Customer Reviews

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)
