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.
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

Best mod I’ve done on my bike. Looks real nice when installed. After two weeks I unscrewed it to check and there was nasty brownish oily water there that would have otherwise been ingested by the engine. Keeping the junk that enters the engine to a minimum is really helpful when trying to get high reliable mileage on any bike. (Posted on 2/1/2021) -

Always been a fan of catch cans, relieved to find this product that includes all the hardware necessary to attach to your bike. Plan on emptying the can on each oil change. It is comforting to know only clean cool air entering the engine AND your air filter will stay cleaner much longer. (Posted on 10/27/2020) -

Catch can works as advertised. The blachkblends in with the bike and is not even noticeable.

Make the nipple the same size as the small hose to get rid of the ugly adapter hose
********************************
We wish we could do that. Over 75% of the folks using the Catch-Can use larger hose that fits the Catch-Can nipple.

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) -

The catch can is made with high Quality in mind and blends extremely well with the looks of the bike. I can even feel a difference in performance when accelerating. I don't have oil spitting down the motor and crossover pipe any longer. I am very happy with the results and will recommend to everyone! (Posted on 8/16/2020) -

Picked the black can to hide under floorboard. After 300 miles I opened it up. Sure enough there was breather oil in the can and not on the air filter. Used JB Weld to plug holes in backer plate. Working great. (Posted on 8/6/2020) -

Nice product, works as explained, love it. Thanks! (Posted on 8/6/2020) -

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.

Works as expected.High quality construction. The ribs around the bowl act to slow down the oil film from forming droplets at the bottom. You can see when it needs cleaning before that happens.It serves as a "time to clean" indicator,great idea. (Posted on 6/8/2020) -

Very nice product. Quality machine work, But finish not that tough. I really couldn't believe that I could feel a difference how the bike ran. Big Question would I buy this again. YES (Posted on 4/30/2020) -

Great product, does what it says it does. Good finish on it, don’t mind having it standout on the side of the bike, not some ugly piece I had to tuck away under the bike (Posted on 11/5/2019) -

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.
Installation was simple and its barely noticeable located behind the horn cover. Hopefully this stops the smell and I continue to enjoy the performance bump with this style breather vs the HD routing back into intake style but with no mess. :) (Posted on 10/25/2019) -

Use with J&P external crossover and about 3" of fuel line. Attached with black tywraps. Looks great and works better. No spray or leaks. Much better quality and pricing than others on the market. Highly recommend. (Posted on 10/1/2019) -

I've used another brand before, but still got a little messy. This one works perfect. Great product, my brother and dad are both plan to get this style for their bikes too now. (Posted on 8/24/2019) -

Have to love that CNC, they do great work. This a smart looking, well built and functional product. Some delay in receiving goods due to USA weather but communication on this was great. Pity the weak AUD makes purchases and freight to Australia dear. keep up the good work, thanks (Posted on 8/10/2019) -

I originally had the small catch can on my '17 M8 Ultra. I went with this one and no longer have oil on the pipes, saddle bag, seat and my pants. Easy install, works like a charm! (Posted on 7/16/2019) -

This catch can has been great. No more oil on my bike or jeans. This is super easy to install and has been one of the best investments for my bike. Its super easy to unscrew and dump out and I will definitely do the breather kit with the catch can on any future bikes. (Posted on 6/4/2019) -

I had the old style can which was smaller. This can holds a lot more and does not mist on the right side of my bike. The internals are much better than anything else on the market to keep the oil in the can. Great job by DK (Posted on 4/23/2019) -

Installed this on my crankcase breather hose off my oil pump on a 1971 FLH Shovelhead. A little large but excellent quality nonetheless. (Posted on 4/9/2019) -

This catch works great. Nothing but water leaves the can. No oily mess. All of the misty oil stays in the can. Great product. DK customs rocks (Posted on 2/10/2019)
