I apologize in advance 🙏🏻 - but due to my busy schedule I probably won’t be able to see your comments or questions unless you are subscribed to my channel as I filter subscriber only … hope you understand- sorry.
Sandy great video, just be careful with how much K&N oil you put on the filter. Put just the bare minimum to cover it. ( I have found the K&N oil spray bottle works easier) If you put too much oil on the filter it will get sucked into the intake and gum up and ruin you MAP sensor and the air sensor. Look it up online if you don’t believe me. There are plenty of posts on this problem happening.
That's a problem that's been magnified by the M8s, the crankcase ventilation system isn't able to keep up with the added compression and displacement that the M8s produce. I would recommend keeping your breathers connected to a vacuum source as most vehicles on the road do(pcv system), the added benefit to a vacuum source is it helps evacuate crankcase pressure(vacuum in a crankcase can add HP & mileage). I would also recommend the Trask vented trans cover(helps the overworked stock vents), in addition adding the Feuling short sump plug, it can help the oil scavenging by opening up the space where the oil pump has the ability to suck out more oil. These remedies won't 100% cure the oil in the air cleaner but it will help tremendously. Back in the old days the shovels and pans would just puke out a little oil onto the ground via a vent hose(marking it's territory) so the EPA made Harley come up with a more "environmentally friendly" system. Hope this helps. God bless
Sandy said that he has the crankcase ventilation through the Trask cover, and no, you do not need a vacuum source connected to the PCV system. The Positive Crankcase Ventilation system does not need a vacuum because the umbrella valve opens up only if there is positive pressure inside the head not matter if there is a vacuum source or atmosphere pressure at the other end. Sandy has done it right.
Here’s my problem with this mod, I haven’t had any breather mods done yet but will do trask cover soon. The trask cover has a check valve built in, this stops air being sucked into the engine when cooling down. The oem breather system sucks air back into the engine when cooling but it passes through the air filter usually oiled. All air has a certain amount of water in it depending upon the day. With a direct breather to atmosphere, you will get more direct airflow with moisture back into the engine. This is where I see so many people looking at the catch can or pipe work to say “look at all this goop that I saved from my piston getting”. When in fact by this mod you allow more air out during running the engine and more air/water back in when cooling. I sincerely am not a mechanic just over thinking the whole mod. I have seen some people place a check valve into the air filter breather mod which I think is better.
I run the Trask breather, fueling breathers in the heads, fueling air cleaner and cam chest. Works perfect! (Not cheap!). Synthetic oil does not burn! It causes massive carbon buildup on the pistons. Cars and trucks have the same problem. The Trask trans cover vent is by far the best solution. My buddy made his own by drilling the stock cover. It works fine for a lot less money.
Thank you Sandy !! I am surprised none of your riding buddies have done this! I use the trask transmission cover and run oil 1/4 quart less and no more problems! Peace to you brother!!
The Feuling vented dipstick or Trask transmission vent does help a lot with oil going into the filter. My Street Glide had 1800 miles then I installed the Dipstick and external breather for air cleaner and had a lot of oil inside the intake manifold and oil filter. My brothers Street Bob we installed the Feuling vented dipstick as soon as we bought it and very little oil in the air cleaner and throttle body after 2500 miles. About to install the external breather for it too.
Sandy check out Green filters I’m pretty sure they have black oil for your filter and if you want more air to get in to the motor check there filters. I’m looking at doing the same thing but I ordered banjo style bolts so my hoses will hook up behind my intake housing
*You should really get a DK Customs outlaw air cleaner system, with the external breather system, or at least call them, to ask what you need, for just the catch can. They have a lot of good products. I have one of their air cleaner systems, and I noticed the difference. Another thing that you might want to check into is footboard extensions.*
great video, I put a camera down through the spark plug holes and the pistons where covered with gum and oil , know I vent into the atmosphere, pistons tops have cleaned up.
