Better buy extra's

I installed the Big Gun slip on about a year ago on a KLR 650. You probably know that the KLR is not exactly known as a power house motorcycle. That is why I was surprised the spark arrester screen was disintegrating after only about 1000 miles of pretty moderate street riding.
I am not sure what other options there are for a different brand of spark arrestor for a Big Gun, so should probably just plan on keeping a spare handy so you don't get busted by the forest service.

Spark arrestor screen

Installation takes all but 5 mins and from there your legal to ride at ohv parks. It also cuts the sound down a little without taking any power away. Just make sure you put a good thread locker on those bolts when changing out the exhaust cap.

Fits perfect

Spark arrestor installs quickly and easily. If using with a silencer (Big Gun Quiet Core), it will not allow the end cap to seat flush.

A: U.S.F.S. Forestry Approved (Screen Type) Spark Arrestor.

The spark arrestor is compatible with all Big Gun Exhaust Systems.

Also a good idea to pack the purchase order of spark arrestors for when you are out trail riding as a back up document of proof that you are in compliance with the USFS.

A: Unfortunately this spark arrestor is only compatible with Big Gun exhaust systems and will not fit your stock WR250F exhaust. The WR250F stock exhaust is already spark arrested unless it has been modified. if the stock spark arrestor has been removed, a replacement can be purchased from Yamaha through our OEM parts fiche here : http://www.motosport.com/dirtbike/oem-parts/YAMAHA/2007/WR250F/EXHAUST .
