His reply: "I'd be afraid stuff will fly into your engine
As in what flying in the motor?
I really don't know, perhaps a large bird? 
Perhaps after following another "BLING" lowered bike after it scrapes the road and parts fly off.
I guess that is why I am old and stupid now, and have 5 bikes. (I need 2 more to fill out the rest of the week) I really love Orange County and Jessie James bikes I want to take as many pictures of them I can and hang them on the wall,,,,,,,then go ride one of my own bikes and have fun in what ever terrain and bike I am on!

I have said for years now " You don't take a Cadillac mountain climbing or take BIG FOOT monster truck down the interstate”

And yes, I have hit a few birds in my 40 years of motorcycle enthusiasm, I just thought it was not their day!!

"They ani't hard to unstuck even without the K&N's"

See Ya
