Here’s a free mod some may find useful. A relative of the dealer where I got my YFZ let me in on this. For us who ride at the Oregon Dunes (and other places where sound checks are always around the corner), our bikes must pass the 93db level. This is no problem in stock form. But pull the spark arrester out and you’re over 100db easy. Here’s the trick. Replace the stock spark arrester with a late model Raptor spark arrester. All you need is the small, black insert but you may have to buy an entire muffler to get the part you need. I got a used muffler for around $20. The Raptor insert is close to twice the size and allows a lot more airflow for performance. And it’s just slightly louder than stock so the cops should just waive us by.
