Yeah, mine do too, I was more worried about the little things (sand particles etc) that will get kicked up from the road. I intend to ride mine as a daily driver, so I'd like it to last. I'll keep looking into things then, thanks for the info! And we need MORE PICS!! She's a beaut!
If you intend to ride daily, as opposed to track only, those screens only keep rocks out. The fine sand and dust thrown up will pass that screen like it wasn't there. You get to continuously hone your cylinder walls and valve seats. Race engines are frequently torn down and rebuilt, so it is not as much as an issue for a genuine race bike.
There are argument in the automotive forums about whether a K&N filter filters enough of the fine dust out, never mind about a metal screen. A metal screen fine enough to filter out real abrasives would also block and reduce airflow, the exact opposite of what the velocity stack were put on for in the first place.
While these type of setups really look cool, they are non-functional for daily riding, or even seasonal riding. Unless you don't mind excessive engine wear.
