Stage 1 Air Cleaner

Well, I revived an old thread to find out what air cleaner to change to after my Stage1 update and got no reply.
I recall Dave stating a certain air cleaner would keep from getting oil dripped on my cases from the crank vent. Does anyone recall which one that would be.

Screamin Eagle and Roland Sands both make air cleaners that don't drip. I have both on my bikes and never had a drop leak out of anywhere. Any of the ones that have the little filter and tubes that go up to your crank vents will drip unless you get one with the glass around it and then you have to make sure you empty it. Seems like it would be a PITA.

Yep, I was having the same issue with oil coming from the air filter (Screaming Eagle). On Dave's advice I picked up an Arlen Ness Big Sucker and absolutely love it. Great call.

Ya, Screamin Eagle does have some oil 'film' coming out, especially if you get the chrome housing behind it, but, nothing a quick wipe won't take care of.

Arlen Ness Big Sucker. They internally (no hoses) route the air passage through the backing late casting to vent at the venturi.

Perhaps others have followed suit since then.... I know mine never leaked or dripped.

The same is true of the SE Heavy Breather, anything that holds the filter away from the throttle body far enough that it doesn't have a strait drop for the drip to fall onto the filter and dribble out onto the engine.

The issue is WHERE the unit delivers the oil vapors to. Most dump the vapors at the opening to the venturi, right behind the filter. Those will leak.

The Arlen Ness model deposits oil vapors deep at the very opening of the throttle body, where suction is strongest and there's no chance of condensed oil leaking into the filter and the eventually out of the air cleaner.

As I stated before.....over oiling a reusable filter can create the same effect of a venting engine. Especially in warm climates.