I bought a 2015 103 Dyna Fatbob, a few months in which was basically enough time for the cleaned breather system to re create its path to the intake the bike started having problems. High revs coming down gears clutch pulled, slow speed cut outs, re starts and re cut outs, eventually clearing. Lumpy starts. Removal of air filter showed oily residue fouling the IAT sensor, being in the fuel tract it could clean itself but it still caused issues. Harleys fix £80 clean and a few months later the problem re occurs. Fitted a DK Customs Catch Can sitting just below the heavy breather between the push rods slightly above the timing chest. Blocked the pathways from the head breathers with fuel resistant silicon sealant. No more problems. Should the sealant be sucked into the intake which I highly doubt would happen, the engine would just spit the soft compund out rhe exhaust port. Your cure looks un sexy as do most of the basic rubber hoses exiting air filters. I used black anodised end fittings though had to modify these to accept stainless quality jubilee clips and black braided hose with black painted brass fittings. Check it out end of video czcams.com/video/NXqZBmcgKSQ/video.htmlsi=cNnV5LmAc8XMo9-S Also show cased on the DK Customs website under pictures. Intend to fit a similar device on my M8 though being as we're back to a single cam and now have a ride by wire module in the way will route the breather over the heads and down below the coil. Should look sweet if done right. System will still vent high as ran simlar setups on X1 buells using forcewinder air filters which routed up and over.
Hi 👋, Sandy and Family and Friends, I hope you all had a great Christmas 🤶, and wishing you all a Happy New Year 🥳, strange, how laws have changed about emissions, some I don’t think are for the good, I have used K&N air breather kits, on all my vehicles from back around the 70s, Doesn’t matter whether it is my bike or my car or my van, After watching your territorial pouring oil onto your filter, I had a quick look on Google and even went down to the basement to look in my fluid cabinet , and I have still got my K&N oil , which is an aerosol, and yes, I said aerosol not arsehole 😂. I believe the aerosol gives you a more even coating ., of oil over the filter, Ride Safe, Happy New Year to everybody hope you all have a great one , 🎉🍷🍾. Phil from the moulin France .
The Trask tranny vented cover is the trick... it works fantastic. I get zero snot out of my head breathers. I also run the head breathers to a DK Customs catch can, which I installed inside the breather box. Dirty air does discolor the filter where the catch can is placed. However, it is minimal. I change my stock filter every 1000 miles. I only ride 2000 miles each year. I see people over oiling their K&N filters. They require just enough oil to cover the entire element. The best approach when oiling is to lightly spray the filter and let it sit for 20-30 minutes. This allows the oil to spread and penetrate. If there are white spots, reapply just enough in those areas. Repeat the cycle as needed. Also, if you over fill your crankcase with oil, you will get an oily mess on your filter. Never add oil to an M8 unless the stick reads at fill line or below. I use the cold check method. When I return from a ride, I keep the bike upright and let it idle for two minutes and then shut it off. When the bike cools down, check the level. It should be at the halfway mark. If it is, you are good to go. I have found that using the hot check is inconsistent. My two cents. Best of luck :-)
Yeah take your throttle body off and look in that intake manifold and see how much oil is in there. It will blow your mind. I just upgraded my intake manifold to a hpi ported and polished with new injectors. After seeing how much oil was in the stock one I wasn’t going to start the bike before I did the breather mod.
John, (AKA Blockhead on CZcams) and his mechanic did something simular a year or two ago. Those screws that you use didn`t exist then so they used three zerc fittings, two where the blow buy comes out, then rubber hose to the T then more rubber hose to the last zerc fitting in a drilled then tapped hole in the oil resovar top.
How dit the bike run after s&s filter and external breather ? Did you run it for a long time without maping again. ? I have 117motor and tuned with stock filter and s&s exhauste. Looking for do that filtersetup with the same breather setup. I dont whant to pay for tune again😮
I have a 1995 fat boy that somebody put a K & M filter on and it has really weird breather bowls that I don’t know how to get out. They have like a large X slot in them. I wish I could share a picture here
I did this to my twin cam 103.. never really saw much in the can at all.. I'm thinking some bikes do this more than others, and/or, people are overfilling their oil tank ??
On a level surface, a cold oil check. The oil level on the stick should be dead center. Any more than that, that's when the problems start. How do I know? Been there done that.
You can NOT vent to atmosphere not epa compliant. And I have never had an issue with 2023 M8’s. stock or stage 4 Harley builds. I have three stage 4 Harley builds 140 plus horsepower zero issues.
Two things motorcycles make zero Environmental impact it’s a joke and the other I use the aerosol because you want a thin coding on the K&N filter you don’t want too much
LOL only on an HD! 120yrs and they still can't build a proper bike. You'll never have to do that on your Wing! My '22 M8 didn't spew oil out but my TC103, 95 did!
You will not have to do that with Harley M8 too. But you better do it with the Wings too. All EPA complaint ICE engines have the PCV system, but only with the Harley it is soo easy to do that.

