the tubing people are using) it causes performance losses and if you do not empty it, it makes the problem WAY worse. The final solution is to take the engine apart and use a walnut blaster and clean the carbon off directly.
Yes, Yes and Yes. What most folks do with cars that they are trying to get the best performance out of is use a catch-can. I was just looking at a 4 cylinder with a turbo that produces over 600 RWHP 2 days ago. One of the first things the owner did on it was install a catch-can.
My question to you gentlemen should I void my warranty to do this and save my engine or should I do it after the warranty is up thanks for the good videos
Thanks, glad you are enjoying the videos. I propose another option. Use this to increase your power, tune stability and engine longevity. If you need to take your bike in for warranty work, remove it and return it back to stock before taking it in. There is yet another option, but only makes sense if there are a lot of things you want to do to your bike, but feel you are being held back by the ridiculous HD warranty restrictions. You can see a video we made on it here- th-cam.com/video/p8U4XsHyBug/w-d-xo.html
@@DKCustomProducts also on the install videoat 2:02 you say it is crucial to cover the two existing holes on the back cover.can i asked what you used for that?
@@fastone136 High heat RTV with a nipple (blob) on the outside so it can't get sucked in. Also have threaded and used bolts or set screw with thread-locker. Both work, just your preference.
You failed to mention several very important aspects, it's not only oxygen depleted oily residue it aslo contains 80% condensated water molecules. Also that it fouls the IAT Sensor causing high startup Idle, high revs in lower gears and often causes the engine to die at very low speeds/manouvering. That on early twin cam engines the IAT Sensor was external to the inlet tract so if fouled needed a strip and clean or would not go away. On later bikes the IAT Sensor was moved into the tract and helped to stay clean as washed with fuel. It still gets fouled and although it deals with it it only does so with the asociated issues first mentioned above. Just spotted below you realise you forgot this extremely important information as this is what has customers re visiting the dealers on numerous occassions and being charged for an IAT Sensor clean. £50 or $60 at a time. Fitting of a breather setup and catch can on early Buell X1 Lightening bikes was completely standard practise as those engines produced a ton of goop. Force Engineering developed a breather and venting system as standard to help cope with it but no decent catch cans like you make. Force filters dont look very good on a big harley. I purchased a DK Customs Catch Can its a crying shame are no dealers supplying them in the UK.
What bike do you have? You may find this video useful- th-cam.com/video/rWOdQOtDv6A/w-d-xo.html There should not be more than a 10-20 degree difference in engine temps (once warmed up) even with the bigger difference in ambient temps you listed.
I just ordered an EBS from you for my 2020 Heritage 114. Do you know if the the detergent in the gas will eventually clean off the carbon on the piston and valves that have already built up after I install the EBS or should I run a cleaner thru the system?
With time (miles) it will to some degree...more so if you ride at higher revs every now and then. We appreciate your business, and I believe you will be well pleased with your new set up. 👍
You do not. The sooner you stop putting that nasty stuff in, the better. Once you are feeding only clean, cool, oxygen rich air, it will eventually clean itself out, or you can speed up the process using some Sea Foam or some other additive.
I love y'all's videos. I have a question that probably most people have. What if you did tune etc. but it's been a few years and miles ago. Can I install a breather system and will it help? Or do I need to clean cylinders and valves to get any benefits from external breathers? Thank you for your time. 2008 fatbob 22000 miles.
Yes, you will get an immediate benefit from installing and External Breather System. No more hot, oxygen depleted, oil air going into the combustion chambers will result in more power and a bit cooler running. Regarding build up that is already there, as you ride, it will eventually burn off. But there are things you can do to accelerate the process, and to clean out your throttle body (which will not burn off like the deposits on the pistons) and we have a video on that subject here- th-cam.com/video/kCw6coYjsnI/w-d-xo.html
Since the vented dipstick and the vented crankcase do NOT stop all the hot, oily, oxygen depleted air from going into the intake, and all of the External Breather Systems at the following link DO stop all that from going into your intake, the EBS is the best option. www.dkcustomproducts.com/breather-systems-c21.htm
Love the channel! Keep doing a great job guys. I have installed your High-Flow Air Intakes in both of my bikes with the brass breather bolts. Is this the same as the crankcase ventilation?
Thanks man. Good to hear you're liking the videos. Yes, the crankcase pressure is relieved up thru the pushrod tubes into the breather bolts, so with the brass breather bolts you are getting the crankcase ventilation. We appreciate your business. 👍
if you have a new m8 bike you really need to put a breather system on it unless your pulling the pistons and installing good rings because once you seal up the combustion you don't really need breather systems on my 128 i still keep my dipstick breather and a/c breather but don't have to now because nothing comes out anymore.
@@DKCustomProducts don’t about 100% but once I got them stock rings out of it I can pull the breather hoses and there is nothing inside of them at all. its all in the machine work i run s&s cylinders that were dam close to perfect i have had ones that wasn't total seal rings and cp pistons Iam ocd about putting engines together i try and get them perfect to the best of my ability.which equals a dam good running engine
Great informative video! I have a 21 883. I still have the stock air cleaner. Does this EBS only apply to aftermarket air cleaners? And if I change to a aftermarket air cleaner I assume I should buy an air cleaner that has already the EBS? Sorry, one last question, if I do a aftermarket air cleaner do I need to buy a tuner? Thank you.
Good questions, thanks for the comment. 1. External Breather Systems work just as well, & even are a bit more important with the stock air cleaner...because it will help make up for the hotbox that is the stock air cleaner. 2. It is probably best to buy an aftermarket that comes with an EBS, a bit easier install, and less expensive. 3. On the 21 Sportys they run a bit lean, so they will definitely run better with a tuner, however, if you leave the exhaust stock and only go with an aftermarket air cleaner, it is not necessary to get a tuner. Feel free to call or email to find out which EBS will work with your stock air cleaner. Support@DKCustomProducts.com or 662-252-8828
I'm installing the TTI, and the External Breather system w/catch can in the next few weeks, my 17-103 has 12,000 miles on it, will I be good to go or do I need to worry about a Tune right away ?
On your 103 Twin Cam, if it already has a good tune, adding the TTI's and an EBS will not necessitate a new tune. If you do not already have a good tune, the TTI's and EBS will not make it a good tune. Here is a video that you may find useful- th-cam.com/video/gOeJ6Mx_mQo/w-d-xo.html KP
@DKCustomProducts did the EBS on mine 2 weeks ago & wow it feels like a drag bike & I’m not kidding. It had 108 hp & 116 TQ before the EBS. Only problem is I hope I’m not lean now. What say you DK ? IF Running a canned map will the EBS lean down the mix enough to have to re -dyno it ?
You must have a pretty good amount of oil carryover. Glad you are enjoying the mod. No, it will not lean it out. If your tune was good before, it still is.
@@DKCustomProducts Thanks Plugs show borderline lean before the mod. So with the cold air up here worries me a little. Yes had a good bit of carry over When I took air filter off oil dripped on the cam cover. Don’t know why , I put new umbrella valves in about 7000 miles ago.
@@scrumthebum2451 Do you have a fuel injected bike? If so, can't depend on reading the plugs the same way as you do on a carbed bike. Fuel Injected bikes will always read a bit lean (even if they're not) unless you hit the kill switch (and pull in the clutch at the same time) while going at speed. Then you can coast to a stop and pull the plugs and get a read like on a carbed bike.

