Transformer™ External Breather System for Harley's

[@DKCustomProducts]

These are available for Sportsters, Cable operated throttle Twin Cams, and all Milwaukee-Eights. It will be another month or so before we have inventory for the Throttle by Wire Twin Cams.

[@ronadamson4595]

Anything for a carbureted EVO?

[@thatoneguybrian2365]

From one engineer to another, i would recommend creating a fitting that allows you to screw a catch can directly to the bottom of the support bracket. This eliminates hoses all together, there's already space in that area for a catch can as many people mount the DK directly below the air cleaner anyway.

[@DKCustomProducts]

Yes, that would be nice, but the top of the catch-can would hit the air cleaner backplate.

[@richardrussell500]

my thoughts exactly...

[@2wheeltravel401]

Then redesign the catch can. I will by when you have it with no hoses. For my 2022 road glide limited. Nice job.

[@richardrussell500]

@@2wheeltravel401 I agree 100%... they (DK) need to do some R&D with a catch can mounting system.

Looks pretty simple to change back and forth (external versus internal venting). Of course, I'm sure that nobody would ever consider venting internally one day a year just to pass an annual EPA inspection (then vent externally the other 364 days) 🤣😂. Looks like a real winner DK!!

[@DKCustomProducts]

Thank you! 👍 It really is good to be ready for whatever happens in the USA. Outside the USA there are already some places that need to be emissions compliant, and this is the answer for them right now.

[@chazzcapone.]

This a brilliant all purpose solution that’s compliant and subtle if someone opts to vent. I sincerely hope you guys have a Patent pending or application pending for the work you’ve done. It’s not only creative but lucrative and don’t let some corporate hack steal your hard work, thoughtful design, and solution for the HD engines!! Get on that and start stamping it patent pending with the application number. It’s a easy process that’s done online.

[@DKCustomProducts]

Thank you for your kind words. We appreciate it! Yes, we have filed our patent application, not a difficult process to get a patent, just a long one. Over the years we have well over a dozen patents. It does help in most countries to stop folks from copying our work. Unfortunately Chinese companies will steal designs, and there is not much that can be done about it....at least on our level.

[@williamvaughan6448]

I just installed the Transformer tonight along with an Outlaw air cleaner (578). The transformer was an easy install and hats off to DK for making this tidy. I would suggest some additional attention to deburring the plate surface, but a little time with emery cloth and all was good. I think the o-rings and grooves could be thicker as well, but as long as they seal, right? Curious as to why the light aluminum breather bolts? They were well made, but I did worry about torque on installation, thinking about the heat cycles. The only thing I'm not happy with is the air cleaner fit. I've spent a lot of time trying to get good alignment, and there's only the outside flat plate (cover) applying center pressure to seal the filter...a little worried about leaks. All in all, excellent product, and we'll see after some miles!

[@DKCustomProducts]

Great to hear you are liking the Transformer. Thank you for the reveiw. On the 587, if it is overtightened it will make the filter element go out of round. There is a video link below on the 587 install, and starting around the 7 minute mark we go over the installation of the cover. If it is snugged down there is no worry about leaks. I have run various 587's on my bikes for well over 100k miles and never had an issue. This is because of the unique mating surfaces that K&N uses on either side of the filter element. It seals well with minimal pressure. As noted in the video below, if you want to be extra cautious, use a little oil on the surfaces, that is double protection. kzbin.info/www/bejne/l6eyc3qdbM2ZedU

[@williamvaughan6448]

After 3 weeks and 1200 miles (mostly highway miles, generally 3000-3300 RPM cruising)...all good! Checked catch and it was clean. I'll check again at 5000 miles. I also run the feuling dipstick...clean filter there as well. Everything good with the transformer, and again, great job!

This is a great system guys. Very ingenious. I suppose in some situations a biker might choose to switch between EPA compliant or non-compliant, based on the inspection schedule. Obviously I do not recommend trying to fool the gov't in any way, shape, or manner.