There’s a one way valve in the actual breathers on each cylinder head.

I did the Fueling vented dipstick. Works wonders.
I did the same, zero issues.

Thank you buddy. Glens RK has a vented dip stick and a breather too. Nedals bikes are vented . Only John doesn’t have it …😂
This is a great idea and it looks pretty clean overall. Nice dude!

I didn’t realize that but I actually think the trask breather cover did help a bit . I’ll check the catch can in a few weeks and post
I have a 2016 camaro ss that needs a catch can great idea.

Great video sandy very informative
Thanks James
Great video happy holidays to you and your family and happy new year
Those hose will slip right off breather bolts. Oil will also coagulate in tubes especially in winter cold .
Is there going to be a follow up video to see the gunk that gets caught in the oil catch can ??
How dit the bike run after s&s filter and external breather ? Did you run it for a long time without maping again.
?
I have 117motor and tuned with stock filter and s&s exhauste. Looking for do that filtersetup with the same breather setup. I dont whant to pay for tune again😮
They have the same kit with oil in a squirt bottle, way easier to apply evenly.
Thank you for the info
Put the DK customs Transformer External Breather Kit on all my bikes owned.

That breather oil contaminates the air filter also, so venting externally is best...
K&N does have a black oil .
Hi Sandy. I was wondering if your air filter might now be sucking in additional air in the absence of the S&S breather bolts.
I don’t think so - they are the same diameter as previous bolts - nothing changed the fact that the air only comes through the filter
great video brother .
what’s the exhaust your running ! thinking of going to a 2-1 my self
Thanks 🙏🏻 brother ! That is a Sawickispeed 2-1 stainless steel . Performance is great and the sound is amazing!
And thanks for being subscribed
I thought you had the vented dipstick
You can NOT vent to atmosphere not epa compliant. And I have never had an issue with 2023 M8’s. stock or stage 4 Harley builds. I have three stage 4 Harley builds 140 plus horsepower zero issues.
Manufacturers can’t vent per the EPA but nothing prevents individuals from modifying.
I hope nobody calls the police
Hello Sandy , you never commented on the replacement bolts with the hose nipples, what size and where did you get et them.? Thanks
Are you subscribed to my channel?
K&N has a recharge kit with black oil. 🤯
Two things motorcycles make zero Environmental impact it’s a joke and the other I use the aerosol because you want a thin coding on the K&N filter you don’t want too much
K&N Air Filter Oil - 12.25oz - Aerosol
Yeah that’s a good option too
LOL only on an HD! 120yrs and they still can't build a proper bike. You'll never have to do that on your Wing! My '22 M8 didn't spew oil out but my TC103, 95 did!
Zero issues with M8’s. Attempting to fix a problem that doesn’t exist which will surely only create other real problems lol
You will not have to do that with Harley M8 too. But you better do it with the Wings too. All EPA complaint ICE engines have the PCV system, but only with the Harley it is soo easy to do that.
that's what i don't understand. Sandy's is an M8 and my M8 didn't have any issues.@@uutube243
will or will not have to do with M8? I had no issues. with my M8. OR my Wing! @@kadimsilahtar
