Very common. Most likely it's just that there was too much oil put in during the last service. Most people like to put it all the way up to the full mark and some bikes will puke oil when this is done. Take out a half quart or so and it should be fine. I fill mine up to where it is only half way up between the low and full marks and it solved my issue. Any more and it will puke oil when I ride hard for any distance.

You may need to clean or replace your air filter element. A dirty filter can prevent crankcase ventilation fumes from going through your intake. They condense in your air cleaner and drip out, making a mess.

Just experienced the same issue with my 2015 RGS after a long highway trip. Dealer check it out under warranty and said the air filter reached saturation point and started to drip. Shocked me because my 2003 Road King has the stage 1 SE upgrade and never collected the blow-by like a stock air cleaner. Seems to be pretty normal and if there is no loss of power, crazy noises, or major oil consumption it should be alright. I have read of guys running maxipads in their air cleaners to collect the blow-by and keep it from dripping.:eek: Think I will stick to wiping it down with bug slide! :D

If the oils level is correct it could just be blow back... I'll spare u the science crap, but it does happen, I just rerouted the exhaust from the head vents. So instead of blowing Unburned fuel and oil all over the filter element I have it running to the ground via some vacuum tube... Auto part Engine Fuel line Vehicle Carburetor

I don't know if anyone said this, but did you have the drain holes by the umbrella valves drilled out to 1/8" during the work? It actually sounds like the umbrella valves and the hole not being opened up. This will pretty much cure your problem.

No one ever complains about this in the dead of winter. In the heat of the summertime it is very common. The reason being that the engine just runs hotter in the summer, especially when the ambient temperature is 85, 95 or around 100 degrees. As the oil in the crankcase heats up, it expands, especially if you are cruising at 70 mph. The oil has to go somewhere as it expands and the easiest avenue is out the air cleaner. Try letting the oil on the dipstick be about 5 dots from the top of the stick when it is sitting upright. Resist the temptation to keep adding fresh oil so it is at the first dot (top) of the dipstick.

Karlcin18,
Where did you get the replacement o-rings?

EODHOG,
I bought the bike about 3 months ago and the dealer said that the previous owner had stage 1 completed on it. There is a K&N air filter under the stock cover.