[@DKCustomProducts]

We do not suggest trying to fool the Gov either. There may be a situation where you are visiting an EPA compliant state or to have the option if your state becomes EPA compliant and you do not want to spend the extra money for a whole new air cleaner set up. Thanks for commenting! 👍

[@jeffreyengle2762]

Makes total sense for the twin cams, or any bike that is unable to vent directly through the trans top cover. In my opinion, venting the trans top cover on the M8’s is so much cheaper and a much cleaner solution…. Trask checkm8 (or simply diy) then I don’t need to mess with the stock breathers whatsoever… problem solved.

[@DKCustomProducts]

Thank you for your comment. That vent will route some of the oil, but not all of it, away from the air cleaner. It is still feed hot & oxygen depleted air into the air cleaner. There are 3 measurable benefits to a True External Breather System 1. NO oil into intake to gum up sensors and build carbon deposits 2. NO hot air into intake which robs power. The colder the air charge the better. See video below 3. NO Oxygen depleted air into the intake. The only reason to put air into the intake is for the oxygen. Putting oxygen depleted air in is a total waste and robs power. Vents that relieve pressure, like you mentioned, are a band aid that only partially address the problem. kzbin.info/www/bejne/e5enlnmQl9GAmc0 kzbin.info/www/bejne/qnu7eHitgaiBetk

@@jeffreyengle2762 Not sure what you are disagreeing with? That hot air is bad for making power? That oxygen depleted air is bad for making power?

[@jeffreyengle2762]

@@DKCustomProducts in all honesty I’m not disagreeing with any of it, what I am disagreeing about if I’m disagreeing about anything is the fact that after I did my trans top cover mod, it reduced all oil down to roughly 1% of what it used to be. Which in my opinion is a absolute success. It’s not worth it in my view to spend another 200 or more dollars trying to take care of that one percent. Hope that makes sense.

[@DKCustomProducts]

@@jeffreyengle2762 Understood. That is great that you got 99% of the oil to stop migrating to your intake. It would be good if everyone was that fortunate. Some spit more than others. Have you seen our balloon test? Here is a link to it. kzbin.info/www/bejne/gZrSZXd7qrSjebc The red M8 around the middle of the video puts out a lot of hot oxygen depleted air, but virtually no oil. So he is running an EBS to stop the hot oxygen depleted air. Many are not so lucky on the oil migration. I would not spend any $ to get the last 1% of the oil either. I wonder how much hot oxygen depleted air you are still getting though. That is as much a power robber (actually more) than the oil. Oil is more about sensors gumming up and build up on the pistons resulting in tune instability. Here is a chart showing how much flows- www.dkcustomproducts.com/breather-system-flow-testing-results-video.htm We have several tests scheduled to measure on a variety of bikes...but every bike is a little different, so if you ever do a test on yours, I would be interested in the results.

How about a catch can that has a second port to go back to the breather allowing the oil to stay in the can and the air to return to the throttle body giving the catch can a negative pressure to assist flow?

[@DKCustomProducts]

With a free flowing air cleaner there is no need for the hot, oily, oxygen depleted air to be filtered and re-routed back to the throttle body. The air would still be warm (performance robber) and it would still be oxygen depleted (another performance robber) Thanks for commenting!

[@MrBoatingdude]

Great concept guys, I am ordering one but I have a question: Will this need to be cleaned every so often since oil will be passing through such a small channel?

[@DKCustomProducts]

There are smaller passageways within the head breather system that the oil carry over and crankcase gasses pass thru prior to reaching the Transformer™. Clearing the passageways within the Transformer™ assembly simply isn't required BUT with that said, it wouldn't hurt to do it yearly. I have had mine installed for a few years and have never cleaned it and it is still running like new.

