Interesting, I have read the same info on the external breather, but you explained it very well. I will look into this over the winter as I have my bike sitting for about 5 months. Thanks!
I actually just completed the same mod on my 2014 110" Slim. I ordered the same aluminum brake reservoir (in Black) with the bracket. I drilled several small vent holes on the top and used it as the catch can. I mounted it using one of the cam cover bolts. Looks and works great! Thanks for posting the great video! Cheers from Washington state, USA!
Now that's my kind of video ! Perfectly clear and straight to the point . I'm going to do the mod on a Sportster . I had planned to put the T piece inside the filter but if it's outside there's no danger of anything getting sucked down the carb . Great stuff .
I can absolutely confirm that the carbon build up is happening. I went to a stage three and the carbon build up on the pistons was terrible. I also got the new metal throttle manifold and I inspected the old black plastic throttle manifold and it had a thick grime coating of oil. So this mod is a must along with ensuring you don’t over fill your oil (two dots below full). Thanks for this video!
Thanks for the comment Russ, I expected the carbon build up in the m8s but you have just confirmed it. How many kms did your bike have when you noticed the excessive carbon build up?
@@jstockwell73 It is, people are making a big deal out of nothing, the oil "issue" is not an issue at all, there are M8s with 30k miles on them, they run fine, just use some engine cleaner, save yourself some money and don't make your motorcycle look like you built it yourself in your garage by having tubes hang off it like a Kawasaki. If it was as big of an issue as these people are making it out to be, you would have to dump a quart of oil in it between oil changes, the fact is, the oil doesn't get low between oil changes, they are emptying that tiny can out every few thousand miles and probably do not need to for 10000 miles. That amount of oil being burned at that slow of a pace is nothing.
Dude your attention to detail is astounding i love it. This is the type of channel i love to watch. Never half assing anything. Just purchased the same bike and i will be doing several of the mods you have on your bike. Keep up the awesome content i love it. From arizona in the USA. THANKS
So got my DK catch can and running the same setup as you ' have done roughly 70 klms so far and opened it up the next day , and found 1/3 of the can with water in it but no oil so something is working .great set up cheers
The water is caused by condensation from the heat in the catch can. You will notice a small amount of oil mixed in with the water over time. I ditched my catch can and went back to a pod filter after the thread in my catch can began to rust
Great video! I realize this is an old post, but want to say this is the most clear, easy to understand, diy video about external breather modifications that I’ve seen. Liked and subscribed!
Just learned something this morning Great vids btw!! If your oil level is correct & engine is NOT sumping.. this mod should never be required with proper crankcase ventilation
@@TheGingybeardMan www.a1cycles.net/new-products/2007-up-screw-in-ventilator-cap-wrinkle-black-finish This is much cheaper but doesn’t have dipstick. I use it. You can feel the difference it frees up hp.
@@TheGingybeardMan they will not work on the M8 models, I make them myself by altering the oem dipsticks, can show you pix if you like. Could you give me the part n° from the airfilter and cover please.
Guys, this is a great idea. But keep in mind that the original problem was oil sumping. So the ability for this line to breathe is important. The catch can should have a line for fluid and a pod filter to vent gasses out at the top. If you connect the hose to a closed catch can the pressure has nowhere to go, so the pressure from gases will not move, bringing the engine back its original problem to begin with. External breather kits like the one sold by horsepower ink flows to atmosphere. It is more like a hydraulic remedy. Of course, without a breather cap hydraulic pressure cannot move. Just something to keep in mind. ✌
After using a catch can for only 1500 kms I certainly would not recommend one. As you said it can pressurise. I'd definitely recommend a pod filter over a catch can. The catch can also began to rust significantly on the inside after only 1500 kms
Yes! Thank you. I have Sporty with a stage 1 AC of the same style and am wanting to go a breather bypass of that exact same method, but unsure if it would work. Brilliant!
I don't know about your bike but I noticed the difference in performance as soon as I put my external breather on..mostly because the air fuel mixture wasn't hot anymore..Also if you keep your oil level around half way on the dipstick (when hot of course) you really won't get much oil in that catch can..I just kept a pod filter on mine mostly just to let the hot air out.. Mines a twin Cam though, but still shouldn't be too much different than the m8 with the amount you'll find in that filter..My set up cost around $15 using 10mm fuel line, a couple of connectors and a $4 eBay filter.. Great little mod that's easy to do for longevity of your motor I reacon..Keen to see what your bike looks like with the bigger tank👍 Keep the vids coming mate!!
