I TOOK THE DEFLECTERS OFF THE FRONT OF MINE JUST TO GIVE IT A BIGGER HOLE TO BREATH WITH THE K&N's SOOM IMPROVEMENT BUT NO SIDE EFECTS. I MEET SOMEONE AT A MEET AND EAT THAT TOOK THE BOX's OFF AND PUT ROUND FILTERS ON AND SAID HE HADE NO PROBLEMS. I THINK AS LONG AS YOU DON'T CHANGE THE HEADERS ON THESE BIKES YOUR OK.

I found that about 6, -- 1/2 inch ---diameter holes, is about right.

 

If you go to much, it will decrese engine performance.

 

To prove this, simply Remove the cover, and go for a short ride.

I can tell you that on my 07 RSTD I opened the holes up to about 4" and the bike fell on it's face in the lower RPM'S. This is just my experience. I have read a lot of people's claims have had no problem. maybe just my bad luck. I have BUB slip-on mufflers and K&N filters. no other Mod's. I had to make a plate to cover the large hole and put it back to stock. Good Luck.
