A local state park requires spark arrestors on any motorized vehicle and I was wondering how much of a performance loss are we talking about if I install an FMF spark arrestor. I have a restored 1981 YZ125H.

I would say very little as long as you keep the screen clean and your jetting/mix is spot on.
