I'm 68, been riding since 1977. These two Gentlemen are awesome and their videos never waste your time. Thanks Guys!
Thank you for your kind words! Glad you are finding the videos useful/interesting. 👍
Thanks for the video. I just ordered a breather system from you guys and I am looking forward to installing it. My bike is a 2019 Street Glide Special. I ordered some extra black hose clamps to aide in keeping my blacked out theme. Great videos and I am a new subscriber. Keep the awesome videos coming. P.S. I went with a catch-can.
Glad you are digging the videos.
Thank you for your business, we appreciate it. I believe you will be well pleased with the Catch-Can EBS.
Thanks for the Sub.
Had the external filter on my Road Glide along with the 828 for 2 years now and love them both!
It is great to hear that you enjoying the benefits of having the 828 with EBS installed on your bike. Thank you for sharing and for commenting! MB
i have the Catch-Can on my 01Road King. On the bike for around 700 miles so far so good not much in the can yet just a lil oily but the carb is staying clean and its not going in my engine. just FYI when new the fins on my Catch-Can were very sharp and easily cut my hand when I tried to open it the first time. And it just looks awesome...
Glad you're liking it! Appreciate your business. 👍
I ran the hose to the chain and my rear wheel is well lubricated according to the dirt on it!
lol, yep!
@@DKCustomProducts yet the chain is grinding dry. I must re-route the hose closer to the road and forget the "too easy to be true" -trick!
Thank you for your Honesty.
Thanks for watching our vids and comment!
Just found this channel. Great content!
Thank you! Appreciate the comment, and good to hear you are enjoying the channel.
I’ve got the breather filter installed on my 03 Heritage Softail and it runs amazing with the fresh air,no more garbage being blown back into the throttle body,simple to do
So glad you are liking not only the products, but the benefits of them as well!!!!! Thanks for commenting!!!
Thanks for this video. I now have the external breather installed in my bike. I chose the filter. I drilled the holes and installed the brass hose connectors into my SE Chisel air cleaner. I routed the hose up over the throttle body, under the tank, and over to the plastic shelf behind the right side cover. The filter sits in a small rubber made bowl. After a few hundred miles, I inspected it and logged some more miles after adding some sea foam to the tank and spraying some B-12 throttle body and carb cleaner into the throttle body. It's very gratifying to find the air filter dry as bone without any oil contamination. I checked the Breather Filter again and it was wet with a bit of oil in the bowl. A quick clean up and she is good to go again. I may end up getting the catch can but it all depends on how well the filter set up works. So far I'm a happy Harley Rider. Thanks again
Glad you are liking the EBS and seeing the benefits of having one! Thank you for commenting!
You Two guys are awesome always great videos
Thanks so much, glad you find them useful! 👍
Back in the 70s used to run vent over to the drive chain, right where it came out of tranny. Dripped on the chain keep it lubed, relieving C.P. in the process.
Yep, remember those days well.
Helpful video, ive got a small 105cc big bored cub *yamaha townmate* and because the crankcase is still small 50cc at prolonged high revs it just pukes out oil everywhere all over the center stand so i ordered a oil cap with a breather hole to add a second pressure releif point so if that dont fix it the oil catch can it is.. 🙏
I do not know much about Yamahas but you should also make sure you are not over filling with oil.
thanks for your video. you both do a good job. do you have a video on how & where to hook up the hoses and what all i need. i have a 2002 softail. thanks much for any help
We have quite a few resources on that. Sort of depends on what kind of EBS you are using with your CC or Filter, but here are a few-

What kinda softail you got I have 02 FLSTF Fatboy
Running your filter set up hanging under my AC, while I like the concept it does throw alot if gunk down the side of my '09 UC. Thinking of ordering a catch can or just getting a 'T' & more hose & placing it under the frame.
Some of the older Twin Cam's do spit more than other bikes. You can check your oil level to make sure that you do not have too much oil in the bike, that can cause excessive spitting as well.
The catch can does a much better job containing the oil if you have a bike that spits a lot, or you can do like you said and route it under frame.

