Just did my 6000 km. check, and my air filter looked even worse than the one in the picture, much worse. I bought the bike July 19 with 4100 km. and it had been on a farm for two years. It was definitely a mouse nest. I rode it for 2000 km. like that and, amazingly, it ran well. Unfortunately, I can't figure out how to post the picture for you, since it says we have to upload from a web server. The filter is unbelievable. If someone wants to volunteer to post it, I can e-mail the pic to you.
I've got the new air filter in now and have been riding and it doesn't even make that much difference in performance, though there is some and the bike has a nicer intake sound while opening the throttle.
Definitely do your air filter checks and also check that air filter after a period of storage. I've heard of mice building nests in mufflers and seen recommendations to tape over your muffler ends with duct tape for the winter. You could tape over the air box intake for storage too.
Luckily my place is pretty much mice-free with two cats and a hunting dog.
