Excellent quality, easy install. Review by 2015Freew
My particular 103 has a lot of oil spray out of these and was all over the engine. I ended up buying DK’s EBS with black can to collect the oil. Awesome setup. (Posted on 10/12/2021)
2007 HD FLHTC 96" TC. Positive review, would definitely recommend. Review by John
Very clean, classy and high polished. Kinda enthused that I won't be burning nasty crankcase/engine oil fumes through my engine anymore. Also matches my other brass accent parts on my bike. .45 cal. shell casing valve stem caps and a brass shifter linkage. (Posted on 5/26/2021)
Easy and worthwhile Review by Matt24
Ran across these from a customer of mine. Looked way too simple to really do anything. I was upgrading his motor to a 114 and after breaking down his motor I was amazed at how clean a 5 year old motor with over 15000 miles were on it. After that I bought for my own bike and told several customers about and they purchased. Folks while very simple I can attest that they truly do work. (Posted on 5/23/2021)
A Must Have!! Review by BIG T
Used a Borescope to look into the combustion chamber area of my 09 Fatboy's 96ci. Was able to get a good look at the top of the piston and there was a considerable amount of carbon present.

Engine is stock and had 15,000 miles when I first looked. I replaced the stock a/c with an Arlen Ness Inverted Big Sucker a/c. I installed the DK Breather bolts at the same time.

I also started using the SEAFoam additive at the same time at 1oz per gallon. Now at 18,000 miles I again used the Borescope to look at the top of the piston. I would estimate a 75% reduction in carbon on top of the piston.

I live in HOT Florida and use 60w Redline oil and have had a very slight oil misting. So slight It is only detected by running my finger across the face of the breather bolts.

I highly recommend these breathers. They not only look good, but they have really cleaned up the combustion chamber on both cylinders. This has got to be helpful in performance and helping my engine last longer.

Great product! DK is an awesome company! (Posted on 4/3/2019)