I did the filter option on my 07 Softy when I went to 110ci, clean it every oil change
That's great! I'm betting your engine likes that. Appreciate your business. 👍 Have you seen the little vid we made on cleaning the filter? ua-cam.com/video/be3R3KSmc4c/v-deo.html
DK parts are awesome and they work.
Thanks man. Glad to hear you're enjoying the parts. We appreciate your business.
Both, kind of... On my 98 Softail I run the breather bolt hoses to each end of a tee and from the middle leg I run that hose to another tee orientated so the side leg getting the hose from the breather nuts is horizontal. The inline ones on each end are now vertical, I run the bottom hose down to the bottom of the bike with a plug in it. The other end pointing up goes to a little filter. The bottom leg acts as a "catch can" and allows the air to go up and out the filter. My 91 FL is bottom breather EVO, that one I put a small actual catch can with a filter off that. She is getting older and the check valve in the pump will let about a tablespoon get by after a couple weeks. The can catches it all nice and neat, do not have that problem with the 98. The 74 ironhead is a whole different story...
I like you double hose set up. Nice. 👍
Could you do a video on an install on the hd heavy breather with a catch can for a twin cam
Don't know if a video of that will be in the works. We do not run HD Heavy Breathers, we run Outlaw 636V's, they are a forward facing design, but with a venturi component that makes them perform better than the HD HB's. However, if you click on the "Technical Info" button at the link below there is a pictorial of a step-by-step on how to do what you ask.

Thank you for this informative video. this answers many questions i had in my mind. just got myself a buell and planning to do the breather mod.
Congrats on your new to you Buell. It will like the EBS.
Thanks for the video. I just ordered a breather set from you guys and am looking forward to installing it. My bike is a 2013 Fatboy with about 13k km (so, only about 8k miles). I’m wondering if any carbon that may have built up might eventually burn off, or do you think I need to consider mechanical or chemical solutions? I don’t have any noticeable tuning issues at the moment.
Glad you're liking the videos, and we appreciate your business.
It will burn off. Periodic higher rpm runs (once fully warmed up) will help it burn off more quickly.
I do not use chemical solutions. They can be effective, and 99.5% of the time there is no problem with them...but that little chance that a big piece will break off and damage a valve or valve stem...that is not worth it to me.
Once in a while ride it like you stole it and the carbon will burn off
I have a catchcan with a breather filter on a bracket I made hanging on my road bar down in front of my oil cooler
Cool, appreciate your business, and I know your bike is thanking you for that.
Well done.
Thank you! 🏍
Thanks for your time guys, I appreciate your help and your products. On my 06 Flhpi with a tc88 , how do you add an external breather with a big sucker air cleaner? The backing plate has two slots for the factory breather hoses that sit under the air filter, when relocating the breather hoses from the factory breather bolts to the y connector it leaves the two channels empty to let un filtered air in to the throttle body. Basically it looks like I need to use some type of filler to close them off or is there a different backing plate that doesn't have the gaps ? I appreciate any help you can give? I have a 06 RK flhpi TC88 w/ Delphi injection I have the basic A. N. Big sucker kit . Am using factory breather bolts with the nipple on them and 1/4 hose routed behind the plate and over the frame. Haven't finished the install yet and haven't heard back from A. N. About it. Probably because they don't think you need an external breather with they're A.C. setup?
Most folks use high heat RTV or silicone to plug those holes. We have a step by step with photos of it in the "technical info" tab at this link- www.dkcustomproducts.com/diy-head-breather-system-touring-softail-dyna-sportster-dk-diy-bh-brt.htm
Some folks use set screws, as seen in this video- ua-cam.com/video/uAmPC_kglJk/v-deo.html
The other option is to get a different backplate, that will allow you to use the filter element and cover that you already have. You can see that at this link- www.dkcustomproducts.com/naked-hiflow-606-air-cleaner-back-plate-dyna-softail-touring-rushmore-w-no-filter-element.htm
First I just want to say you guys are the best when it comes to custom builds, more experience and knowledge than anyone else IMO and you share that with the world. My question is what are your opinions on running the hose near the chain? Would you suggest using a filter if my goal is to lubricate the chain?
I would be hesitant to use the blow-by to "oil" the chain. Depending on what bike you have it may spit enough oil or not. Then it is a matter of what it is spitting, some of it can be a really gummy mess. Take a look at the two linked photos below to see what typically comes out.
Also, most chains now days are sealed, and what little lubrication they need is specialized for the rubber seals.