I have a 2013 try glide 58 k miles and 2015 road glide 27 k miles will installing external system reverse effect of internal breathing system all this time
I ran a few tanks with Seafoam in the fuel (2oz per gallon) after making the conversion, just to hopefully help clean things up a bit. I don't run at high revs often, but the engine did seem to start running better after a while. It'd only had about 5400 miles on it when I got it, but it sat for a few years and was pretty gummed up. I've also noticed that if I shut the engine off too soon after coming to a stop, it tends to burp oil out of the banjo bolts on my EBS, but if I let it idle down for at least 15-30 seconds before shutting off, it seems less likely to do that.
Im doing a 1275 kit on my 07 883. Its coming with the HPI 55mm throttle body which comes with its own air cleaner so im not sure how it will go together yet, are you guys familiar with the HPI cleaners? I'll probably have to DIY it again.
If you are getting the 55mm HPI TB for the Sporty, it will probably come with the Billet Pro air cleaner. HPI makes an External Breather kit for their Twin Cams and M8's...maybe they have them for the Sportys by now. If not, once you get it, check with us and we'll see what we have that will work.

With a 40,000 mile twin cam that has just installed your external breather, the carbon build up that is preexisting, will this breather help the motor burn it off naturally?
Good deal, thank you for your business, I believe you will be very happy with the EBS. 👍😎👍 Yes, the carbon build up will burn off now that you have an EBS installed and are not constantly feeding more oil in there. Here is a video we made on your exact question- th-cam.com/video/kCw6coYjsnI/w-d-xo.html KP
I'm working on a 103 with black plugs and black combustion chambers. The bike does not burn oil, so without removing the heads and just re-routing the breathers will the engine eventually burn all that crap off, or should it be tore down and cleaned?
It will eventually burn all that crap off once you get an EBS installed. Periodic running at higher RPMs will help it burn off a little faster. Some folks say adding Seafoam or other additives to the fuel speeds it up some. We have never done any testing to see if that is the case.
It will really depend on what Air Cleaner you have. You can contact our customer service so they can help you get the right EBS at support@dkcustomproducts.com or call 662-252-8828. Our EBS range from 69.95 - 224.95.

