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)

Catch can Review by John Wayne
Love the look. Build quality is top notch. Only thing is I wish I would have bought the full kit. Thought I could save a little $ and get hoses and fittings elsewhere and it was a pain to track down what I wanted. (Posted on 9/4/2021)

Excellent quality and would recommend to install on any Harley Review by RJ
I am very impressed with the quality of the catch can quality and finish. This was installed on my 2017 FLHXS and very easy to install. I would suggest to have the option to have 1/4 inch ID. (Posted on 8/23/2021)

High quality - easy install Review by Sarge
I ordered the aluminum kit online. Then I found that the black can was available. The next day I called and spoke with a very pleasant and helpful young lady. She intercepted my order before if was shipped and swapped out the can for me, saving me the hassle of returning and reordering the correct part. The catch can was of high quality and the install was easy. I spent a very enjoyable afternoon working on my Road King. (Posted on 7/22/2021)

Eliminates Intake Debris Review by David792
I installed the catch can, replaced my air cleaner and rode 800 miles in two days. After the ride I checked the catch can and saw all the impurities that would have gummed up my filter or went straight into the intake. Amazing results. Highly recommended. (Posted on 7/7/2021)

Great product, well packaged. Very easy install. The finish on black on the can is awesome and blows the filter out of the water and is very well made. (Posted on 6/23/2021)

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)

Excellent product! Review by HogWart
I thought this to be a bit pricey for what it is, but after I received it, I can see why. It is very well made, well engineered, and looks very nice! So nice, I considered hanging it in plain sight (but in the end, I put it underneath the motorcycle). It looks very easy to service - just unscrew the body, and clean it out. Another very nice product from DK. (Posted on 4/22/2021)

Very nice catch can Review by Greg R
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)

4 Stage Black Catch Can Review by Harley Dude
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)

Nipple Review by Dean
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.

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)

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)

Looks to be well made. Review by Bill
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)

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.

quality product Review by Ironman Chris
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)

Nice Product Review by C
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)

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)