@@DKCustomProducts makes sense but how about if I’m running the filter over the chain? As long as it’s cleaned during services I don’t see how the little bit of dirt on the filter would be much different than the normal dirt and debris the chain picks up from operation
@@exzackt No, getting dirt on the filter is not an issue. It will breathe as much as it needs to, although it should be cleaned periodically (depending on conditions, every 5000 miles or so. Here is a video on how easy it is to clean. ua-cam.com/video/be3R3KSmc4c/v-deo.html
@@DKCustomProducts ok thanks. Are you saying if I run the external filter over the chain, the filter will work to clean the blow-by of any of the nastiness that might be coming out of the blow-by? Would be a trick setup to put that wasted oil to good use
@@exzackt Yes, the filter would clean up a bit of the nastiness, but it might clean it up so much that not much oil would end up on the chain at all. If your bike is a pretty significant spitter, and it is mostly oil (not much water), then you might want to run just the hose if you want to use that oil on your chain.
hey fellas i just ordered a breather system for my 2014 low rider. i decided on the filter instead of the catch can. my question is if the filter starts to fill up with oil, will the oil come out eventually through the filter? or just build up in the filter? i prefer it just come out instead of building up in there. thank you for the great products. i had ordered a catch can for more road glide and loved it by the way.
How the oil builds up depends on a few things-
1. How much does your bike spit (every bike is different)
2. How long do you ride
3. How far away is the filter from the intake
The further it is away from the intake the faster it will build up. The closer it is, and the longer rides you take will have enough hot air reaching the filter element that it will vaporize and not build up as quickly.
Glad you are enjoying the parts, and we appreciate your business. 👍
I'm in favor of venting my trans top plate (DIY) , adding a check or pvc valve and a catch can to relieve the pressure/oil mist heading into the intake.
Yes, the dipstick or trans cover vent is a popular internet phenomena right now. We've seen no testing to validate the vacuum theory. We are going to be doing some testing soon. I don't believe you will damage your bike by doing it, but if you vent the head breathers in addition, you will be keeping the bike in better condition. Thanks for your comment. 👍
Thank You

I ride a 2018 Road King standard with the 107 M8. She has a stage 2 with a Fueling 465 cam, Bassani Road Rage exhaust and an Arlen Ness Big Sucker air intake. She’s a spitter! I suspected she was, so when I installed a DK external breather system half way through the summer, I installed it with 2 cans, hanging a can off of each cylinder out in the open just behind and below the air filter. They are out in the open easy to get at. I have to empty them every 600-800 miles. But I don’t mind because servicing the cans is a simple process. The crap that comes out of these is just amazing and I’m glad I’m not running it through the bike anymore. Why is she a spitter?......From an earlier video, I knew not to overfill the oil and I always run at or below the half way mark on the dipstick. I suspect the oil pump. She has an OEM pump that’s 1st or 2nd generation for the M8s. Harley is now on generation 4. To me, it’s just not worth it to put in a new pump because she’s never had a wet sumping issue where I’ve had a loss of power. In summary, I really like and recommend this product. Whether you buy the can or the filter depends on your installation. Mine’s right out in the open and the can looks good. If I did more of a hidden installation I probably consider the filter.
Yes, I would suspect the oil pump is the source of all that oil carry-over also...it sounds like it is not doing a good job of scavenging.
Really great to hear that the Catch-Cans are keeping it under control for you. We appreciate your business. 👍
Try a vented dip stick by Fueling or A1 Cycle it will solve your problems!
@@glencross4461 Yes, a vented dip stick will reduce the amount of oil in his EBS catch cans. Some of it will now be in the vented dip stick catch can, or along the bike if he uses a filter.
But it does not solve the problem of reducing the spitting, it just re-routes it.
@@DKCustomProducts yes it reroutes it so it’s not in your intake system anymore that’s a win for me! Happy New Year! 👍🇺🇸😎
@Glen Cross Happy New Year! Yeah, a vented dip stick re-routes Some of the hot, oily, oxygen depleted air, but not all of it. There is still performance robbing crap going into the intake, just not as much.
I have been running the catch can on my 2017 RGU for almost 15k miles.
Yes, I noticed a difference from day one.
Cool, we appreciate your business and thank you for commenting. Glad you are enjoying it!
I have an Arlen Ness big sucker that has the hoses going back into the air cleaner I don’t wish to change out the air cleaner all I want to do is redirect the oil into a catch can beneath the air cleaner what is your recommendations? My Arlen Ness big sucker is the large filter using the stock pier cleaner Cover.
Pull those hoses out of the back of the air cleaner, plug the holes in the back of the air cleaner. Route those hoses to a t-fitting and then to a filter or a catch-can. Feel free to text or email us some photos of your set up and we can direct you to what parts will get that done for you. 662-420-4891 or Support@DKCustomProducts.com

