Jake,

I don't see what you couldn't use a really fine net of some sort, that would help with large chunks but not water. The EHS filter can take a few splashes and such. You might want to take some measurements and see what filter of theirs is a close fit and then you can start making the template and hacking up your air box! Just make sure you rejet too, you'll see a nice performance boost. I know I did with my 400, it was like a new quad!

Well, a good place to start would be 1 or 2 sizes up from where your stock settings are at. I'll use my EX as an example. I went from a #138 main to a #142 main and I went from a #38 pilot to a #42 pilot. I also made sure to have some different sizes on hand to and just things if need be. So... You will want to find out your stock settings and go up a little bit. You will want to do this too with a slip on or full system, then you'll really see nice gains. Your local dealer should have the correct jets and they are fairly easy to install. It just takes a little time.
