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.

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 Machine Cut Aluminum Finish that can be polished to a mirror finish, see at this LINK

Slick Review by Rob
I purchased the billet finish for my 2010 super glide custom but decided to go black on my 09 Electraglide classic since the bike is black and the black catch can with the black hoses and the black clamps look slick. I am very impressed with the quality that DK customs continues to roll off the line. Keep it up guys you’re doing a great job! (Posted on 6/5/2022)

Beautiful sensible design Review by GMR
I’ve got an ‘05 Sportster punched out to 1200, ported the heads, lumpy cams, Super “E” S & S carb. She has always fouled plugs and produced lots of top end sludge. I run a K & N breather and I always figured that sludge being piped into the intake. Three or four years earlier I fabbed from 1/8” tube fittings a dinky drain set-up. No improvement.
An e-Mail from DK mentioned this Catch-All for drool, the concept of cleanable catch basin, multi-stage filtration and a bore size that makes sense. Dwayne the design is brilliant. Mounted with 5/16” nipples soldered into the K & N breather bolts, high pressure fuel hose for stiffness and a “Y” piece I fabbed from 3 hose nipples, brass.
Installed a new Accel coil and with the EBS fitted, this girl has never ever run so clean and strong. (Posted on 5/28/2022)

Incredible Product and Company. Review by Spooks
I was having oil blow-by issues on a 114 M8 Heritage Softail. I installed this and it helped tremendously. I was able to diagnose the blown oil in a lab and found out the oil was getting to hot. I also have a lucky engine with very high compression. So I switched to synthetic Red-Line oil and with the EBS catch can it completely solved my problem.

This extremely well made product completely won me over as a fan of DK Custom. The quality construction is apparent just holding it, and after being mounted for 5k miles and riding through North Dakota hail and a Tennessee hurricane, it looks good as new and is still easy to service.

I got fancy and installed mine on the bottom of a dog bowl style aircleaner and ran the tubing behind the plate. No visible wires. I get lots of compliments... if they even notice it! (Posted on 3/16/2022)

Nice. Review by Noneck
Well made, should do the job nicely. I think it's expensive for what it is, but I couldn't find another catch can this small so I bought it. Aside from that, if DK offered a prefabbed bracket to install it would be great. There are a lot of places to hide these but a simple bolt on install would be nice. I chose to hide mine behind my oil cooler on my 2020 Roadglide so gravity will help the oil to drain into the can. (Posted on 3/14/2022)

Quality product. Simple install. Review by Richard
While researching the addition of a catch can to my 2018 Street Glide Special, I spend a lot of time on YouTube seeing what other people had done to install this product. I ended up going with the installation of the catch can within the airbox but with the lines that would normally feed into the intake being connected to the catch can instead. The fumes that are generated will still be ingested into the engine however the oily mess that was present previously has been eliminated. So if you're concerned about keeping your motorcycle emissions legal, this setup will work for you as it did for me. (Posted on 10/15/2021)

Happy Review by Chuck
I had purchased a outlaw Air cleaner a couple years ago and had the original catch can set up.
Well, things get improved from time to time and although irritated that refresh kits were not available for the original, I purchased the new design. Doesn't need to be cleaned as often.
The one issue I have is I get a little oil mist on my exhaust. More then likely because I have the can right below my air cleaner. ( I like that look) . Right after the install we did the 1000 mile in 24 hours Iron Butt and the rear cylinder exhaust got oil mist on it. ( not terrible) . Of course doing the Ironbutt in 16 hours would suggest that we ran these bikes pretty hard.
Last item. In the 2 plus years I've used this system, I have never had to return this bike. That's at least $500 in dyno time.
Good product. (Posted on 10/1/2021)

So easy Review by Josh L
Finally got sick of wiping oil off the side of my bike. Found this website in a Google search and it seemed like the best option. So far so good! It was fairly easy to install, instructions were pretty good, and it’s working out perfectly so far. I love that the catch can is able to be emptied without disconnecting hoses. (Posted on 9/29/2021)

Reluctant at first but now I'm sold on it. Review by Will
After watching videos and doing some research I decided to order the catch can. The material is solid and well built. I pulled my plugs and using a borascope, I check the piston tops. There was build up as there should be for 57K miles on my 16 Road King Police. I have the over sized breather bucket and had to be creative with the plumbing, but routed the hose down and using some zip ties (for now) mounted on the frame under the transmission. After rising for about 1K miles plus or minus, I once again checked the piston heads. They were a heck of a lot cleaner than before, and the bike is running smoother. I was actually surprised that something as simple as that could make that much difference. (Posted on 9/10/2021)

Very good quality Review by Artorius
Do NOT be tempted by one of the lookalike cheaper and slightly smaller catch cans that are plentiful online - they don't work and you will get a lot of oily gunge coming out of the breather holes all over you or your bike on longer rides. They only have a bit of foam inside which is useless. The DK one has worked perfectly due to the internals. Well worth a bit more money. (Posted on 6/3/2021)

High quality Review by Manchild
As with all of DKs' products that I have used so far, this one is top botch. I got this for my '17 Slim S SE 110. No more oil mixed air going into my intake and motor. By redirecting the PCV from the intake to this can I have seen a noticeable bump in performance as stated. (7% power increase claim) The bike feels it has more torque and the rpms seem to climb faster. Could it be placebo??? sure. But there is no denying that OIL MIXED air is no longer going into my motor. AND THAT alone makes this mod worth doing. Imo. KEEP YOUR MOTOR CLEAN. Stop the carbon build up that is happening by not venting the PCV to a can or atmosphere via filter. GREAT MOD. Thanks again DK (Posted on 8/27/2020)

well made but too small... Review by Rusty
In my opinion it is a well made unit... however, the capacity is too small, requiring cleaning too frequently.

*************
If you are filling up/needing to clean it more than once every 3000-5000 miles you are spitting too much oil.

The video at the following link may help you get it down to a "normal" amount.

Got the catch can to replace the exposed filter on my external breather which was letting some oil make contact with the heads and creating a burnt oil smell.