Good deal! 👍😎👍
I have a 2016 dyna switchback with the HO 103, I get some seepage from both breather bolts onto the cylinders, not alot but enough to annoy me. Will this system fix the leaking completely?
Yes, if it is installed per the included instructions it will not seep. Thanks for watching and the comment! 👍
I got 09 sportster 1200 custom i drilled 2 holes thru the air filter plate put 2 hoses to the vents thru the holes i drilled put a 3/8 TEE barley see my catch filter so far not one drip of oil mines right under the air filter
On the filter any sediments when you wash it won't it just keep building up, like sludge plugging it up or is it all liquid that it catches
When you spray the filter element with S100 or Dawn soap or Simple Green, or similar oil cutting cleanser, then let it sit for a few minutes, you can then spray it off and it will be clean, like new, INSIDE and Out. No build up.
Check out the video we made on how to clean the filter- ua-cam.com/video/be3R3KSmc4c/v-deo.html
I see from your pictures that on a 107 the catch can is attached next to the timer cover. What is it attached to ?
Not sure which photo you are referring to. However, both on the Twin Cam and M8, a popular placement is below the air cleaner above the timing cover, like in the link below. It is attached to the hose, nothing else. At first we thought it might move and bump into the pushrod tubes, but it doesn't. Hose is pretty short and stiff enough to keep it in place. If there is a different placement that you are asking about, let me know. www.dkcustomproducts.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/z/a/zammy_606_spoke_cc_ebs_3.jpg
Any downside to running the hoses up above the air cleaner instead of below? I want to route the hose to the other side and going up will be easier. Not sure if the sitting oil there will increase backpressure too much or if it doesnt make a difference.
Great question. The sitting oil does not increase backpressure/reduce performance at all. I run my hoses up and over on 2 of my bikes, and have been doing that for well over 75K miles on these two. Back 10+ years ago I ran them that way on my Sporty for years. The only situation where I would not do that is if the bike was ONLY used for short runs of less than 30 minutes and Never had any longer rides. Here's a link to a photo of one of my bikes where I'm running it up- www.dkcustomproducts.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/s/t/stealth_ebs_chrome_2_1.jpg
Here's a photo of a Customers bike where they ran it up and over to the other side to a Catch-Can - www.dkcustomproducts.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/s/t/stealth_breather_tc_2.jpg
Another brand had a recall. The crank vent hose had a low spot. Repeated short trips in cold weather could build up condensation. In freezing weather ice could block the crankcase vent, resulting in blown seal that could dump oil onto the rear tire. Recall routed the hose on a continual downhill, so water couldn’t fill in a low spot.
I used to commute on a Road King in the winter, as long as the roads were dry. I’d try to do a longer trip every week or two to let the engine get fully warm, but when I had occasion to take the breather system apart I was shocked at how much water there was…

Question when you add any kind of filter
Will that not create a back pressure especially when the filter get slightly
Plugged
It does not cause any problem. I suppose if it was caked with dried mud it could plug up enough to be a problem. I've run mine for well over 10K miles without cleaning and it has never plugged up enough to be an issue.

Can this type of modification be done on a 2021 Honda CB500F? I just got the bike recently, pretty much brand new.
It looks like there is a breather hose with a plug + clamp on the left side of the bike (which I’m assuming works like a catch can), but I don’t know if the bike is designed to recycle the oily hot blow-by gas back into the intake, or dispose of it into the tube.
While we don't know anything specific to your Honda. All engines sold in the USA, including Honda's, must push that hot, oily, oxygen depleted air back into the intake. Hopefully you can identify the route taken to do that and push it into a filter or catch-can.
I have a 2014 Road King CVO after watching this video, I removed my Screaming Eagle air cleaner. It was full of oil. After looking closely at the engine breather bolts I'm not sure how it can be modified. The back plane has angled holes that lead to black spacer around my bolts to the heads. Can I replace my mounting hardware or drill a hole into them from the bottom and attach a hose, then tap and plug the back plane holes? Is there a kit for the CVO Screaming Eagle air cleaner?

Two questions: What happens if the catch can fills and doesn't get emptied? Is their "noticeable/measurable" power change after installing either the catch can or filter?
Great questions, thanks for asking.
1. If the can fills up (rare) then oil will start seeping out the vent holes on the top. It will continue functioning as it should.
2. Most folks do notice an increase in power. (but not everyone...I believe it depends on how you ride and how well you know your bike)
It is measurable, you can see the dyno chart linked below. Here are a couple of comments from Customers.
"Ordered the breather system for my wife's Twin Cam Freewheeler and my Heritage Classic 114 Milwaukee 8. Easy installation instructions and high quality components. The performance on both bikes have improved and they are running cooler in the warm FL WX. Highly recommend you install the breather system(s) on your Harley. You will not regret it! Thank you! (Posted on 5/17/2021)"
"The first thing I noticed was my engine was running cooler! Maybe I’m just imagining things, but I seem to have more power."
"Install was easy, all parts needed were there. I noticed a little more get up and go when I hit the throttle, even the ol'lady noticed it. I ordered the braided line with it, looks great. Thanks DK. (Posted on 3/1/2021)"