Those grooves in the plate look shallow. Does the transformer vent the same or more crankcase pressure as the factory setup? What about those guys building higher horsepower, higher compression motors? Does the transformer have the capability to vent the extra crankcase pressure those motors are making? Just curious if any testing has been done on that

[@DKCustomProducts]

Good questions. The channels are larger than the some of the channels inside the engine. So they will never be a choke point. Here are the channel dimensions. to center is .125" wide x .055" deep. to bottom is .07" wide x .1" deep. The largest engine we have tested on is a 124 with high compression, and there were no issues. While we have not tested the 131, inside the engine there are oil passageways that are smaller than in the Transformer™, so there will be no restriction.

Unfortunately, no. The Transformer™ is only compatible with air cleaner systems equipped with breather bolts that do not pass thru the backplate. Here is a video showing what it will fit and what it won't fit- kzbin.info/www/bejne/lYm8iYaZrpidZrM

Interesting product, i picked up an oil catch can, tried it out but the bike didnt sound right, I read up on the service manual and it states that the crankcase needs to be vented back into the engine for the critical vacuum (just venting outside will not give it enough vacuum), id love a product that would filter the oil and also vent back into the engine

[@DKCustomProducts]

Thanks for your comment. Could you please point us to where in the service manual "it states that the crankcase needs to be vented back into the engine for the critical vacuum".

Are you sure…. I’ve never read that and have never seen anyone concerned about that

[@drainmonkeys385]

@@DKCustomProducts I am pretty sure it doesn’t say anything like that

[@DKCustomProducts]

@@drainmonkeys385 Yes, it is appears to be a myth that is based on some thought that the intake suction is going to flow back thru the breather bolts, thru the umbrella valves, then thru the pushrod tubes, then into the crank and create a vacuum. This illogical thought (logical on the surface) first became popular among the early M8 owners that were having sumping issues due to the poor oil pump, as they were grasping at straws on what to do about the sumping. The faulty logic is the thinking that the suction in the intake would pull air via the tiny tubes, instead of the much less restrictive filter element.

[@DKCustomProducts]

@@drainmonkeys385 I would like to see it, if it exists.

[@bluecollarbiker8005]

Have a really good question oil that is getting vented is clean oil from the engine why not vent it back to the engine and not through the intake I mean theoretically it's clean oil correct so why not put it right back into the engine block

[@DKCustomProducts]

It is not clean...it is the worst of the oil in the engine. Much of it comes via blow-by, and then the route it takes to get to the breather bolts can get condensation from temp changes.

Why didn't you place that small piece of rubber vertically to prevent the small area above it from pooling oil? It would completely divert the oil around to both sides?

[@DKCustomProducts]

We placed it where it is because the positioning feeds best when internally vented. When externally vented the pressure pushes everything around to the bottom hose barb.

Elevation does not change how our parts work. However, at elevation the air is "thinner", less oxygen in it, so the ECM makes adjustments for that. We talk a bit about how elevation is dealt with in this video- kzbin.info/www/bejne/ZqfFhZ6Iq6uUbpI

[@DKCustomProducts]

You can clean your filter element...it will be close to white after that. Then either get some filter oil that is black, or you can add some black dye to the red K&N filter oil to darken it up. 👍

So there technically is no black filter? Ok. Thank you. I will look around and see if i can find one online.

[@DKCustomProducts]

@@Poopaw34 No, the material is a cotton gauze and is naturally a white tan color. Any black ones you see are either dirty, or have had a black oil applied to them The filter on your 587 is only reddish because the oil used has a red dye in it.

[@DKCustomProducts]

We are not making any specifically for a 64mm throttle body. However, this one will work with the 64mm Throttle Body on a TWIN CAM. It will NOT work with the M8 64mm. On the Twin Cam the inlet on the Transformer™ is a little bit smaller in diameter, this will give an Increase in Torque between 2400 and 4200 RPM, and it will be a bit of a Decrease in HP above 4200 RPM. So it depends on how you ride, if you want low end power or top RPM power.
