06 650i smoking when doing a wheelie

[750kid]

My buddy has a 06 650i that lets out a ton of smoke after like a 50-75 yard wheelie. We tried it on my 07 750 and got nothing. Does anyone else know if theirs smokes after a long distance wheelie? He asked kawasaki what it might be and they told him they all do that then when he told them mine didn't they changed their story and had no explaination. Anyone have any ideas what this might be?

P.S. Dont know if this is where this should be but looked good enough move it if it needs it.

The oil is being sucked up through the crank case vent hose to bottom of your air box. Many machines will do this, but some, like mine, never do.
A dirty air filter will contribute to this as it increases the vaccuum in the area inside the filter where the vent runs to.

Also, check oil level to ensure there is not too much. Be certain to screw the dip stick in all the way when checking it.

Is there a quick way to check to see if this works before we do it just to make sure this is what is causing the smoke? Don't wanna rip it all apart if we don't have to. It sounds kinda the same but his is just a wheelie on land no water added. We'll try anything he wasn't very happy when mine didn't smoke.

Rip it apart??? You simply check the dipstick, thats more simple than taking the seat off.

I know the oils not to full his rear seal is leaking so he has to keep adding. Its usually low.

I wasn't talking to check the oil. I was talking about running the vent pipe from the crank case.

I also was talking land with no water added. Here is a quick visual check. After a smoking wheely, pull the air filter assembly and look in the area under the spark arrester and in the carb inlets. You will see a bunch of oil in it and you will also see about a 1/2" hole in the back right of this area where the vent comes in. Oil in this area means this is the cause.

my bike does the samething. Smoked like heck after a long wheelie..opened the airbox..full of oil

try a one way valve on the vent hose.

Mine will do that on long hill climbs too. After about 6-10 passes on the hill, it quit, but the oil level is still full. Im thinkin that I overfilled just a bit.

Once he gets it back from being serviced were gonna snorkel it and try venting that hose somewhere else