I've been debating on getting an external venting system for my screamin eagle 128ci motor. I've been looking at vented dipsticks or external breather for air cleaner. Which would you say is better or can you run them both at the same time?
Good question. The vented dipstick does not eliminate hot, oily, oxygen depleted air from going into the intake. For that you will need an External Breather System. However, a vented dipstick is good for relieving excessive crankcase pressure. For most this is not an issue, but with your 128ci you probably do have higher than normal CCP and a vented dipstick will work for that. There are no issues with running both, and in your situation, I would run both.
Only if you have the older oil pump (pre-2020). If you do have the older oil pump and do not want to take the time or money to replace it, the vented transmission cover is a stop-gap (band-aid) until you can get the newer oil pump in order to reduce the chance of sumping. If you have a 2020 or newer, you already have the newer oil pump and there is no need for it.
@@DKCustomProducts thanks for reply, I have a ‘22 RK and a lot of people say to vent crankcase due to blow by and excessive crankcase pressure therefore reducing oil mist coming from breather bolts. Sumping is not a concern but CC pressure is. Thoughts?
@@rtbt8185 If it is a stock or Stage I 2022 M8 it is not going to have excessive CC pressure. It will have hot, oily, oxygen depleted air going into the intake, and that is bad. That is the reason to use an External Breather System. The trans vents and dipstick vents do NOT eliminate all the hot, oily, oxygen depleted air from going into the intake. An EBS does eliminate it 100%, and at the same time, it relieves the normal amount of CC pressure that exists. Link to EBS options- www.dkcustomproducts.com/all-twin-cam-engines-c76-244.htm You can spend the $ on a dipstick or trans vent, but to stop that crap from going into your intake, you will also need an EBS, and the EBS will also relieve that normal amount of pressure, so no need to double spend. IF you have an aggressive cam, or higher than OEM compression, that will create some extra CC pressure, then it can be useful to have a trans or dipstick vent And an EBS.

I wouldn’t have believed this if I didn’t lose my motor to carbon on top of my cylinders and then causing piston slap on only 15,000 miles and two years old. It caused cylinders and pistons ruined. Believe it. It’s a real m8 problem.
Many, sorry to hear about your ride. Hopefully it happened before warranty was up and you got a new top end out of it. Yeah, people say the HD engineers know what they are doing and who are we to second guess them. There are two things to consider: 1. They do know, but they have the EPA to be concerned about. 2. They do know, but so do the accountants who know that most Harley's don't get ridden more than 10K miles before the warranty is up.
Does what matter? They both lubricate well. All things being equal, the synthetic will last longer before breaking down and will also run a few degrees cooler.
Capturing the crankcase oil in a catch-can to make the engine last longer (so less metal has to be used, less manufacturing has to be done, less gas has to be burned) is infinitely better for the environment that getting poor MPG, and trashing an engine. The few ounces of oil out of the catch-can go in the same container as the oil that was changed out, for proper disposal.
Good Question. The following is an answer from a Service Manager at a Harley Dealership- NO... THE EBS WILL NOT VOID THE WARRANTY INSTALL OF AN AFTERMARKET TUNER WILL "BLOCK THE VIN" NO WHERE IN THE GLOBAL WARRANTY DOES IT STATE THAT ALTERING THE BREATHER SYSTEM WHILE LEAVING THE AIR CLEANER IN PLACE TRIGGERS A "VIN BLOCKING EVENT" THE ONLY THING THAT YOU MIGHT GET TAPPED FOR WOULD BE ALTERING AN EMMISSIONS CONTROL DEVICE IF PEOPLE ARE REACHING AND THEN....IT WOULD HAVE TO BE A LIVE PERSON TAKING THE TIME TO REPORT THE ALTERATION TO THE MOTOR COMPANY.
Only if you take your bike in for engine warranty work and the tech sees it and notes it. The digital tech cannot detect it. I would use the EBS, and if I had to take it in for warranty work I would remove it and put it back stock. Only takes a few minutes to put it back to stock.