Great video. Thanks for sharing.
Great to read that you enjoyed! Thanks for the comment.
Good video is it bad to see small amounts of white smoke come out of the filter while starting sometimes more when hot
Thanks, glad you enjoyed.
Th white smoke is the water burning off, it is normal and nothing bad about it.
Should I vent my dipstick as well as at the air cleaner? Or do I just need to vent at one location?
Great question. Venting the dipstick only stops some of the hot oily oxygen depleted air from going into your combustion chambers...Not all of it. The External Breather System stops ALL that crap from going in. A vented dipstick is trying to relieve the same crankcase pressure as the EBS, so no need to do both.
There is one exception...if you have a weak oil pump that is not scavenging well, or have a very high compression ratio resulting in excessive CCP, then doing both can reduce the possibility of sumping.
Awesome thank you for confirming my thoughts. Can’t wait for my 4 stage system to come!

Here is my deal on my 21 street bob 114. I bought an aftermarket breather off of eBay. It is one that has the glass see through cover. There is no external breather. Instead the kit just caps it off completely. Is that bad? I did notice after only 10 miles of riding. The glass was covered in moisture. Water. Is it good to have the system blocked off like that?
The air cleaner may look like it is capped off at the breathers. It is Not. It is feeding that hot, oily, oxygen depleted air into the air cleaner, and part of that is what you are seeing on the see through cover.
This is a very useful video on the subject to watch- ua-cam.com/video/EfDeFZblMck/v-deo.html
Just so you know, if it were blocked off you would have oil leaking out of various gaskets on the engine.
For the longevity of your engine it will definitely last longer if you are externally venting to allow all that hot, oily, oxygen depleted air out of the bike, rather than trapping it in and causing more carbon build up.
We have a variety of External Breather Systems that you can see at this link- www.dkcustomproducts.com/all-twin-cam-engines-c76-323.htm

I love and want the black catch can breather kit, but the shipping cost of 71 to Netherlands is crazy.
That does not seem right...but who knows what the postal services are doing right now during the pandemic. BUT, if you will write Support@DKCustomProducts.com with what you want, and your address, they can check and see if there is a better price than that...hopefully it is a lot lower than that.
@@DKCustomProducts yeah same to australia nearlly the same as the catch can just for postage " thats so wrong
@@damienfrigo4734 Yeah, shipping costs from the carriers just keeps climbing.
Write Support@DKCustomProducts.com to see if there is anything less expensive.
The other thing is that usually a larger package is not that much more expensive than a small one. Getting multiple parts at a time for yourself (or a group buy) will lower the cost of shipping per item quite a bit.
Got one for sale in the Netherlands if still interested
is it needed for a 2021 road glide special? 2021 and above have a difference oil pump.
Yes, all engine produce crankcase pressure, which results in hot, oily, oxygen depleted air going into the combustion chambers. This results in less power, and carbon buildup in the throttle body sensors and pistons.
The newer oil pump was to fix the sumping issue, but it does not eliminate blow-by which is the power robber.
Every bike has different levels of oil contained in the blow-by, and an oil pump can have some effect of making more or less oil being suspended in the blow-by.

I am a new 2021 HD Sportster owner, and do not want to replace the factory air cleaner at this time...but want to put this external breather on. Can it be done?

Okay thanks ! 👍
I used an old aluminum fuel filter and changed out the filter element with a small piece of sponge inside. Sponge soaks up most of the oily crap.
Very cool. We played around with modifying some fuel filters. Still have a couple sitting on the shelf. Is yours clear...I like the idea of seeing inside it thru the clear housing. How are you venting it?
@@DKCustomProducts No it's not clear. It was a one I had left laying around from a chopper build. I just connected on the end underneath the bike. Left the end open, so it goes through the sponge and out the other end.

