there's a way you can remove the original vents right below the top rocker box and drill them. i can't remember the size of bit to use, but someone will surely chime in on this. most people who complain of oil in their air filter are putting in the correct amount of oil when they do an oil change. that's fine if you want mist in your air filter. lower your oil level a little bit and you'll have none of that happening. by the way Keith/firedog, hi neighbor, i live at the edge of lake eufaula near checotah.

 

My bike did this after I did my build, and nothing seemed to help. Finally when I had it dyno tuned by Fuel Moto and they "took out" a couple of degrees of timing it stopped completely.

 

I used the "T" method as well....I was having problems when i ran the bike hard i would get oil mist all over my oil tank from the breather filters I had installed. I couldn't figure out why, until i looked at the underside of one of these breathers and saw a bunch of oil. So what i did was I hooked the "T" up to both of the hoses coming from the heads, then I ran a common hose down the right side of the bike down to the frame rail and all the way back to the rear tire. I then put a rubber 90 degree fitting so when any oil mist/vapor came out it didn't spew out on my tire. No more oil on my oil tank and NO oil inside of my intake! Over time that oil can coat your intake and decrease the quality of air going into your engine

 

The oil pan/bag is separate from the crankcase of these engines. The oil pump pulls oil from the bag and pushes it through the system.
I don't understand how "overfilling" the remote oil bag is going to make more oil blow out of the breather tubes when it takes an oil pump to Bring the oil to the system in the first place.

How?