The most power gain can be had from a 636v that you can see at this link- www.dkcustomproducts.com/outlaw-hiflow-636v-air-cleaner-system-harley-milwaukee-eight-dk-ac-636v-m8-cs.htm Very close behind it is the 828, which you can see at this link- www.dkcustomproducts.com/milwaukee-eight-outlaw-hiflow-828-air-cleaner-complete-systems-40.htm The 587 and 606 are both round style and very close in power gains to each other. You can see them at this link- www.dkcustomproducts.com/air-cleaner-intake-c10-315.htm They all (except the 636v) have many different choices on covers for different looks. Also, here is a link to a video that talks some about each of them. th-cam.com/video/xP7wxWQmSa8/w-d-xo.html
@@hankhamern5456 Cool- the breather kit will keep the crap out of the engine. The vented dipstick will be there to hopefully take care of any temptation the bike might have to sump. We have a video planned where we will be installing some different vented dipsticks on an M8 (that does not have a sumping issue) along with one of our EBS kits. We will be testing how much air is vented via the EBS and how much via the VDS. Should be really interesting.
Nothing to get anxious about. Thousands upon thousands run their bikes with no EBS and they don't breakdown or blow up. This is something to do that will extend engine life, and also give more power all thru that life. It's a nice mod that will save some $ in the long run and give a nice bump in performance.
They're selling bikes like hot cakes right now in my state. I've been looking for a Softail standard for a few months but they are all on hold and sold out right away. Meanwhile the local indian dealership closed down.

@@0100000101001100 Yep, HD is shipping very few bikes to dealerships between now and the end of the year. They are having supply chain issues, just like so many other companies.
Companies like this thrive off of poorly designed bikes that have historical issues of poor performance, high maintenance costs and piss pour reliability. HD doesn't give a rats ass to build a better bike. To do so would costs money. A lot of money which they don't have. So, just slap together new parts of an old design, paint it shinny colors, then call it a new bike. Rinse & repeat. They've been doing this for decades and they're running out of time. Once the boomers die off (and they are) the new influx of young potential buys would rather buy a Tesla.
Thanks for the comment. Lotta truth in your post, also seems like a lot of erroneous stereotypes. Harleys are more powerful, more comfortable, more reliable than they have ever been.

Prior to my purchase of my external air cleaner, I was having problems with my 2015 flstc stalling when coming to a stop, after investigating I discovered the sensor in the throttle body was getting clogged by all the nasty blow bye oil. Cleaning the throttle body and installing the external breather solved my problem. Thank you for another great product.

I read an article years ago that said that carbon build up could get glowing hot red and cause detonation. I vented to the atmosphere as soon as I got my 2007 Dyna. My oil stays cleaner longer and it uses less oil.
Yes, that is true. You did your bike a favor!

Yes, international shipping has slowed down quite a bit in some areas. I just checked tracking on your order, and it passed thru Toronto yesterday, so you should be getting it any day now.
Agree 100%, I plumbed mine out past the rear fender and my intake is clean. harley sux. They never got the draining of the top end right. That's really the source oil the oil vapor, or outright oil. AND there is nothing in the cam chest that's right. Their scavenging sux, cam plate sux, pressure relief valve sux. Even if you boost pressure relief valve tension, it will have more oil in the rocker boxes and won't scavenge it. I run S&S TC3 cam plates and oil pumps with a third gerotor with three quarts of oil and don't feed back into the intake. My bike and all of the bikes I've done this to have clean intakes. Sorry, no help for already carboned up pistons from before these changes. That's an entirely new thread on how far to go to clean up that mess.
Glad you got yours taken care of with an External Breather System. Agree with you on the other points, although, most will not spend that money or time.
Keep your cool, and keep it powerfully clean.

I asked about External Breather Systems when I picked up my 2021 Heritage Softail. The dealership explained it "MIGHT" void the warranty. So I will wait until the warranty expires before I drill into the backing plate.
Your dealer was correct on your 2021. The other option is to get a performance air cleaner that comes with an EBS. If you have to take your bike in for warranty work (hope that never happens), then remove the performance air cleaner and reinstall the factory air cleaner.
That way you get the better performing bike and never need to be concerned about voiding the warranty.
No B.S!!! Ran two of my bikes with stock set up and then when I went big bore or a rebuild on both after 6 to 8 months of riding each the chambers and the pistons and the intake were all a carbon oily mess! Then after external breathing was installed and the top ends were cleaned I ran both bikes for a year or more. I had to remove exhausts for a pipe swap and the one bike had a common intake seal leak that required a throttle body removal. Both the intake runners, the throttle body and the exhaust runners had NO build-up at all - just a light grey brown colouring from fuel. External breathing whether by kit or by a home job WORKS! No debate! P.S. The tune on each bike never drifted - period!
Thank you for sharing your experience. It really does make a significant difference.
Have done this before. It definitely works great.
👍
This is the same issues cars have, currently the solutions are use synthetic oils, Valvoline seems to be the best because it evaporates the least, use a quality gas that has additives in it Shell seems to sell the best, since it has the most cleaners. Oil catch cans can be beneficial, but they cause their own problems with vacuum (oil breaks down most of the tubing people are using) it causes performance losses and if you do not empty it, it makes the problem WAY worse. The final solution is to take the engine apart and use a walnut blaster and clean the carbon off directly.
Yes, Yes and Yes. What most folks do with cars that they are trying to get the best performance out of is use a catch-can. I was just looking at a 4 cylinder with a turbo that produces over 600 RWHP 2 days ago. One of the first things the owner did on it was install a catch-can.
My question to you gentlemen should I void my warranty to do this and save my engine or should I do it after the warranty is up thanks for the good videos
Thanks, glad you are enjoying the videos.
I propose another option. Use this to increase your power, tune stability and engine longevity.
If you need to take your bike in for warranty work, remove it and return it back to stock before taking it in.
There is yet another option, but only makes sense if there are a lot of things you want to do to your bike, but feel you are being held back by the ridiculous HD warranty restrictions. You can see a video we made on it here- th-cam.com/video/p8U4XsHyBug/w-d-xo.html
Will I need to retune after installing ?
No. The installation of an EBS does not require a change in tune.

