Alright my friend, the time has come and I have checked the airbox to see, and it was exactly what you were talking about!If you have the time and place while on your travels or sometime after you get home have a look inside your air box. Take out the breather filter and you will likely find that its an oily mess as well as oil inside the air box. This will also be a great time to confirm the condition of the breather filter as they can degrade over time. You likely checked this prior to your trip or the last time you checked your air filter, so I suspect all will be good and therefore no rush to get into it on your travels.
Oil in the box.
The breather filter doesn't look TERRIBLE, but I want to replace it.
On the schematic for the air box it doesn't show it anywhere.
Can I replace that with something else instead?
