A man would have to be looking for it to see the hose running next to my cylinder... it is outside of the push rod tubes. With the stock AC cover and the lower fairing, it's not somewhere people look at the bike.

Yes, it's there, but I went with black fuel line so it doesn't "stick out"

Well... I see it. But I'm always looking for it. Just a thing I guess.
It's not bad looking though - not that it matters what I think, but you're right. It kinda blends in with it being black and all.

Dig the 43 by the way. Ya'll Doofs be crazy.

Yeah, you see it in the picture, because that's what the picture is of....

But if you ran into me at the bar, you would be noticing a lot of other things first...

Is there a way to vent the stock AC right behind the AC itself instead of running the hose down?

I have found that the gunk flowing out the hoses has a bit of water vapor as well. It creates a kind of vaseline gunk that starts to narrow/clog lines and my catch can had a thick layer.

I still think I came up with one of the best/cleanest looking,invisible mods so far.If I do say so myself.

Copied and pasted my solution from one of the many threads about crankcase breather venting.

Also lots of good info, ideas, and photos in this thread,
https://www.hdforums.com/forum/touri...-included.html

This is what I came up with after being unable to find any system that would work with a SE stage one backplate, I went with dual hoses parallel to bottom of rocker box covers then down to hidden catch can in cowbell. Marine shrink wrap over fittings tapped into backplate really cleaned it up.










This is why. I didn't have a lot of oil drippng, But enough to make a mess on cam cover,pipes,side cover,and front of saddle bags if I didn't clean the filter every week or so. It looks like this because the moisture and oil are being shaken like a paint mixer in the cowbell. Glad this gunk isn't going in my intake.

I believe you are referring to the stock breather channels drilled in the SE back plate.

I squeezed Ultra Black silicone into the holes till they came out in the "chambers" then tamped it down a bit in the chamber to form a type of "head" that couldn't slip back through the hole into the throttle body, just for added insurance. Make sure it's completely cured before using the back plate.

Exactly what I did.
