I routed some hoses to a tee from my Ness Big Sucker, then to the ground. Will put some sort of a catch device on it this winter as it is embarrassing when I leave someone's driveway with an oil spot under my expensive Harley, simply dark age embarrassing, but it is what it is. You don't want to be routing that crap into the intake runners. Believe me when you take your TB off and look inside, it is gross.
Can't see how running the crank case low helps, tried that, (even drastically low), and still the same result.

Then there's the earlier conversation in this post about the dealer said it, so that's the end of it. LOL! That exchange was pretty funny. Anyways, quick story, I changed out my bars to 14in. apes and had to take my bike to the dealer to get my ABS fluids purged and ECM reset and the dealer says one of your new wheels (23in. front, 18in. rear) is throwing the code because it doesn't have an ABS bearing. The dealer says, "it's the front wheel". "Look, you can see it." And then said, "these are the wrong bearings."
So I called the manufacturer who made my wheels and nearly killed him over the phone for swearing the dealer was an idiot. Then I took it to a private mechanic near Atlanta who found it was the rear wheel with the wrong bearings and it was the rear wheel that was throwing the code. And it truly was. Freaking dealer? Ya ok. Cuz they're special right?

well I can't speak for anyone else, but my '07 Streetglide with a 96", has leaked since I put the heavy breather on four or five years ago…..and it is definitely from the two chrome plugs with the o- rings. Why is it when I had a regular screaming eagle stage one filter (and before that, the stock one if I remember correctly) had a rubber grommet that fit over each breather bolt and directed any blow by back into the throttle body to be burned off, yet the heavy breather doesn't have this?

On the last 300 miles or so of a 2,000 mile trip a few weeks ago---I had this issue with my AN Big Sucker. I've never had this before...but I had never ridden 2,000 miles through the mountains and into Canada and back. The oil was coming out of the mounting poins-----------I went to a local shop, ordered new O-rings and gasket--took everything apart, cleaned all contact areas, even took a pik and cleaned out the threads ....took the same pik and cleaned off the threads on the bolts (yep--had too much loc-tite on)....put it back together, bought a pack of panty liners and put them inside my cover---I haven't had any oil leaking yet. So, I'm not sure if I fixed the problem or if the 2,000 miles at sustained RPMs and drastic temp changes had something to do with it----40s, 50s, back East at 70s (temps) .....also, my oil only reaches 1/2 way on the stick at hot check---I don't run at the top of the stick and I still had this blow by, so overfilling wasn't the issue.