@@DKCustomProducts also on the install videoat 2:02 you say it is crucial to cover the two existing holes on the back cover.can i asked what you used for that?
@@fastone136 High heat RTV with a nipple (blob) on the outside so it can't get sucked in. Also have threaded and used bolts or set screw with thread-locker. Both work, just your preference.
You failed to mention several very important aspects, it's not only oxygen depleted oily residue it aslo contains 80% condensated water molecules. Also that it fouls the IAT Sensor causing high startup Idle, high revs in lower gears and often causes the engine to die at very low speeds/manouvering. That on early twin cam engines the IAT Sensor was external to the inlet tract so if fouled needed a strip and clean or would not go away. On later bikes the IAT Sensor was moved into the tract and helped to stay clean as washed with fuel. It still gets fouled and although it deals with it it only does so with the asociated issues first mentioned above. Just spotted below you realise you forgot this extremely important information as this is what has customers re visiting the dealers on numerous occassions and being charged for an IAT Sensor clean. £50 or $60 at a time. Fitting of a breather setup and catch can on early Buell X1 Lightening bikes was completely standard practise as those engines produced a ton of goop. Force Engineering developed a breather and venting system as standard to help cope with it but no decent catch cans like you make. Force filters dont look very good on a big harley. I purchased a DK Customs Catch Can its a crying shame are no dealers supplying them in the UK.
Thank you for your add.
All good info!
I know you have told in another video. Whats the best operating temperature in 50-60 degree weather and 80-90 weather
What bike do you have? You may find this video useful- th-cam.com/video/rWOdQOtDv6A/w-d-xo.html There should not be more than a 10-20 degree difference in engine temps (once warmed up) even with the bigger difference in ambient temps you listed.
Dyna wide glide 2016 thanks 230* target temp
@@willwalker5594 Yeah, that would be the max target temp for normal riding on a hot day. I would expect to see around 210-220 on a cooler day.
I just ordered an EBS from you for my 2020 Heritage 114. Do you know if the the detergent in the gas will eventually clean off the carbon on the piston and valves that have already built up after I install the EBS or should I run a cleaner thru the system?
With time (miles) it will to some degree...more so if you ride at higher revs every now and then. We appreciate your business, and I believe you will be well pleased with your new set up. 👍
Do you need to do a top end cleanup to get rid of the buildup before you vent the system
You do not. The sooner you stop putting that nasty stuff in, the better. Once you are feeding only clean, cool, oxygen rich air, it will eventually clean itself out, or you can speed up the process using some Sea Foam or some other additive.
@@DKCustomProducts thanks.
I love y'all's videos. I have a question that probably most people have. What if you did tune etc. but it's been a few years and miles ago. Can I install a breather system and will it help? Or do I need to clean cylinders and valves to get any benefits from external breathers? Thank you for your time. 2008 fatbob 22000 miles.
Yes, you will get an immediate benefit from installing and External Breather System. No more hot, oxygen depleted, oil air going into the combustion chambers will result in more power and a bit cooler running.
Regarding build up that is already there, as you ride, it will eventually burn off. But there are things you can do to accelerate the process, and to clean out your throttle body (which will not burn off like the deposits on the pistons) and we have a video on that subject here- th-cam.com/video/kCw6coYjsnI/w-d-xo.html
Which external breather set up is best? Vented dipstick, vented crankcase, or from the air cleaner to catch can?
Since the vented dipstick and the vented crankcase do NOT stop all the hot, oily, oxygen depleted air from going into the intake, and all of the External Breather Systems at the following link DO stop all that from going into your intake, the EBS is the best option.

