Hundreds of hours of research and thousands of miles of riding have resulted in this 4 Stage Catch-Can that allows air to pass through but keeps the oil and water in the Catch-Can on typical Harley's.  

See the photo's of the 8 different components that make up the 4 Stage System.  Even with the worst spitters most of the water and oil stays in the Catch-Can!

Designed for the hot, oily, watery, oxygen-depleted air to pass thru the tube, exiting near the bottom.

Most of the oil and water will drop into the low density foam.  The air, and some atomized water and oil hits the first separator, stopping some of the liquid, but allowing the air to continue on through the high density foam.  There are two more separators and two more pieces of high density foam that work at stopping the liquid, but let the air exit the vent holes in the cover.

Periodic emptying of the Catch-Can is easy.  Simply unscrew the can from the lid and dump it.

Cleaning of the foam and separators is not necessary, but easy to do if one wishes.

There is an extra O-Ring included, should the installed O-Ring get lost or damaged.

There is also a refresh kit with extra O-Rings and filtration system that is an option or can be purchased separately.

Sometimes the kits have two thinner pieces of low density foam (as pictured above) other times it is a single thicker piece of low density foam.  Both versions function equally well.

See that kit HERE.

 

The EPA has required Harley to route hot, dirty, oily, oxygen depleted crankcase air back into the air cleaner compromising the performance & longevity of your engine. When using an External Breather System, your bike will run better and last longer.

This Catch Can is a nice option that will work with your Discrete or Premium Discrete Breather System.

Also available in Powder Coat Black Finish, see at this LINK

These have a Machine Cut Billet Aluminum Finish that can be polished to a Mirror Finish.  See photos.

Awesome problem solver! Review by Greg Ross
Three or four years ago my bike mechanic recommended I put together a drain set-up on the Sportster.
I have been using a K&S intake which includes horns to feed the produced goop straight into the throat of the Carb.
The set-up I put together included 1/8” tubing and a couple of tees I made from 1/8” brass tube. A drain line ran down behind the tranny.
On receipt of the new EBS Catchall with a roughly 3/8” inlet I concluded my 1/8” drain surely wasn’t cutting it.
I did find the bored bolts coming off the heads were plugged at the small orifice. Removed those head breathers and replaced my 1/8” nipples with 5/16” hose barbs soldered in. Made up as well a 3 ea 5/16” brass hose barbs soldered together to join to the new nipples and directly connected to the Catchall, it hangs just below the Carb (S & S Super “ E “) Easy access for draining.
The Carb has been jetted same as 1200 displacement. The bike has constantly fouled plugs, (fouled instantly if you happen to leave the Enricher on)
I looked at the old 883 pistons and they exhibited deposits I assume are courtesy of the injected GOOP over years.
I’ve run perhaps 1000 kilometres since fitting the Catchall and I am amazed at the volume of water and petroleum product being captured.
I’m convinced this EBS is likely the best new product to come to market in eons.
Thanks Dwayne and Co. This is a Winner.

another great product from DK Review by a## hole
A real fix to a problem that Harley says doesn't exist. Talked to the dealer where I bought my Road Glide Ultra and they said there was no problem with the Harley design. I'm a mechanic with over 50 years exp. I know the aftermarket has alot of better ideas. I like the performance and if my engine lasts longer that's cool too. Thanks DK (Posted on 5/19/2022)

No more Gunk in my intake Review by Texasguy
After researching the long term effects of an EPA regulated intake, and viewing the gunk that was in the breather tubes; I knew this product was necessary. I purchased the catch can along with the discrete tubing t-connector kit and drilled a 3/8 hole in my intake back plate and chamfered the edges. I ran the tubing behind the pushrod covers and dropped the tubing on the inside of the frame rail near the rear master cylinder. There is a perfect little flat perch along the frame the can sits on. I can empty out after a ride and get a lot of liquid junk that solidifies after a day. I opted for a non powder coated catch can; in terms of finish there was some deep machining marks I had to polish out. For the price I expect a smoother finished piece, likely not an issue with powdercoat finish. (Posted on 5/6/2022)

Nice looking product but it didn't work in my application Review by Willybird
This might work for some people but in my case the fluid that came out of the heads was all condensated water. While the catch cans may trap thicker fluids anything like water will pass right on through and easily escape the can. I do appreciate Dk customs for they're youtube vids letting us know how bad the stuff our $30,000 motorcycles are fire-breathing. I decided to dump this junk under my motorcycle and forgo the can. It's a shame because that little kml e can looked cool. (Posted on 5/5/2022)

Typically DK! Review by prariepilot
The products, in this case the EBS Catch Can, and service are typically DK - the best in the 'cycle parts business! I damaged the EBS Filter and decided to replace it with the catch can. A good choice, given my high-mileage riding. The filter was just too inconvenient to clean, then let dry. I bought a refresh kit along with the Catch Can, so there is no down time due to cleaning. Great product! (Posted on 8/18/2021)

Finally! Review by Shane
I purchased DK's catch can after trying pod filters from Amazon and then another company's can. My bike spits a lot of oil out the breather bolts and DK's can worked perfect!
The other products I tried still leaked oil over my bike but with the design of the DK product I haven't lost a drop of oil on the bike. It contains it exceptionally and I am so pleased. I am in Canada and called to place my order. The customer service is second to none and I cannot stress enough at how pleased I am with the DK Customs and the product they make.
Do not waste your money on a lesser catch can. Buy the best! DK all the way!!! (Posted on 7/26/2021)

Nice and Necessary addition Review by Big Red
I was browsing the site and came across this product. Being an old auto mechanic, I know the importance of fresh cool intake air for good power and efficient combustion. I had tried other external breathers in the past but this one looked well made and I like the fact that there are stages of separation of the oil and air. I am really pleased with this device and am glad I bought it. I am not sure that there is a significant power increase, but I know that I am now introducing only clean fresh cool air into my engine. Thanks! (Posted on 5/11/2021)

Well designed product and nice people. Review by Wezx
This is flat out the best designed motorcycle catch can currently available. It is designed so that oily vapor must go all the way to the bottom of the can by way of a tube and then the air vents by going back up through the filter layers and out of the top of the can. In other words the vapor has a long length of travel before venting which gives the greatest amount of oil filtering of that vapor before leaving the can. Most if not all other motorcycle catch cans have the inlet and vent outlet within very close proximity to each other which can allow the non-filtered vapor to leave through the vents as soon as it enters the can…not good and defeats the whole purpose. Dwayne and Lela were super great to work with, as mine is a custom install and I had certain tolerance and fitment concerns. There were a couple of small problems with my order and they were remedied quickly. Nice people and highly recommended!

Bought this to see how much blowby as my106 S&S stroker uses 1.5qts oil per 2500 miles.
Little blowby but will be great for the new pistons.and rings as only fuel and air will be going in.
I have bought other products from DK. They are great to deal with.

I like this containment can. I can help the EPA do a better job by disposing the billet can contents with my old oil that I take to the auto parts store for disposal.
