Xrott,
what size motor do you have?
reason I ask is because i've been dealing with the venting issues on my 03 Mastiff (S&S 107) for quite some time. I vent thru the heads with that chrome crossover tube as well as a lower port and I've never been really happy with the results. I don't like all the lines (even though they're braided

) running all around my motor.
Recently, I changed air cleaners to the Doherty Power Pacc and it came with the power vents.
Finally, I am happy with the venting of my motor both functionally and cosmetically. The power vents really clean up the looks of things behind the AC and i've only seen minimal dripping from the vents which I'm more than willing to clean up (trade off).
Additionally, my oil capacity is 3 qts. During my last oil change, I filled the tank with 3 qts then purged the old oil in the crankcase (which wasn't much) by starting the bike with no oil filter until what appears to be new oil comming out. Then I installed my filter and rechecked the oil level. The level wasn't that far from my original mark so I left it there and I believe this also helped in minimizing the 'pukeing' my bike was previously doing.
Even the lower vent line, which i left in place since it's pretty much running along the lower frame rail and is outta site, is clean and no oil spray under the bike!
Sorry for the long post but I thought the AC and oil change trick/info would help you out.
