Thanks for watching. Let me know what you think in the comments below. More videos like this here: czcams.com/play/PLmgCmljtdCzWrLg62oZxo0laIsmq4j67P.html The update video for this is here: czcams.com/video/8TTy8Q1wKWI/video.html
I bought a rear brake reservoir for a Yamaja then drilled tiny holes in one end and put some foam rubber to catch the oil, then every once and awhile is clean it out.
The ends of your breather need to be outside the air box due to the oil mist. It will deposit oil inside the airbox and now you will have drips coming from that. I did the same thing at first and got an oily filter and smudges leaking from the area.
I have an 18 FLSB as well, I bought it with 1300 mi on it in Sept. 20 I'm now almost at my 5000 mi service. I have watched your channel and enjoyed it, Thank you. I'll be going to the dealer because I'm not sure if it ever had the first service. Then I think I'll be doing most maintenance myself. I have bought the DK Customs DYI breather and TAB exhaust will be installing both this week. For your viewers the DK DYI runs total 60.35 shipped here in the US. Definitely can be done on your own but the kit has a nice filter element or catch can for more money. I'm not a performance mod kinda guy I love the stock look and performance of this bike. I am more of a wanna make it mine change some of the appearance things. The stock gas caps rattled so much it was almost unbearable to ride (unacceptable by the way, my instrument panel also fogs) so I put on the flush mount caps (cheap plastic rings and false left side) really cleans up the look of the tank. Enough ramble thanks for the work you do on the channel. Cheers from across the pond, ride safe.
mm i was thinking of purchasing a sports glide in the future i would do the breather mod also the vented dipstick you showed soon as i bring the new bike home from the dealer..good instruction as i liked to make the motor to last a very long time..thank you
Your fuel filter breather end still need to be outside of the aircleaner box. If its near the air filter at all, it will still ingest the micro oil particles that do manage to get past the filters. Which will happen. Otherwise this only reduces the amount of re-ingestion, and it doesn't remove the hot air re-circulation either. The ESB is meant to dump bypass air away from the intake at into the atmosphere. Your design still still cause heated air to be directly ingested back into the throttle body. That big hole you're pointing it, it's negative pressure as the engine feeds air from that hole. So your little air filter is injected it's bled air directly into that intake stream. A bit like spitting water into the front of an Jet engine. Ziptie the little filter outside the box like you suggested your viewers do. That will be far more effective. Also have you prerecorded this stuff? You cant test the effectiveness of one over the other if you run them all at once. You'd need to do 1 with just the vented dipstick, make sure you increase the size of the hole you put in it before you do that. Then one with just air cleaner breather kit. Then one with both together. cleaning out the heads and pistons each 5000 miles. You'll need to run like 15,000 miles to get good data on this stuff.
I would agree the hot oily air needs to be dumped to atmosphere outside of the filter cover else there's a very good chance it will be sucked back into the throttle body at some point.
I bought some bits as well to set up an external breather. On my 2018 Softail Heritage I do have a reasonably noticeable issue with oil clogging up my air filter - up to the point oil spilling out onto the exhaust and saddle bags ( have not checked the cylinder heads). This happens at two occasions: riding in very hot weather and long days touring. I have done over 20,000 miles on it.
I did kind of the same with my 19' slim. But I ran the tubing out through the opening in the back plate ,up under the gas tank and routed the tubing down passed the oil fill spout (with a little routing behind the right side battery access cover) to under the bike . I also wasn't getting too much oil ( only a hint) but thought it would be better not having the very ,very, light mist going into the throttle body and on to the pistons. Its still cold here and won't know the outcome till I start riding this summer . I ran 2 separate lines and they were rated for +257 deg. F. and a working press. of 25 lbs. These were Gates hoses and are used for vacuum , windshield wiper fluid , and engine coolant overflow .
I have found your tips useful, keep them coming they provide good food for thoight. My 2019 Softail Slim drips oil from the air filter box after a 100-140 mile run. Harley dealership suggested oil to be central between fill and full mark which is how they service it. Every mechanicsl bone in my body tells me the Harley design leaves a lot to be desired. I intend to install breathers albeit to catch cans or filter. Ordered a new dipstick just in case. After watching