Thanks mate, you're right it can be a cheap little mod or a little more expensive if you buy a DK customs catch cans. I believe with including the cost of postage the DK catch can was around $80 Au. Other than the cost of the catch can it would have been a dirt cheap mod 👍
My friend, you make some awesome content - really like your editing style. But moreover, I love your attention to detail; exactly how I am with my bike. The breather I’m putting together for my ‘21 low rider s will be exactly like yours (aside from I’ll vent to atmosphere or filter). Of all the ones I’ve seen, it’s the best. Your street bob is a beast, Ride on brother 🤘🏻
What you failed to mention is to use that filter oil as sparingly as possible 😆 I used the stuff on a heavy breather just like you did and the amount of excess oil after significantly blotting it for ages was still significant enough to drip on the cases. With the K&N filter for the ventilator all I did was run one ring all the way around the filter and leave it for 24 hours. it still required several days of blotting with paper towels. Can imagine your clean up was well excessive 😂
Nice presentation, you are a good presenter and nice video shots. HOWEVER, please give credit to those who produced the photos. The professional thing to do IMHO
Im going to do same mod but put t piece inside air cleaner housing so only need to drill the 1 hole an only 1 hose coming out of air cleaner. Good work.
Only reason I didn't do that was because I did not want the t connector coming loose inside the intake as it'll go straight into your engine. For piece of mind I rather have the t connector on the outside 👍
Looks real nice! I can't wait to see it when you you get the bigger tank on. Are you going with a 5 gallon? I know I'm splitting hairs but I was wondering if the 4.7 gallon tank that came on the Dyna low rider s would work? Love the channel sir
@@mikeessary4925 thanks Mike, yeah mate I've seen blokes on the facebook street bob group have put the softail low rider S tank on (Not the Dyna low rider S) with no issues. I've purchased a 2019, 5 gal softail slim tank and am waiting on purchasing the 5 gal fuel pump and sender unit before fitting it 👍
Cool ideal . U did something on my Road Star ran it over 4 years with just pod filters but ran mine to back of the motor off to side. Change it every other oil change never had problem
Great video! Simple explanation and good filming of the installation I will just leave the filter but I put it more on the side and higher. I am using the breather bolts from DKCustoms but will change to the hoses like you did.
you prolly dont give a damn but does any of you know of a method to log back into an Instagram account? I stupidly forgot my password. I love any assistance you can give me.
@Lachlan Jaziel Thanks for your reply. I got to the site on google and im waiting for the hacking stuff atm. Looks like it's gonna take a while so I will reply here later with my results.
thanks for posting this👍 Could you tell me what the OD of the tube is,. please? You have commented you used a 13 mm drill bit, did you file this out to a bigger size? The grommet itself, what was the thickness of material it was designed for 3mm? could it be done without a grommet?
I did some research on this after watching this video and this is what I learned, since there are tons of videos about this, just dealing with cars and none of the Motorcycle ones get all the information correct, they are half right or trying to sell a product. 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. Oil catch cans, do not solve the problem completely, and carbon will continue to build up. The final solution is to take the engine apart and use a walnut blaster and clean the carbon off directly. Almost all motor vehicles are moving towards direct injection, there are a few manufacturers that have solutions, like Toyota, but none of them would apply to Harleys without radical redesigns of the engine.
I do understand this mod does not completely rid the engine of all carbon build up. That said this mod diverts oil from the heads away from the intake. Do you believe that venting oily mist from the heads into your intake will have no effect on any carbon build up?
Check out the recent video DOC Harley, (a harley Davidson technician) has to say about this mod. Curious if you will still disagree with me. Here's the link. th-cam.com/video/LoVuOuhFvDs/w-d-xo.html
@@TheGingybeardMan It is a minor issue, it is not as big of an issue as people are making it out to be, I already had seen the video you linked. Cars have been dealing with this for over a decade now, there are ways to deal with it, and most cars get along fine without any modification, even in to the 100k-200k range. Motorcycles, rarely see that, most people with 20-30k miles will never have an issue. Especially if it is highway miles and you are not working the engine that hard.
just put a 124 s&s kit on mine at 7500 mi it had alot of carbon build up there was more on the rear cylinder than the front but the head gasket was failing and getting oil from the oil cooler hole but the 124 kit comes with multi layered gaskets and plugs for the oil holes
Sorry man it was that long ago i did this vid I can't remember what size socket I used. If you have a full set of imperial sockets you will find the correct size. I'm not that pedantic with tightening smaller bolt on parts to torque spec, I use loctite on everything and just tighten it untill I know its tight.
When you say oil coming out everywhere, where was it coming from? This mod does not perform the same roll as the vented dipstick. The vented dipstick relieves crank case pressure while this mod onky diverts lil pressure away from the intake. This mod does not relieve crank case pressure. Oil coming out of your intake is usually a symptom that your oil level is too high. I assume you didn't notice this whilst having the vented dipstick in place as it relieves crank case pressure as stated
@@TheGingybeardMan all I know is that when I added the DK canister oil started seeping from the top of the motor from somewhere. If it keeps happening I will pull the tank and look deeper. Will let you know.
