FE/FC Engine Oil in the Airbox

Hi to All,

Does it ever happen to some of you to see some engine oil in the air box. This oil caming through the hose going to the headcylinder cover ?

Thanks.

Not sure what the issue is, I have same bike and no oil issues. I did have radiator fluid run out the overflow during the first few hours on the bike. Seems to have stopped now that it is broken in.

As an aside, Teambowles, I had the same thing happen on my bike with the radiator overflow and now it's stopped.

As for oil in the airbox, that usually comes from the crankcase vent tube. If the crankcase is being pressurized enough to blow oil/oil vapor up into the airbox in any significant amount, it's because of "blow by", compression gasses escaping past worn rings.

Did you fall??

Usually it'll come thru in a tipover to on side or the other