I put a small inline clear fuel filter on mine. It's hidden under the trike. Seems to work perfectly.
Hi DK, I have a 2019 Street Glide with the SE 128ci stage 4 kit installed. They installed the new HD oil pump and since then, the bike burns oil (can smell it from time to time) and the filter/intake has oil inside. Even the spark plugs are dirty. She runs hot 🔥 320 to 340°F. Had to refill oil twice now in less than 2000 miles.
I have the Trask Checkmate installed.
I will install the Feuling oil pump and cam plate as soon as Michigan warms up a little, if the runout is good.
Do you think, that a EBS will help with my issue? Or do you have an idea 💡 what could cause such an issue? Thank you in advance!!!
There are two things that I would look at.
1. They may have made a mistake in the installation of the Stage IV kit...we seen that happen. Have them do a Leak-Down test as a first step to tracking down the problem.
2. Whether it passes or fails the leak down test (should be at least 95% or higher), it is running far too hot for its' own good. Check out this video series (if you don't watch them all, for sure watch #3 in the series) ua-cam.com/play/PLb3bvZgbH92_3s-2vv63QggFJ3nteFd_C.html
Yes, an External Breather System will help the bike run stronger and last longer, but it is not the entire solution to the heat or the burning oil.
@@DKCustomProducts I just made a leak down test myself and found the rear cylinder is good with 97.5%. The front cylinder is at 25% with air coming out of the intake. I made the test 3 times on the front cylinder to confirm it. Now I am waiting on the service manager from my HD dealer to call me back.
@@ellomred7713 Bummer. But glad you found out what the issue is. Hopefully they will be stand-up and take care of you.
Thank you for getting back to us with what it was.

@@DKCustomProducts I will let you know. Thank you for your input on the issue, it is highly appreciated.
Just installed the Flo reusable filter and your relocation kit. I have the Jim’s cooling fan and your 1“ tanklift sitting here to get it installed as well to cool the motor down.
@DKCustomProducts got a call today from the dealer and they weren’t able to produce any leak down on the motor. They stated, that they were able to get pressure by rotating the motor in the push rods. They asked which oil I am running and blamed the Amsoil 20-50 syn. I changed now over to redline 20-50 syn. Let’s see how that will work. They want me to monitor the oil every 1k miles, if it’s less than a quart it’s good by HD.
I will proceed with my Feuling cam, cam plate and oil pump change, to see what happens. Other mods in the pipeline: Jim‘s force flow fan, tank lift deluxe, A1 oil pressure gauge, tab performance headers, dynojet target tune, S&S roller rocker arms and maybe the Ultracool oil cooler with fans. I already have the dkcustom deflector wings at the front and a Jesse oil temp gauge.
I am still trying to figure out if I should go with a catch can, but it has to be reversible because of the German TÜV inspection guys.
I used an in out catch can, filter on out side. What do you guys think of trask check m8
Vented dipsticks and transmission cover vents do NOT take the place of external breather systems.
There is still hot, oily, oxygen depleted air being fed into the intake.
The folks that sell vented dipsticks and trans cover vents, have it right in their product description that they do not prevent all that crap from going into your intake.
Here is a copy and paste from the Trask website- "This will reduce the oil exiting from the head breathers..."
Even if there is no trace of oil in the intake, there is still hot, oxygen depleted air going into the combustion chambers, making the engine run hotter, and not as strong because of the lower oxygen content.
IF you have an older M8, with the older oil pump and you are concerned about sumping...OR, IF you have a built engine with higher compression, then it may be beneficial to do an EBS And a vented dipstick or trans cover vent.
@@DKCustomProducts thank you
What about heavy breather system and vacuum? How do you do this and keep it in a vacuum state that’s needed?
Your question presumes that a greater vacuum is needed than naturally occurs in the crankcase.
I have seen the recent popular thoughts on this subject, however, not a single person or company has provided any test results, or data at all that there is any validity to their theory.
What is known, and what there is a plethora of testing and data on, DO NOT put hot, oily, oxygen depleted air into your intake. It will reduce power, cause accelerated wear, and result in tune instability.
These things are all well documented.

Also does that and heavy breather also help with heat problems?
@@Heavy69Metal What you may have seen is a vent on the top of the transmission.
These vents, and the oil tank vents are changing the crankcase pressure.
They were initially designed as a bandaid for sumping problems on the M8.
If there is a sumping problem, it should be addressed at it's root cause. If there is not time or money to do that, then folks have used those vents to bandaid the problem until it can be fixed.
The Harley Heavy Breather, unless modded with an EBS is like any other mediocre aftermarket air cleaner. The 636v, with the patent pending design, outperforms (and out cools) the HB, for those that like that style of A/C.

@@DKCustomProducts what is prob cause of the sumping problem? The Oil pump? And will that cause over heating as well?
@@Heavy69Metal Oil pump is not scavenging all of the oil out of the bottom of the crank. Not saying there are not some inherent designs in the M8 that make it more likely to sump.
BUT, you hear of VERY few 19+ bikes sumping...HD finally hit on an oil pump that scavenges better.
Yes, sumping will result in the engine being hotter...but that is the least of the symptoms. It will feel really doggy as the crank works it way thru the oil.

