oil spitting out crank case breather bolts

im not sure if my bike and I belong on this forum considering its far from a chopper, besides the 5 or 6 mods I did to it its pretty much stock. I guess I like all the naked chics, anyway, I posted this on the XL Forum in the E.F.I. section and no bites so I figured I'd give you guys a try. I've got a 2015 883 iron with an after market air cleaner and I've got oil coming out of the filtered breathing bolts(DK customs). I've got about 2800 miles on it and it just started about a couple of hundred miles ago or so(not exactly sure). is this normal for a brand new bike, I ride every day back and forth to work so it doesn't sit around for periods of time. I had a 2014 with the same set up(which I totaled) with 9500 miles on it and it never had this problem. it blows back on the oil tank, air cleaner, up on the gas tank and seat. again is this normal or is something broken like an umbrella valve or check ball(according to some of my research)? rigged up a temporary breather kit with a little filter on the end, essentially a road draft tube which will work until the drag specialties kit comes in. any help would be greatly appreciated, thanks 2015.

Yes.... that seems to be a common problem with the Sportster just like the big twins....they say that the Sportster is sensitive to the amount of oil in your tank..some run it a little low to solve the problem..Can't tell if the Sportster has an optional crankcase vent ..from the pictures it looks like there is one somewhere below the oil pump..if so I would definetely use it...

A little oil coming out of a breather isn't abnormal and even a couple of drops can make a big mess. Make sure that the breather isn't trapping or syphoning oil and causing the problem. As far as your bike being far from a chopper, you've modified it so it's on it's way to being a "chopper"...whatever that is

Of course you belong here. The more the merrier! I would watch the oil level and see if you lower it that it stops pissing oil out the breathers. Also make sure the breathers are clear the more pressure the crankcase the creates the worse it will puke oil. I use a similar stone filter on the crankcase of my hotrod bike and it vents well enough that I dont have any trouble but I vent it from the heads and the crankcase. Its a 113 EVO with .650 lift cam and high compression.

thanks guys, I just checked it on the jiffy stand, sat about ahalf an hour after getting to work so it was still warm and it was 3/4 up the stick. I change the oil on all our vehicles but my wife talked me into the service plan so the dealership does the oil changes on the bike so I guess 3/4 up the stick warm is too much oil?