if you have a new m8 bike you really need to put a breather system on it unless your pulling the pistons
and installing good rings because once you seal up the combustion you don't really need breather systems

Great informative video! I have a 21 883. I still have the stock air cleaner. Does this EBS only apply to aftermarket air cleaners? And if I change to a aftermarket air cleaner I assume I should buy an air cleaner that has already the EBS? Sorry, one last question, if I do a aftermarket air cleaner do I need to buy a tuner? Thank you.
Good questions, thanks for the comment.
1. External Breather Systems work just as well, & even are a bit more important with the stock air cleaner...because it will help make up for the hotbox that is the stock air cleaner.
2. It is probably best to buy an aftermarket that comes with an EBS, a bit easier install, and less expensive.
3. On the 21 Sportys they run a bit lean, so they will definitely run better with a tuner, however, if you leave the exhaust stock and only go with an aftermarket air cleaner, it is not necessary to get a tuner.
Feel free to call or email to find out which EBS will work with your stock air cleaner.

@@DKCustomProducts
Thanks 👍
I ran a few tanks with Seafoam in the fuel (2oz per gallon) after making the conversion, just to hopefully help clean things up a bit. I don't run at high revs often, but the engine did seem to start running better after a while. It'd only had about 5400 miles on it when I got it, but it sat for a few years and was pretty gummed up. I've also noticed that if I shut the engine off too soon after coming to a stop, it tends to burp oil out of the banjo bolts on my EBS, but if I let it idle down for at least 15-30 seconds before shutting off, it seems less likely to do that.

This mod has no perceptible affect on the oil pressure. It will make the engine run better and cleaner.

Have to add it runs smooth and has crisp throttle response since the breather has been added
Good deal, thank you for your business, I believe you will be very happy with the EBS. 👍😎👍
Yes, the carbon build up will burn off now that you have an EBS installed and are not constantly feeding more oil in there.
Here is a video we made on your exact question- th-cam.com/video/kCw6coYjsnI/w-d-xo.html

@DKCustomProducts appreciate the quick response makes perfect sense. Thank you again
Glad to help! MB
I'm working on a 103 with black plugs and black combustion chambers. The bike does not burn oil, so without removing the heads and just re-routing the breathers will the engine eventually burn all that crap off, or should it be tore down and cleaned?
It will eventually burn all that crap off once you get an EBS installed. Periodic running at higher RPMs will help it burn off a little faster. Some folks say adding Seafoam or other additives to the fuel speeds it up some. We have never done any testing to see if that is the case.

It will really depend on what Air Cleaner you have. You can contact our customer service so they can help you get the right EBS at support@dkcustomproducts.com or call 662-252-8828. Our EBS range from 69.95 - 224.95.
I have an Arlen Ness Method Clear Sucker Air Cleaner Kit For Harley M8. Trying to figure out which kit to use.
Any of the EBS's found at the link below will work with that A/C.

I have a 2014 Heritage Softail Classic to my knowledge air breather system is stock. I would like to do this mod, what kit do I need to look the best. Also I do not want to alter my stock air breather housing eg.. do not want to drill holes in it. Is there such a kit?
If you remove the cover of the air cleaner, and take a photo and send it to Support@DKCustomProducts.com asking the above question. Dwayne or Lela will see which stock air cleaner you have and if what you are asking is possible.
I recently bought a 2019 Tri Glide from a private individual. It has 3800 miles. If I install this will it eventually burn off any buildup that may already be there?
Yes, it will burn most of it off over a period of time, but it will start running better/stronger right away.
CONGRATS on your new to you Tri Glide!
So what kit would I need to do this to my 2012 Harley Seventy-Two that has a Arlen Ness Big Sucker on it now and keep the Arlen Ness on it? Will the simple OutLaw Brass breather bolts for Sportster work?
With the AN BS the kits that will work are the DIY options seen at this link- www.dkcustomproducts.com/diy-external-breather-systems-333.htm

