    A must have

    Don't get caught on BLM or Forest Service without these spark arrestors. If they can run a small wooden dowel rod up the silencer it's fines and possible impound. Fires destroy and kill wildlife at the least. Spark arrestors are a responsibility the rider should honor.

    Love FMF Sparky

    Great spark arrestor, easy to install. Be nice to see ad show dimensions as it will fix many models.

    Just what I needed

    The pipe is older and new arrestor was small,but I simply cut a strip of tin formed around to cover (will likely make another more conformed to arrestor)the gap,it made for a good fit,and I dont expect to get fined by ranger for not having one.

    Have a 2001 XR650R that I resurrected from the grave. Full FMF pipe with mystery silencer. Called FMF and they worked with me to identify and confirm which s/a it needed. Good people to work with.
