That it fits on my 2017 Superlow 1200T
The bolts was too short . I need another bolt that's is longer. An inch longer.Can someone contact me? Please it's about the 2 bolts I have are too short. Do you have them that are longer it should be about 1.5 inch to 2. Inches. To be able to go through the the breather the bolt is hollow and has a hose fitting on the end. But this one is way too short.

Works
I bought them to do some custom stuff (long story, but it ends with me cutting these in half to make something for my Harley). But needless to say, the threads are right and they are indeed longer.Its a bolt with a hole through it. It is what is advertised.

Perfect fit. Just what I needed.
I was looking to make a breather bypass with a catch can. Youtube videos showed people drilling and tapping into their backing plate. Replacing the breather bolts with these did the same thing with no drilling and is reversable.

Worked for me
I have a 02 dyna low with a Arlen Ness air cleaner. These bolts worked great, I did have to grind the ring around it down because my bolts are recessed into the air cleaner, but there the right threads and fit perfect. Now I just gotta get some tubing to route down the frame and keep that nasty oil out of my jugs

Product as described
The product works as described. However, be sure to clean the threads inside the bike of any oil. I would also suggest adding a drop of blue loctite. I had mine back out after 20 miles. And after reading some fourms it's common

Not 88B
This product does not fit twin cam 88B. Diameter is too large and is shorter in length.

Fit 1200 Sportster !
These breathers fit my 2004 EVO 1200 , Almost perfect! I bought them knowing they were a bit too long so, I shorten them up, maybe 1/4” and they fit and work beautifully!