I've been debating on getting an external venting system for my screamin eagle 128ci motor. I've been looking at vented dipsticks or external breather for air cleaner. Which would you say is better or can you run them both at the same time?
Good question. The vented dipstick does not eliminate hot, oily, oxygen depleted air from going into the intake. For that you will need an External Breather System.
However, a vented dipstick is good for relieving excessive crankcase pressure. For most this is not an issue, but with your 128ci you probably do have higher than normal CCP and a vented dipstick will work for that.
There are no issues with running both, and in your situation, I would run both.
Hi, just bought a road king special w 114 m8
Do you recommend installing a vented transmission top cover ? Thanks
Only if you have the older oil pump (pre-2020). If you do have the older oil pump and do not want to take the time or money to replace it, the vented transmission cover is a stop-gap (band-aid) until you can get the newer oil pump in order to reduce the chance of sumping.
If you have a 2020 or newer, you already have the newer oil pump and there is no need for it.
@@DKCustomProducts thanks for reply, I have a ‘22 RK and a lot of people say to vent crankcase due to blow by and excessive crankcase pressure therefore reducing oil mist coming from breather bolts. Sumping is not a concern but CC pressure is. Thoughts?
@@rtbt8185 If it is a stock or Stage I 2022 M8 it is not going to have excessive CC pressure. It will have hot, oily, oxygen depleted air going into the intake, and that is bad. That is the reason to use an External Breather System. The trans vents and dipstick vents do NOT eliminate all the hot, oily, oxygen depleted air from going into the intake. An EBS does eliminate it 100%, and at the same time, it relieves the normal amount of CC pressure that exists.
Link to EBS options- www.dkcustomproducts.com/all-twin-cam-engines-c76-244.htm
You can spend the $ on a dipstick or trans vent, but to stop that crap from going into your intake, you will also need an EBS, and the EBS will also relieve that normal amount of pressure, so no need to double spend.
IF you have an aggressive cam, or higher than OEM compression, that will create some extra CC pressure, then it can be useful to have a trans or dipstick vent And an EBS.
@@DKCustomProducts awesome sir I appreciate it all the detailed info. I installed an EBS on my previous bike from you guys and will do again with this bike.
@@rtbt8185 Thank you, we appreciate your business, and I believe you will be well pleased with the benefits on an EBS on your 114 M8

Can your stage 1 breather kit reuse the stock M8 filter cover, or can I use a Ness Big sucker style with stock air filter cover and your breather/catch can kit ? Thanks.
Yes, the link below is for our Stage I air cleaner, that uses your choice of External Breather Systems (part of the kit, see drop down menu) It is specifically designed to work with the OEM cover.

@@DKCustomProducts Thank You Sir. Not to thrilled about the drilling and tapping part. Do you have similar solution for a TC 88 ?
@@wb4514 I hear you...it is a bit of a jump, easy to do once you do it, but sort of a block against it. That first link gives you the option to use an EBS with NO drilling, with a great air cleaner and still use the OEM cover.
For a TC 88, with a football (oval cover) you can get this air cleaner and run the OEM cover on it- It gives you a choice of many bolt on (no drilling) EBS's- www.dkcustomproducts.com/complete-hiflow-587-air-cleaner-sano-black-for-harley-twin-cam-dk-ac587-blk-tc.htm
If you want to keep your stock air cleaner and just run an EBS, you can use this EBS- www.dkcustomproducts.com/external-breather-system-w-catch-can-harley-twin-cam-dk-tc-brt-cc.htm
But if you have a Ness BS air cleaner on the TC 88, it is the same drill type EBS linked originally.
@@DKCustomProducts What size is the tubing that you use ?
It depends on which type of HD engine, and which EBS kit. Anywhere from 1/4" to 3/8".
I wouldn’t have believed this if I didn’t lose my motor to carbon on top of my cylinders and then causing piston slap on only 15,000 miles and two years old. It caused cylinders and pistons ruined. Believe it. It’s a real m8 problem.
Many, sorry to hear about your ride. Hopefully it happened before warranty was up and you got a new top end out of it.
Yeah, people say the HD engineers know what they are doing and who are we to second guess them. There are two things to consider:
1. They do know, but they have the EPA to be concerned about.
2. They do know, but so do the accountants who know that most Harley's don't get ridden more than 10K miles before the warranty is up.
Excellent video... :-)
Thank you very much! 👍
Does it matter if it’s regular oil or sinthetic oil
Does what matter? They both lubricate well. All things being equal, the synthetic will last longer before breaking down and will also run a few degrees cooler.
So glad you guys support a clean environment…another reason cagers think bikers are morons
Capturing the crankcase oil in a catch-can to make the engine last longer (so less metal has to be used, less manufacturing has to be done, less gas has to be burned) is infinitely better for the environment that getting poor MPG, and trashing an engine. The few ounces of oil out of the catch-can go in the same container as the oil that was changed out, for proper disposal.
Will it void my factory warranty?
Good Question. The following is an answer from a Service Manager at a Harley Dealership-
NO... THE EBS WILL NOT VOID THE WARRANTY INSTALL OF AN AFTERMARKET TUNER WILL "BLOCK THE VIN" NO WHERE IN THE GLOBAL WARRANTY DOES IT STATE THAT ALTERING THE BREATHER SYSTEM WHILE LEAVING THE AIR CLEANER IN PLACE TRIGGERS A "VIN BLOCKING EVENT" THE ONLY THING THAT YOU MIGHT GET TAPPED FOR WOULD BE ALTERING AN EMMISSIONS CONTROL DEVICE IF PEOPLE ARE REACHING AND THEN....IT WOULD HAVE TO BE A LIVE PERSON TAKING THE TIME TO REPORT THE ALTERATION TO THE MOTOR COMPANY.
By installing your EBS on a 2020 Trike, does this void the warranty?
Only if you take your bike in for engine warranty work and the tech sees it and notes it. The digital tech cannot detect it.
I would use the EBS, and if I had to take it in for warranty work I would remove it and put it back stock. Only takes a few minutes to put it back to stock.
@@DKCustomProducts Thank you. Is there a video on installation?
@@bobgelder5086 We have a over half a dozen different options of EBS for a 2020 Trike, and we do have video of installation on some of them. I will link below the video installation of a premium discrete EBS on a 2019 Tri Glide....if you choose a different EBS than the premium discrete, let us know which one, we may have a video of it.

