Default Screaming Eagle Cone Intake (2008 FXDF)
Hey guys,

I have a quick question for you guys. Ever since I installed this on my Fat Bob I always get oil coming from the air cleaner that falls onto the engine casing (that flat spot). Anyone know how I can stop this?

Thanks!

It's probably just overfilled, however slightly. Take some oil out of the crankcase a few ounces at a time, ride it until hot and check it. Do this until it stops.

I have been running the oil level on the low side.

Maybe not low enough. Can you be more specific, where is the level on the dipstick?

It's on the bottom of the range.

If it's motor oil and you aren't running some sort of external breather setup, that's most likely the culprit. If it's filter oil, the filter is over oiled (which shouldn't cause any problem other than this).

It sounds odd that if the oil is coming from the breather that it isn't being sucked in to the throttle body. If you have enough I guess some would come out but that would make me think you are having scavenging issues at the breather in the head. Some debris in the breather? There is a mod for the head to scavenge better by beveling the breather drain in the head.

It could be exaggerated by the filter/backing plate design. A lot of people with factory emissions breathers get oil inside the filter housing somewhere, but it eventually dries up, evaporates, or gets sucked back in. This filter my allow some of it to pool on the bottom of the filter element, and eventually soak through. I dunno. Also, some engines are just more prone to blowing some oil out the breathers than others. But a motor that does experience blow-by would definitely benefit from an external breather setup, if it doesn't already have one. If the OP is discussing filter oil though, the remedy is even easier. Remove, clean, and re-oil the filter, taking care not to over oil.

After doing some work on another friend's bike, and then some cam work on mine last year, I can tell you that the breather valves/mesh filter in the rocker boxes get pretty nasty. Might be part of it.
