I have also heard of drilling a ¼ inch hole through the center of the spark arrester to improve performance. Is this something I should try?

NO, it will no longer be a spark arrester and will sound obnoxious. Repack the silencer if needed to gain some performance back.

I'd like to have word with the guy that told you to drill a hole in spark arrester, where would the performance come from?

DO NOT DRILL repack it if you have too, or check out the FMF silencer, now thats performance.

I thought this sounded "off the wall" and therefore, wanted to get a response from KDX riders. Thanks for your advice! Mark