The ONLY leak on the whole bike! Made sense. I cut 1/2 of the curve at a slant. Then what would be better is a bit of screen shaped then a tiny hose clamp since its there for a small bit of breathing/balance. Better would be after adjusting the cable, (get this) and cleaning the adjustment/cable shaft sealing it with Black Gorilla tape (it comes in duct tape type rolls so strong it's exceedingly hard to even get it Off the roll!!

mount your filters above your source and this will minimize the oil output. the vapor will escape as wanted and the majority of oil will run back down hose. the engine intake breather i just vent to the ground below frame with open hose. but i have very little blow-by. some of these aftermarket parts companys are making big $$$ on manufacturing venting parts, aka dipsticks and tranny plates. it's way easier than that. do your research. lots of info out there.

What about breather bolts? I have some from Lowbrow Customs and TC Bros that I've never had a problem with.
Yes, we have had the Outlaw Breather Bolts available for over 10 years now (LBC & TCB complimented us by copying the idea). They work well on 99% of Sportsters, about 50% of Twin Cams, and about 80% of M8's. The filter in them is really small, so on a bike that is a spitter (has a lot of oil carry-over) they can overwhelm those small filters and get oil along the side of the bike. Good to hear you don't have a spitter. 👍 More info on them at these two links- www.dkcustomproducts.com/external-breather-system-breather-bolts-336.htm AND www.dkcustomproducts.com/external-breather-system-breather-bolts-328.htm

Filter thanks
Thanks for the advice I was leaking oil did not know it was designed this way first harley 08 touring classic going to ad a external with a filter
How about the HPi alternative heavy breather
We have not tested them, but they look like they should work well. They are relatively new at offering External Breather Systems...and from what I see -
"Purpose built to retro fit other select air cleaner kits that use a flat mounting back plate."
Appears after spending $90, still need to purchase T's and filter or catch-can.
How will the filter do on rainy days?
Your Crankcase ventilation system only produces positive pressure. Additionally there are breather valves in the heads just beyond the breather bolts. Think of those valves as a check valve that would make it virtually impossible for any liquid, including rain water, to compromise the crank case or engine oil.
I purchased a filter and placed it above the air cleaner. My only complaint is that I smell the oil now. I'm thinking about removing and replacing it with a can.
For Gearheads....the sweet smell of oil, gas and burning rubber! 😃 If you want to get that smell away from you, there are many places you can locate the filter element. Look at this photo for one idea- www.dkcustomproducts.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/b/r/breather1_1.jpg
Is there anyone that has info on the idea that the original
configuration needs to be under vacume? And useing the breather config makes a free breathing type issue.. dunno? Just askin.
Engines have been running with External Breather Systems for over 100 years. Running an EBS is only going to help your engine run better.
There is no measurable change in crankcase pressure on the original configuration when running and EBS.
I put external breather bolts on my 2002 Fatboy barely anything comes out. Maybe a little get on the side of the bike.
Good deal, we appreciate your business, and glad you are enjoying the benefits. 👍
I have had mine vented for years with custom tubing and fittings from jegs. Mine doesn't spray or mist out any oil any more at all really.
Thanks for sharing 👍
Mine either. It used to. I have a custom setup of jegs tubing. It looks sick with red and blue fittings and chrome angled piping. I get nothing anymore though...?
If i run the hoses up and over the engine instead of down, will the oil collect in the hoses and hinder the breathing of the engine?
No, it is all positive pressure that is pushing through the hoses. It can help if you are having a lot of condensation due to shorter rides and the engine not fully warming up.

Which is better a breather system or a vented dip stick other than price?
Well, as you alluded to, the vented dipstick in MUCH more expensive...but what really is ironic is that vented dip stick does not eliminate the Hot, OIly, Oxygen depleted air from going into the combustion chambers, which is a power robber and a longevity issue. Yes, it does reduce it some, but since it does not eliminate it...it is really only something to look at if you have a sumping issue. And if I had a sumping issue I would resolve it at it's source, not put a bandaid on it.
The other reason is if one has a built engine, that for some reason is building excessive Crankcase pressure, that would be a reason to have both a dip stick vent and an EBS.

