Catch Can Issue

Anybody venting M8s to ground?
Thanks
Pauly

I am venting my `19 M8 to the ground.

When it was the OEM setup I would see some oil in the air cleaner, but since I routed an open-ended hose to ground I don`t see any oil on the end of the hose at all.

I have about 3 bucks invested in my overboard breather setup.

When you add a catch can, you are creating a place for condensation to form.

If you just route an open hose away from the rear tire, the warm vapors will simply go to the atmosphere.

I'm reluctant about even posting my setup for a twincam, I use the kuryaykn bluegrass fittings from my heads which goes upward to a Y, goes straight over the rear rocker box down to this position. I did this several years ago for a test and thousands of miles later it's still there, I use to check it often but now I just pull the white vaccumn cap on the bottom of container to empty.  I have had a hose on the bottom fitting too but I prefer just to empty now on occasion. It could stand some refinement.

I'm not a fan of going up with drain tubes, but a lot of people do it with seemingly no problems.
TN, when you pull the breathers out of the head at the backing plate for the throttle body, do you have any fluid collected there?
I do like the can mounted in a hidden spot behind the bag.

Hoss, I'm just a parts changer, but this system works for me. It's a vent not a drain is how it was explained to me, and on a healthy motor it shouldn't be a problem. I've taking off the lower rocker box part several times to inspect and the breather galleys were perfect. One time on the breather bolts I saw a little white goo but very minimal, most times when I do ride she gets up to full operating temp.

I've had this system on for some time now, I could look at my notes to be exact. I do live in a hot humid place and my bike stays in a conditioned garage. It did get cool last week. I looked for a pic on my phone but saw a squirrel LOL

I use the stock bolts & breather tubes, slipped into thin silicone hoses to a T, then up along the backbone, then down/out to atmosphere.

Boom. To the ground.

Catch cans are for the track and I don't see the benefit for street use.

My catch can that I bought off Amazon. This one has a dipstick. I was blowing oil down the side of my bike. Tried venting to the ground, but too much oil was dripping. I hope to be doing a 124 upgrade later this year.

Old EVO setup. Seems to work okay...to ground.
