2000 M2 has oil in the airbox

[Clearwater M2]

My M2 has a "film" of oil in the air box. I removed the air box to clean it and there is a "oil stain" on the front cylinder "breather hole''. Is their supposed to be oil in the air box as described?

Yep, perfectly normal to have a light film in the air box. In fact my cyclone dripped oil out of the air box on one occasion... Can do a breather re route to end this, but its not really necessary.

Mine does it bad. I would love to stop it from doing it. On long trips it covers the side of my bike and my leg. Is there any instructions on how to do the breather re route?

that might be a bit excessive, your bike have alot of miles on it? Breather reroute instructions are all over the forum, most are specific to XB's but its the same concept. breather mod thread

The old trick that works on tubers is to run with oil level right between the full and low marks. If the oil is all the way to the top mark unless you checked it hot it will blow oil out the vent.
