Thank you for the efforts my friend I have an 17 ultra and it was onenof the first things I have done and assembled dipstick vent from A1 cycles. And yes, it didnt help much for the blowby, but reduced it. So I then reroute the blowby tubes out of the ac box, down to the ground, problem solved, no more stivky oil mist inside the air filter. Keep the good work. All the best.
Thanks for sharing this experiment on the venting. I think diverting the blow by from the air cleaner breather bolts may be the next step. Ive thought about doing that on my bike. Ride safe and enjoy. ✌️👍👊
I'm going to ask a question and please correct me if I'm wrong. The blow by tubes at the intake are to vent the engine crankcase. You installed the vent into the cover of the transmission. My assumption is that the crank case and the transmission sump are separate and likely sealed from each other due to different oils. Venting the transmission won't vent the engine case???
Actually under transmission cover are 3 separate compartments and one of them is connected to crank case. Transmissions vent is installed from factory and there is a tube coming out as original set up. Glad you questioned this.
Before you do that. The length of the hose adds restriction to the flow. So try shortening the hose or using bigger diameter. Also add the valve closer... right before the hose turns down the first time. Oil will not come back after it passes the highest point of the hose.
Thanks for this suggestion I thought about same thing. I have to say restriction was minimal when I blew into the hose but I feel same thing that length might affect things
I thought of this too actually I am tempted to try this solution without valve (as temporary check) to see if this will change things. I also wonder if hose isnt too long and if this affects things.
Dude your off your head, the crankcase vent will never eliminate the rocker box pressures or condensation, they are two seperate areas. The crankcase vent stops the oil frothing due to excess crankcase pressures which made it difficult for the pump to scavenge the oil. Harley addressed this with a later pump but the bike still has issues with frothing oil and and wet sumping ie oil collects in the bottom of the crankcase. Your crankcase vent eliminates this frothing. The maintained vacumme with your one way valve helps ring seal. Head breathers vent condensation and oil mist into the inlet, it takes a few months for this to happen from new. Harley did new style vacumme head breathers which are supposed to eliminate this issue but even these new units can fail. Only cure is to block the path of the oil into the inlet with silicon and run seperate vents from the head breather bolts to a catch can or vent to atmosphere. Never block these altogether as will cause excess pressures inside head and blown gaskets.
I am waiting for my warranty to expire to do vent in AC. Surprisingly some people reported no head blow by after installing Trask cover. As you could see that was not the case in my motor. I plan to vent heads straight to the ground as it is minimal amount coming out of there but yes after 3000 miles it accumulates and clog my AC filter. Thanks for your comment and hard not to agree seeing results which had minimal or no impact. Glad I didnt spend $350 on Trask cover
@@RidersUnited head breather venting to a catch can or atmosphere wont affect your warranty ask them, harley has known for a very long time that venting into the inlet is bad for the engine. It's part of emmission controls they have to impliment, mind the dealers have made plenty of money out of it, with customers having running issues even engine cut outs, lumpy starts. Thats aside from the extra carbon build up on the piston crowns. Its about $100 for them to remove the filter clean the pathway and inlet manifold/IAT sensor which it can directly affect and refit filter. As you already know it takes a few months for the goop to recreate the pathway to the inlet, sometimes several thousand miles. That could be a new season with a winter rest to a rider before they're back at the dealers for another clean. On a new M8 bike with a trask cover fitted they might yet not have experienced goop in the inlet, maybe they think its preventative maintainance. If the factory fitted M8 new vacumme style umbrella valves work as they should they might never experience head breather goop. Though even these new style vacumme umbrella valves have been known to fail hence why there is an expensive after market for that particular item.They even make one for the twin cam, Trask do a Mystfree kit, on the M8 there is the Fueling 3250 head breathers and the Cycle Solutions T-man performance breather valves. On the early twin cams that never needed crankcase venting they will almost certainly be experiencing head breather goop to some extent, that said. All harley engines are not created equal, atmospheric pressures and climate temps do play a part to an extent. On newer M8's it could take a very long time before that engine vomit makes its presence known, trask fitted cover or not. Plenty are still in denial.
@@paulsmale5436 big thanks for all the great info. I truly appreciate it and I am sure many people watching my channel will read your insightful comment and learn what you shared. Big kudos for taking your time and explaining in details. Super helpful for sure 🙏
It’s my understanding that HD is venting through the cover now on the new 117 motors. It’s been said this may have been something They intended to do in the past with the cavity design already implemented in the casting.

Nice work! in 2017 you might also want to check this oil pump I have video on this as well ruclips.net/video/mmvYLWmJJxE/видео.htmlsi=LdmReg4F0XAHmSNd
Thank you for taking your time to share your knowledge!
Thank you sir
Nich work bro! Very informative 😊
Appreciate the comment
Good tutorial 👍
Thank you 👍

Yes I feel this is next logical step here. I just learned new CVO have completely redesigned system
good video!
Glad you enjoyed it

@@RidersUnited Thanks for the explanation - now I know the story!
@@carlgilmore9821 always happy to help and thank you for watching really appreciate it
@carlgilmore9821 sure thing
How did this work out in the long run and did you notice a difference in how the engine responded? Was there a marked difference?
Now HD offers OEM upgraded cover it is for 2024 CVO so I would recommend this solution over self made option
Now HD offer OEM upgraded cover for 2024 CVO models that is even better option

Don't have any issue with the breather. 53000 miles. I do like the idea of moving the 1 way valve away from the case. Not sure how far tho.
Thank you sir
I think your vent and hose is not large enough. I used a much larger fitting and hose. Mine seems to be doing the job.
I thought of this too actually I am tempted to try this solution without valve (as temporary check) to see if this will change things. I also wonder if hose isnt too long and if this affects things.
Use a plastic nut with the lock tite.
I might consider this