Great vid dude. I was thinking about changing to the extreme flow and moving to external venting and this has sealed the deal for me. Love the tip on changing the pink to the black also! Good man.
They are both used for two different purposes. The vented dipstick is used to release crankcase pressure in the bottom end while the external breather mod is used to divert oil residue away from the heads so your pistons don't build up excessive carbon.
@@paulson9616 I'll be looking at getting the latest oil pump for my 2019 model next. Harley made some revisions for a better performing oil pump on the 2020 models. The vented dipstick is pretty expensive here in Aus
Where would you mount the catch can to? Or are you not going to run a catch can? You would also need to run stainless steel tubing as the heat in between those cylinders would melt the rubber hose
Just curious why you used red Loctite and not blue? You’ll have a hell of a time taking those breather bolts out if you ever need to remove them for some reason.
Thanhs for all of the great information and instructions. I have a 2020 Softail Standard, basically the same machine as your’s. What tuner did you use? I’m considering either the V&H or the Power Commander.
You don't need a catch can which needs regular emptying. Just run a tube down through the swing arm to the ground. If you park your bike in the garage like I do, place a folded paper towel underneath it to catch the one or two drops that fall for the first few hours after a ride. Then throw the paper towel away. The black rubber tube on my Sportster is not noticeable unless I point it out to someone.
It will always be hard to notice the difference between the two ventilator air cleaners with a stage 1 upgrade being aftermarket exhaust, air cleaner and tune however I think the extreme ventilator is necessary when going with the stage 2 upgrades I did, being the torque cam and tune to suit.
Great video man! thinking of doing the same on my SB21. Q : do i need to tune up after? I've been reading other forums no tuning is need on M8 after doing Air elements or slip on mods but was wondering if it applies the same to the catch can setup. TIA!!
When ever you change the exhaust and intake with an air cleaner you should tune your bike to suit as it will change the air/fuel ratio and your bike could run lean. If you just do the external breather mod no tune is needed as it does not changing the air flow, its just diverting the oil from the heads away from the intake.
Thanks mate. Yeah I've seen the vented oil caps man, I think they're a great idea, I'll be doing that in the future also 👍 Not sure if I'll spend the big bucks or do the DIY option. Knowing me I'll probably give it a crack myself 👍
I've just bought one of these reservoirs in the link below, as I plan on using the bracket. It'll arrive in the mail soon enough so I'll do a vid on whether it works 👍 www.ebay.com.au/itm/174155266883
IF YOU DONT BELIEVE THIS IS NECESSARY, SEE DOC HARLEY'S VIDEO ON EXTERNAL BREATHERS.... CHECK OUT HIS VIDEO LINK: th-cam.com/video/LoVuOuhFvDs/w-d-xo.html
Hot oily air is definitely not needed into the intake. If you only do 1 mod to a bike, I think this is number 1

Thanks mate, was easy enough to do and if extends the life of my engine it's sure worth it 👍
Nice! Very thorough too. Thank you. I think I'll add some super glue to the grommets just to make sure nothing gets sucked in the intake.

If your oil level is correct & engine is NOT sumping..

I have mate but they're close to $350 Australian. I hear they help with sumping.
@@TheGingybeardMan I trying to order one now 237 American dollers 180 English pounds. It made.
every single harley no matter what engine needs oil diverted from air cleaner, older models had lower crank case vent lines

Sorry man it was that long ago i did this vid I can't remember what size socket I used. If you have a full set of imperial sockets you will find the correct size. I'm not that pedantic with tightening smaller bolt on parts to torque spec, I use loctite on everything and just tighten it untill I know its tight.
Sweet vid brosef, the blacked out air filter looks heaps better 👊
Thanks mate, I agree 100% I never liked the pink look
The problem I had after doing this was oil coming out every where it seemed. Put the vented dipstick back in this weekend see if that helps
When you say oil coming out everywhere, where was it coming from? This mod does not perform the same roll as the vented dipstick. The vented dipstick relieves crank case pressure while this mod onky diverts lil pressure away from the intake. This mod does not relieve crank case pressure.
Oil coming out of your intake is usually a symptom that your oil level is too high. I assume you didn't notice this whilst having the vented dipstick in place as it relieves crank case pressure as stated
@@TheGingybeardMan all I know is that when I added the DK canister oil started seeping from the top of the motor from somewhere. If it keeps happening I will pull the tank and look deeper. Will let you know.