Vented transmission cover to relieve pressure and lessen the amount that will make it to the intake in the first place…. Seems like we all should be doing both
Why? Vented Trans still send hot, oily, oxygen depleted air to the intake, so an External Breather System is needed.
If you have an EBS there is 100% of pressure relieved, there is no hot, oily, oxygen depleted air going into the intake, so where is the need for a vented transmission?
btw, the only reason for the dipstick vent or trans vent was because of the bad oil pumps the first few years of the M8. That has been resolved...and if one has an early model M8, it is highly recommended to get the latest oil pump, which alleviates the extra pressure in the crank.
The only time that it makes sense to run a vented dipstick or trans vent, in addition to an EBS, is if one has a highly built M8 with a very aggressive cam, and/or really high compression...reason is that more than the normal amount of pressure will push past the rings into the crank, building excessive pressure.
That said, I know a few guys with built 131's, running an EBS, and running them cool, and they have had zero issues.
@@DKCustomProducts are you certain? That the EBS relieves crack case pressure ? How? It seems to me that the EBS relieves the symptoms, but not the cause.. but you are right it’s for higher built motors. I’m running a woods 22xe on a lowrider st .. so I’m thinking from that reference point
@@drainmonkeys385 That is exactly what the breather bolts do, relieve crankcase pressure. If there were no crankcase pressure, there would be no need for breather bolts.

Thank you for your business, we appreciate it, and I believe you will be well pleased with the External Breather System. 👍
Glad you got it rebuilt...sorry that happened. Even though he said he does not know why the engine grenaded, it is almost assuredly either from heat or from sumping, or both.
Here is a Report that you may find useful/interesting- www.dkcustomproducts.com/why-how-to-cool-down-the-twin-cam-engine-part-i-dk-cl-tc-dn-1.htm

how much will the catch can hold?
More than most bikes spit between oil changes, about 1 ounce, which is more than 99% of the Harley's out there spit between oil changes. We recommend emptying it at every oil change. We do have Customers that have serious oil spitting issues that have to empty the can every 1-2 thousand miles.

Don't just run a hose! The oily deposit will attract dirt.....My situation: I put a catch can with a filter on, connected to my head breather hose, and clamped it to the left (primary) side front riser of my frame....Okay. When I checked/drained the can after a few hundred miles, there was a good amount of what looked like water, not oil, in the can. I collected it in a container, luckily. But I think this is from heated air that cooled and condensed. Anybody's thoughts?
Condensation is found in the catch can when the weather is cool/cold and/or when there have been a lot of short runs...where the engine did not get to full operating temperature and stay there for a while.
This is because water is a by-product of combustion AND because of the heating and cooling cycles which result in condensation.
When an engine is fully warmed up and runs for 15 minutes or more at full temp, all the water is expelled as steam....otherwise, it collects in the catch-can.
@@DKCustomProducts Thanks for the reply. I appreciate it. My bike is run for a half hour at least because of where I live, and takes a while to warm up. So, yeah, that makes sense. Thanks again.

I use the tiny filter on my TDI. Lol
Just common sense! 😂
Why not a vented dip stick ??
While it will reduce the hot, oily, oxygen depleted air going into the cylinders, it does not eliminate it. So, why spend more money to do half the job?
i would vent my pan & shovel wt a filter, never considered my twin-cam, tks.
It really does help...on the M8's too.
Thanks for your comment.

I have a HD SE air intake and DK Customs External Breather with Catch Can. The earlier version of your catch can. What’s the improvements with your new version?
If you do not have a real spitter (the oil is not overwhelming your smaller catch-can) then you do not need the newer one. The newer one is larger, so it can hold more between needing to empty it. The newer one is a 4 Stage filtration inside the can. The improved filtration does a MUCH BETTER job at keeping all the oil in the can...this is really important for bikes that have a lot of oil carry-over.
You can see in the photo below that the filtration is made up of 8 individual components, designed to let the air out and keep the oil in. The Catch-Can you have now has just one piece of foam in it.

@@DKCustomProducts thanks. I lost the old foam and replaced it with the breather foam (cut to size) from a b&s lawnmower. It doesn’t seem to capture the oil like the original foam filter. Can that filter setup for the new can be used in the older can.
It’s not a big deal. I just had to clean it more often this summer.
@@h3r63rt You may be able to make it work. Never thought of it, nor did we try. You can see the replacement kit at the link below. You would definitely need to cut it a bit, and not use all 8 pieces, but it seems like it could be adapted and work very well. www.dkcustomproducts.com/4-stage-black-catch-can-for-external-breather-system-ebs-harley-2095.htm
Catch can looks sharp.
Thanks! And the Machine Cut one IS sharp! Those fins have cut more than a few fingers when working with it. :)
Catch can hose n clamps why you charge so much?
The catch can is a big part of the cost!

Does an EBS void any warranties?
Only if they see it. Per the Federal Law of the Consumer protection act it does not, BUT Harley and the EPA entered into an illegal agreement so that on 2017+ Harley's, any change to the engine voids the powertrain warranty.
Rather than fight their illegal collusion, if you ever need to take the bike in for warranty work, it is easy to remove the EBS and put it back to stock. Takes about 15 minutes.
That way you can run what you want to on your bike and not have any issues.
