Pulled the air filter today to get ready for this weekend and there was what looked and smelled like motor oil in the bottom of the air box and the air filter was wet as well. I rolled the thing gently last ride, could this be the cause?

More importantly anything else I should check out? the EFI?

 

I am surely no expert in the EFI world, but seeing alot of roll overs at the MX track you see some oil in the air cleaners if they don't kill when they go over. I am sure there are better experts on here than me but I just tell you what I have seen. The guys that I have seen start their machines back up finish the race, cleaning the filter when they are done.