I beleve this is an issue with my ‘05 FLSTC. I have the SE 800 filter I can do the bracket with it, correct?

TKS.
Hey guys thanks for the explanation it explained alot. I'm in Canada and I'm looking for an external air cleaner. I own a 2021 Road Glide Special. Which EAC would you recommend I get?
The most power gain can be had from a 636v that you can see at this link- www.dkcustomproducts.com/outlaw-hiflow-636v-air-cleaner-system-harley-milwaukee-eight-dk-ac-636v-m8-cs.htm
Very close behind it is the 828, which you can see at this link- www.dkcustomproducts.com/milwaukee-eight-outlaw-hiflow-828-air-cleaner-complete-systems-40.htm
The 587 and 606 are both round style and very close in power gains to each other. You can see them at this link- www.dkcustomproducts.com/air-cleaner-intake-c10-315.htm
They all (except the 636v) have many different choices on covers for different looks.
Also, here is a link to a video that talks some about each of them. th-cam.com/video/xP7wxWQmSa8/w-d-xo.html
I have always used the Hayden vent, now I have the tank vent, plus I have your head breather kit, I don't see any problems with using both??
No, there is no conflict in using both the Hayden Vent and the External Breather System.
I now have a mad monkey VENTED dipstick and your head breather kit, will be using both on my M8.
@@hankhamern5456 Cool- the breather kit will keep the crap out of the engine. The vented dipstick will be there to hopefully take care of any temptation the bike might have to sump. We have a video planned where we will be installing some different vented dipsticks on an M8 (that does not have a sumping issue) along with one of our EBS kits. We will be testing how much air is vented via the EBS and how much via the VDS. Should be really interesting.
🏁
I get these guys know what they're talking about but God damn, listening to them gets my anxiety acting up..
Nothing to get anxious about. Thousands upon thousands run their bikes with no EBS and they don't breakdown or blow up. This is something to do that will extend engine life, and also give more power all thru that life. It's a nice mod that will save some $ in the long run and give a nice bump in performance.
fresh air and fuel only, my 16 RK runs so much better,
Good to hear! 👍
Just buy an Indian and forget all this nonsense.
They have exactly the same issue.
@@DKCustomProducts You're missing my point. Harley might not even exist in a few years.
They're selling bikes like hot cakes right now in my state. I've been looking for a Softail standard for a few months but they are all on hold and sold out right away. Meanwhile the local indian dealership closed down.
@@0100000101001100 It still does not mask this issue that Harley is in deep doo doo. Their first quarter sales for 2021 is only at 9%. That's hotcakes to you? Don't ever run a business pal, you'll run it into the ground with that philosophy.
@@0100000101001100 Yep, HD is shipping very few bikes to dealerships between now and the end of the year. They are having supply chain issues, just like so many other companies.
Companies like this thrive off of poorly designed bikes that have historical issues of poor performance, high maintenance costs and piss pour reliability. HD doesn't give a rats ass to build a better bike. To do so would costs money. A lot of money which they don't have. So, just slap together new parts of an old design, paint it shinny colors, then call it a new bike. Rinse & repeat. They've been doing this for decades and they're running out of time. Once the boomers die off (and they are) the new influx of young potential buys would rather buy a Tesla.
Thanks for the comment.
Lotta truth in your post, also seems like a lot of erroneous stereotypes.
Harleys are more powerful, more comfortable, more reliable than they have ever been. Check out the video linked below.
No doubt that companies that make parts for any vehicle, if they do them right, and provide good Customer Service, should do well. My guess is that Ford, Chevy, Honda have far more aftermarket parts available than Harley's.