Hmmm interesting but it will be hard to actually point out what works if you do both at the same time. But I tend to agree with you, I feel that the dipstick venting would be a more effective solution. But above all that, the best way to avoid excessive blow-by is having the proper oil-level. Get the bike warm by riding it 10-15 minutes, Shut it down upright when back home then put it on the jiffy, Be around a quarter lower than full hot with hot oil. I found that SE oil is very sensitive to outdoor temperatures. I had bad blow-by and hard times fo find the clutch this summer. Now that temps are lower, it has greatly improved.
Yes the issue I have is really time as both would required another 10,000 miles or more to conclude. I'm not so concerned about any minute performance gains but really seeing if either or both of these help to minimise carbon build up on the pistons. Time will tell. Still experimenting at this stage.
I'm Looking forward to seeing your Results Alf..Mine Seems to Let off a Bit of Oily Vapour and in Your Case it May be More Pronounced due to E10 Fuel ..Either way It'll filter off the Oily mist and some hot Deoxygenated Air which can't be a Bad thing..
The best way to fix modern Harley Davidson Motorcycles would be to install a PCV valve between the intake manifold and one of the valve covers. Then a vent hose from the other valve cover to the air filter adaptor. That needs to be a "T" connector connected to a box with vent connections to the transmission, oil tank, and primary case. The box also needs to have a filter where it can vent to the atmosphere. You need that filter because when the engine is cold at start up the (new) vent system will draw air into the box and all the components it's hooked up to. As the engine warms up and heat travels to all the other components air will start to move both in and out of the filter open to the atmosphere. It's little wonder you have oil getting sucked or shoved into places it should not be due to the lack of a proper venting system.
Be interesting to see if the fuel filters catch any oil mist, the inlet of the throttle body looks clean on your bike as you say. I think there are also flap/one way valves in the built into the head before the vent bolts so the vents should not suck in air. Do you know if the oil pan is actually connected crankcase gas wise to the crankcase or is it just oil wise as in the scavenge pump returning oil from the crankcase back to the pan and the supply pump taking oil from the pan to supply the engine as normal? been trying to find this out to see if the vented dipstick is just going to vent the oil pan ( reduce oil transfer problem if it exists) or also vent the crankcases as well.
Yep got a follow up video tomorrow discussing this. As for the vented dipstick, yep I'll be discussing that in a follow up too. But those are interesting points as effectively they are separate but they aren't completely sealed I believe. Cheers
You are doing fine until you curved it upward....while the system is slightly pressurized it's off just as much as it is on because the flapper valves in the head are closed 50% of the time... What this means is oil vapor going horizontally or going down is no issue when you start trying to push it up .... Any residual oil will start pooling at the lowest point. So the entire lower rubber line that you put in is where your oil is going to sit it's not going to be pushed up to the fuel filter you'll end up with a lot of clogged lines and eventually your engine won't breathe. Not to mention since the end of the fuel filter is open and it's all contained inside your breather all you did was move it from inside the filter to outside the filter so the filter is going to be dirty much faster and need cleaning more often.
Oh and I would be very interested in seeing how you look at your motor with your endoscope ; maybe a little tutorial with Amazon links ? Thank you for the very good content, Sir ! Be safe :-)

Hey that’s a great idea. Never even crossed my mind for that. Cheers
Tied the air box bypass hose to my Fueling vented dipstick line just in front of the filter.

Check out the Memphis shades El Paso screen for the sport glide looks superb
Any update on the EBS results? Is it worth it? Thanks
good video Rev but would like more close up pick of air box and the arrangment.....Thanks
I’ll see what I can do in future vids
My favorite bike channel. Well done.

@@RevelatorAlf Cant fix things and improve if you dont share potential mistakes with the world.
Yours is easy to fix so not a big deal.

I used the T and just needed only one piece of hose to the catch can.
check Trask has a new idea venting the g/box cover instead.

Nice topic, I have my doubts as well if it is not just a business thing or not. Curious what we will see after 5K. 👍🏻👊
Yes me too. Cheers

Thanks Simon yes I made a video a short while ago describing using the endoscope. Cheers

Owk ok.
I missed it then.
Thank you.
See how it goes? I have quite a bit of oil coming back on my 2017 ultra 😎🏍💨💨💨💨💨💨👍🏻🇨🇦
Ha ha well I can’t speed up time
The reason I did it this way is because I have a Cobra Powerflo air intake .

Not a good set up. Your still dumping suptz back into the air cleaner element and housing.
