How to Vent Any Harley Air Cleaner To Run Stronger

[@aaroncox3340]

I've got a round extreme flow screaming Eagle air filter etc, the one you said can't be done. I did it, all you have to do is cut both sides of the venting hose and place in a small barb fitting on both sides, with T section barb, drill your hole on the backing plate, run the hose out, all done, took me 10min. Checked it a dozen times, everything working well. We're there's a will, there's a way.

[@DKCustomProducts]

I would love to see some pictures of how you done this. It is certainly not one we have modified to be equipped with an EBS. If you do not mind send us some pictures; [e-mail] Thanks for commenting! MB

Awesome Thank you! 😎

[@Tryke_Ryder]

I installed the transformer and the 828 filter and catch can, and it’s awesome! I was upset because it didn’t come with the longer bolts for the black finned cover, but when I pulled the K&N filter box out of the shipping box, the bolts fell on the floor and I kicked it under the bench. Took me a while to find it again. PS: the customer support is awesome!!!

Glad you are well pleased the parts and that you found your bolts! Thank you for your business and for commenting! MB

Lol, the same thing happened to me. I was working at night in a dark garage. Thought I installed it wrong. Went back in the next day and found the bolts 😂

I had a hose type EBS from DK for a while. Had it leak once and it looked cluttered to me so I converted to the Transformer back plate with a HiFlow 828 air cleaner a catch can hanging underneath the setup. Very clean looking and no problems what so ever. Great design.

Just installed my 828 contrast finned with external breather filter, bassani 2x2 header, 3.5 no baffle mufflers with the 158 torque converters. I called you guys because I was worried that the torque converters were too small. You basically said that they'd do the job but may be loud and backfire. Anyways. I'm damn happy. the breather looks great, and the bike sounds perfect for me. Tuning this weekend. Thanks for the great videos, and products.

[@scottwheaton9689]

One thing to add here that’s over looked is for bikes that have got some miles on them before adding the EBS that already have significant carbon buildup in the combustion chambers from ingesting hot oil laden blowby crankcase gases for 25k-50k mikes that need to be decarboned without taking the motor apart. What can reduce carbon buildup is to run a healthy dose (1.5-1.75oz per gal fuel) of Chevron’s Techron injector/combustion chamber cleaner in a black plastic bottle that says Concentrated on the label. Keep in mind if there’s mikes in the motor with carbon buildup you will have to run quotes a few tanks of fuel (4-6) treated with Techron dosed as rec above to remove the excessive carbon buildup already in comb chambers on valves pistons etc. It won’t hurt anything to run mult doses of Techron which is also a good thing to run thru the motor & injectors 2-3x yrly in s tank of fuel just prior to an oil & filter change. But also keep in mind when you run mult tanks treated with Techron to remove excess carbon it can possibly contaminate the motor with so me sml carbon particles removed from the comb chambers so change the oil right after your done doing the mult tanks of fuel excessive carbon cleanup. Another way to quickly remove carbon is to use Seafoam intake application hose you can insert into an aid cleaner/filter system with motor running to fog it heavy & then let it sit while it’s hot for their rec amount of time. Then you retire the motor & run it till it burns the remaining Seafoam & loosened carbon out of the motor,it makes a Smokey mess which i rev doing just prior to an oil change too.mI font rec the old school dripping cold water into the intake with motor running to remove carbon like old timers did to motors in 40’s thru mid 70’s that literally shocks/hammers the carbon off pistons,YIKES!😵‍💫😵‍💫😵‍💫 Happy motoring.

[@chuckbrewington6817]

Been running thru your EBS with one of your air cleaners as well as a S&S teardrop on my 09 RoadKing. It's been great. My tune has held. I do empty my catch can a little more often as I catch shorter rides in the cold and wet but in the summer time on long runs I get longer time intervals. Damn. I need to order the catch can guts.

[@DKCustomProducts]

Glad you are well pleased with the Air Cleaner and EBS! Yes you can certainly go longer intervals before cleaning out the catch can when your bike is getting fully warmed up to burn off some of that oil and condensation! Thank you for your business and for commenting! MB

[@jasonsgrowingtree5764]

I have your guys kit and it’s awesome but I’m wondering about if an air cleaner cover restricts air into the breather.