@@garryr7856 yeah right, I havnt experienced that one, please keep me updated 👍, curious if that would happen if you ran just a pod filter
Thank for tip as I have a street bob thanks man
real pro job very tidy
Thanks mate 👍
slt super encore ta vidéo tu as commandé ou les accessoires.. diamètre du tuyau pour faire cette manipulation.merci.Phil
Zip ties the best invention ever
No doubt about it 👍
Thanks for the doing the video. What did you end up using for a bracket to hold the catch can? I want do put this on my trike. Thanks
I did another video you can see on my channel in relation to the catch can.
Great mod
Hey Buddy , love your Video's , Where did you get the fittings from ?
Great vid dude. I was thinking about changing to the extreme flow and moving to external venting and this has sealed the deal for me. Love the tip on changing the pink to the black also! Good man.
Good job
Great video as always... what your opinion on external breather dipstick besides external breather for air intake?
They are both used for two different purposes. The vented dipstick is used to release crankcase pressure in the bottom end while the external breather mod is used to divert oil residue away from the heads so your pistons don't build up excessive carbon.
@@TheGingybeardMan are you planning to the mod for vented dipstick in near future?
@@paulson9616 I'll be looking at getting the latest oil pump for my 2019 model next. Harley made some revisions for a better performing oil pump on the 2020 models. The vented dipstick is pretty expensive here in Aus
@@TheGingybeardMan cool. Let us know when you do that mod. Thanks
As always, great vid mate.
Thanks man, appreciate it 🤙
Nice work..
Thanks mate 👍
Run the 2 x 6mm vac hoses out back aircleaner through Cylinders and down through engine and primary case gap job done , my thoughts
Where would you mount the catch can to? Or are you not going to run a catch can? You would also need to run stainless steel tubing as the heat in between those cylinders would melt the rubber hose
@@TheGingybeardMan yeah i dont think it would be a issue for heat could allways run braided, and i wouldnt put a catch can
Just subbed, best DIY video for this, you mind letting me know what exact bracket you used off eBay?
Thanks mate, I did another video on the bracket I used to hold a catch can. I've listed in the description all the parts required for this mod 👍
@@TheGingybeardMan my fault I realized you had it in the description! Thanks a lot I’ll check out the other vid for sure!
🔥🔥🔥🔥
Just curious why you used red Loctite and not blue? You’ll have a hell of a time taking those breather bolts out if you ever need to remove them for some reason.
Ive alreasy cleaned the filter, locktite was not difficult at all to loosen
Thanhs for all of the great information and instructions. I have a 2020 Softail Standard, basically the same machine as your’s. What tuner did you use? I’m considering either the V&H or the Power Commander.
Hey man I did a vid on what tuner I chose and the reasons why. I went with a maximus tuner.
i cant seem to access ebay for the bracket to hold the catch can. do you have an item #?
9:02 ❤
Great video mate
Thanks man 👍
You don't need a catch can which needs regular emptying. Just run a tube down through the swing arm to the ground. If you park your bike in the garage like I do, place a folded paper towel underneath it to catch the one or two drops that fall for the first few hours after a ride. Then throw the paper towel away. The black rubber tube on my Sportster is not noticeable unless I point it out to someone.
Correct you don't need to run a catch can but I'd prefer to 👍
How does the Extreme ventilator compare to the regular ventilator performance wise?
It will always be hard to notice the difference between the two ventilator air cleaners with a stage 1 upgrade being aftermarket exhaust, air cleaner and tune however I think the extreme ventilator is necessary when going with the stage 2 upgrades I did, being the torque cam and tune to suit.
Tune needed after mod?
now that i looked at this video i understand, very informative lol
What socket did you use for the screamin eagle extreme air bolts? They look like some type of tamper proof set up
Great video man! thinking of doing the same on my SB21. Q : do i need to tune up after? I've been reading other forums no tuning is need on M8 after doing Air elements or slip on mods but was wondering if it applies the same to the catch can setup. TIA!!
When ever you change the exhaust and intake with an air cleaner you should tune your bike to suit as it will change the air/fuel ratio and your bike could run lean. If you just do the external breather mod no tune is needed as it does not changing the air flow, its just diverting the oil from the heads away from the intake.
@@TheGingybeardMan I appreciate the quick response and for the info. TIA!!
Good shit bro. You should also vent the oil cap. There's a DIY you could do or spend $300 on the fancy one. Do the DIY brotatchip
Thanks mate.
Yeah I've seen the vented oil caps man, I think they're a great idea, I'll be doing that in the future also 👍
Not sure if I'll spend the big bucks or do the DIY option. Knowing me I'll probably give it a crack myself 👍
Same one ☝️ I have ... works Great ! 👌🏽👍🏼.. woot woot 👍🏼🇺🇸
Well done 👍🏻
Cheers mate 👍
If you don’t mind Can you send details on the bracket you ordered? Thanks again
I've just bought one of these reservoirs in the link below, as I plan on using the bracket. It'll arrive in the mail soon enough so I'll do a vid on whether it works 👍
