    Hey, guys!
    I can report that I've possibly discovered the way to solve the problem of oiling the intake port of the front carbureator of ADV 950.
    The solution is:
    1. You need to remove SAS and EPC.
    2. Depress the tube from EPC outlet (taken from any cylinder), You will use it later.
    3. Unscrew the aluminium vent inlet on the airbox (it's hard, but possible - it's not pressed, it's screwed)
    4. Press the EPC tube into the inlet hole (short side into the airbox... Maybe You need to cut off some of the plastic inside, to place the outlet higher over the carb.
    5. Attach the vent hose
    6. Enjoy

    So, it's 2500 km over, and the carb intake is clean (the side of the airbox is little dirty). Looks like it works well.

    Photos are coming soon.
    Hope that helps...

    And more now - 50k km passed.
    I proudly introduce the self-developed oil separator.
    This is the cylinder, which is filled with the metal sponge. The inlet is directly cutted to the inside bottom of cylinder, the outlet has free 2 cm inside the "tank" (this provides turbulence effect). So, the oil loss through the airbox is zero!
    I can provide You the datasheet, or can build this separator and send to anywhere.
    The prototype is machined from stailess steel, and now we use aluminium.
    Also, we have a new version of the separator, which has the outlet on the side of the cylinder - for more turbulence.
    Here is the photo of the mounted and tested device. Looks cute, I think)))

    How about just:

    1, Replace balancer shaft seal
    2, Put a small filter on the end of the vent and route it away from the airbox?

    :)

    (The USA 950's (2004+) don't have an EPC system)

    Mine was smoking out the exhaust , replaced the balance shaft seal and that cured it .

    Shaft seal was replaced, but some oil still goes to the airbox when riding at high RPM (>8k rpm) (in my case). Maybe, I should change the oil type.

    The filter on the vent hose looks quite dirty for me)) But it's simple)))

    Now I'm quite happe with the separator. It's smaller, than Honda solution, which is described on ktm950.info.

    Here is what i did. I put a bit larger oilbreathing filter at the end, so it would not restrict the pulsing flow. It works and there is nothing to it. I have the shaft seal in my garage but wont replace it before winter, as long as this is working;)