[@DKCustomProducts]

Glad you are well pleased with the EBS. It really depends on the cover. If it is a hard shell then yes it will be restricting the air flow, we call those HOT BOXES. If it is open around the filter it will not be restrictive. Just make sure that any cover you are getting allows Air through the filter. Thanks for commenting! 😎 MB

What kind of damage is done to the engine/parts from not having external breather from the factory? I’ve got 25k miles on my 117 with no external catch can

[@DKCustomProducts]

Since the engine only burns gasoline and oxygen, that oil ends up as crusty carbon deposits on the pistons and valves. Periodically, little pieces of this carbon break off and scrapes the cylinder walls or gets stuck between the valves and the valve seats, both of which prematurely wear the engine. You can see at the link below if you scroll down to the pictures that there is a huge difference in the carbon build up on the piston. The first picture was from 5000 miles of riding without an External Breather System and the third picture is the same exact piston after 27,000 miles of riding with an External Breather System. - www.dkcustomproducts.com/overview-of-external-breather-systems-ebs.htm Here's a video you may find interesting/useful- kzbin.info/www/bejne/e5enlnmQl9GAmc0 Thanks for commenting!

What's your opinion about the Feuling external breather system? It's quite a bit more expensive than DK's and I know you don't sell it but what are your thoughts about it? Just curious.

[@DKCustomProducts]

It looks like it is a decent system. The only down side that I see is that it only fits their backplate. So it would be a good system if you already have their Air Cleaner, but if you have a different Air Cleaner that you are looking for an EBS for you can see all the EBS systems we offer here - www.dkcustomproducts.com/breather-systems-c21.htm Here is a link to the report on how to choose the right EBS for your set up - www.dkcustomproducts.com/getting-the-right-external-breather-systems-ebs-for-your-bike.htm Thank you for commenting!

Why does my catch can fill up with water? 2023 sg st 117

[@DKCustomProducts]

It could be condensation if you take a lot of short rides and your bike does not fully warm up. We suggest you allow your bike to fully warm up to burn off a lot of that condensation. If you can not let your bike fully warm up every time you ride you can cut a piece of shop towel and place it in the bottom of the catch can and it will help absorb some the condensation and hopefully keep it from spitting out of the holes. The filters that are in the catch can are good at holding oil but not water substance. So the shop towel will help with that. Routing your hose with the catch can up and over the heads will allow the condensation longer to burn off before going into the catch can and over filling it. Here is a video about that that you may find helpful at the 5:40 minute mark it talks about rerouting your EBS - kzbin.info/www/bejne/jnrCd6CpnqyVeK8 Please let me know if you need anything else.

Up and over has caused issues for 2 different routing for me. Hoses all clogged with yogurt style gunk. My 3rd attempt is directly under the air cleaner. Think the shortest distance is the best

[@DKCustomProducts]

I hate that you are having issues! Have you checked your oil level? Do you go on a lot of short rides? What kind of oil do you use? What bike do you have? We have had very few problems with people having too much condensation or oil carry over that were solved with changing brand of oil and allowing their bike to fully warm up when they ride it.

[@kevindelk]

Hey guys, I have a 23 street glide. Had the syn3 until my 5k yesterday. Now have redline 20w50 . I run my oil at the halfway mark on the dipstick. I never go on short rides. Always 30 miles minimum. Use my vulcan for short rides. I give the bike about 3 minutes to warm up. I do ride year round and temps only get down to the low 30s. I did have the 2020 heritage m8 with the catch can from you guys and it would get the water and gunk inside, but the line never got clogged with weekly empties( mostly water). Moved it over the the 23 with can and it plus hoses got clogged really soon, so switched to a pod filter. Hoses still got clogged but filter was cleaned. So now I have the pod filter directly under the air cleaner. The hoses run directly through the backing plate and down to the pod like I originally wanted it as u guys also suggested. Just needed a different size barb so the pod is connected to that and not a short connecting hose. Which now makes it work on the new m8s with that smaller area. So now time will tell on how my 3rd attempt works. Also, on my 2020 heritage I ran redline 20w50.

[@johnhammered3321]

Why do dealers claim that if you by pass the breather bolt into a catch can it may void your warranty? They claim that the oil being squirted in your injection port helps lubricate the cylinder walls! I beg to differ with them because it gets burnt in the combustion cycle. And there are already points where oil makes it way to the pistons and cylinders. This malarkey may be true in commiecalifornia where they have to play the EPA game, but here in Florida, land of the free, we could care less about how noisy or polluting our bikes are!😁👍✌️🇺🇸

[@DKCustomProducts]

Not all Dealerships say that, but those that do, obviously do not know what they are talking about, and lack a basic understanding in how an internal combustion engine works. Sad, but unfortunately the ignorance at Dealerships seems to be on the rise. Oh, and regarding the warranty, if one has a Dealership that they feel they need to use that is of this mindset, just remove the EBS prior to taking it in for warranty work. KP
