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.
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.

The entire system is posted on another review. This catch can set up looks stock, and is appealing. Very happy. (Posted on 2/24/2021) -

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!

Looks good no matter where you put it, does a great job of catching breather blow by. No mess to clean up just empty the can and go, (Posted on 2/17/2021) -

Love it, although depending on where you mount, can be difficult to disassemble. This may become easier with time.

Excellent system to capture blowby from going back into carburetor & capture oil in catch can instead. High quality product from DK custom products. Thanks for great customer service. (Posted on 11/19/2020) -

Excellent choice over the EBS filter option. Catch can all the way! (Posted on 9/15/2020) -

Another great product. Using with stock AC but this is really helpful keeping that hot oil / air out of the engine. I have cleaned it once after a 1000 miles and although not a ton of oil came out, enough to make me glad I have this product. I'm sure the engine appreciates it. :) (Posted on 9/14/2020) -

I called and ordered a custom unit for my bike. I already had some of the required pieces. They helped me with a custom kit. Excellent customer service wish more companies were as good as they are! A real pleasure doing business with them... (Posted on 9/1/2020) -

Quality work! I'm impressed with my entire experience. Yet to see the results, bike is still under construction. Everything I expected (Posted on 7/30/2020) -

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.
Highly recommend.

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. It makes more sense to use the breather can vs. running harmful waste back thru the engine. DK Custom Products has a lot of cool stuff to add to my bike over time. (Posted on 6/4/2020) -

The DK Custom 4 Stage can does exactly as claimed. It totally keeps that nasty oil off the bike. Perfect design! (Posted on 5/28/2020) -

Another DK awesome product. Tried other catch cans. They still "misted" oil all over my chrome. This 4stage catch can completely eliminated that. Best $50 I've spent towards my bike! (Posted on 5/28/2020) -

Even with all slobbering all over my saddlebags I never smelled it until I put this breather on . That being said the bike does run better idles smoother (Posted on 9/4/2019) -

I already had my breathers plumbed to under the bike but it was getting really gunky. This catch can will keep the underside clean. (Posted on 6/3/2019) -

Replaced my air cleaner on a 1998 Dyna Wideglide and decided not to vent the oil from the head breather bolts back into the engine. This catch can allows the oil to be captured and emptied occasionally when needed and it looks great! I purchased the cnc machined aluminum version. (Posted on 3/20/2019) -
