Crankcase steam hose
 

I just purchased a 2005 FSE 450. I's like new and the owner just had it serviced. There is oil coming out of my air filter box. It looks like it's coming out of the crankcase steam hose. Is this normal?

Welcome to the site.
I did a search for "airbox" in the 4 stroke engine forum and found this:

Thanks for the help Brian. Making the hose longer sounds like a good idea.
Thanks again, Alan

I've been running this solution for 25 hours now, it works pretty good. Occasionally I hear the slurping sound from the airbox, and I then now that it is time to drain the lowest part of the hose. As of now, I only disconnect the hose from the airbox, and let it drain. I have plans to mount a T-connector to the lowest part of the steam hose, with a piece of hose with a plug at the other end. All I would need to do once in a while is remove the plug and let it drain.

Hi!
I had trouble with oil in airbox. GasGas tell me that the hose must be placed in the conection on the frame ( near the oil tank and under the gas tank) and the "free" space filled with foam. Steam goes out, foam hold the oil and the excess come back to the crankcase. I´m running that way last 6 months, no oil leak.

Pic's please. What year is your FSE?

It´s a 2004FSE. I will take pictures on sunday.
The frame have a "chamber" in a triangle shape near the oil stick, I filled with foam and conect the hose at the steel conection just below ( thats the factory project, the hose going to the air filter is a dealer/assembler mod)

That looks like the way it should be done. The motor oil then can recycle. Saves your oil and keeps throttle body and air filter clean.
I don't believe I have that connection to my frame oil reservoir though. Anyone else have this return oil connection on their '05 and newer FSE's?
