engine breather hose

Hey Guys and Gals,
I happened to go off the trail into a ravine where my bike fell on it's right side. By the time I checked all my body parts and got into the bushes where my bike was, and then struggling with it, it had been laying on it's side for about 10 minutes or so. Of course by the time I got back to the truck I was drenched in oil splatter that had dripped out of the airbox. I assume to rocker breather had drained oil into the airbox and saturated the airfilter and everything else in there. Is there anyway to avoid this? (besides not falling) I thought about removing the breather hose from the airbox and installing one of those mini airfilters. What about stuffing some coarse airfilter foam into the breather hose? I was thinking it would slow the oil flow and still allow the breather to breath. Or will it get clogged and cause problems?

just try not to lay it down. It doesn't hurt anything so I just ignore it. Its made that way for reason so the intake will cause a vacuum on the engine.

It does get annoying when it blows oil out but oh well. I know some people do plug it with a filter and something similar but Uptite told me not to so I left it.

I'm not sure what the limit is, but in 10 minutes alot of oil can drain out ... If you do a search here, many re-route this hose and add some sort of filters to the end of the hose ...

I do not like draining oil out of my engine when it is < 2L total ...

This shows a filter installed on the line ... I'd like to have mine turned up I think so that maybe no so much oil would run out ...

You will still llose some oil if you drop it on its side, but at least its not getting sucked into the engine:

Just got done wiping out the airbox and degreasing my swingarm. I like the the small filter mod.

After I got it home I noticed the oil level in the sight window was lower.

I haven't got the point of dropping the bike yet,but let me see if I've got this right.If you drop the bike on it's right side and it's facing somewhat downhill the crankcase will unload it's oil through the valve cover vent via the airbox through an intake tube?How about a a check valve,sorta like the ones on gas tanks that vent unless there dumped upside down?Doesn' t a PVC valve work something like that?

I'm not sure about the PCV valve but I was thinking about the same thing ...

The easiest way I have found to not dump mine on the right (wrong) side is not to ride it

I'm not skilled enough to choose which side I crash on either. All I know is that my riding pants are permanently stained with little black spots now.

I'm not sure but I think the valve cover breather breathes in and out on acceleration and deceleration, which would not work with a one way valve.

I cleaned for 3hrs on my bike today because of a couple fail overs ... It seems a little oil in the air box goes a long ways as it drips off...
