I just signed up for the Hatfield/Mccoy Dirt Days event on June 22-26.
the website says that a USFS approved spark arrestor is required.
Does my 2004 Yamaha yz 450f come stock with one? or do I have to purchase one???

That's what I thought, have any idea where, what type? etc.?

Let me know any cheap sites you know of.

You may also need to meet a noise level so check that out before you go! The least expensive way to go is get something like the Dubach Racing spark arrestor end cap and quiet insert, or the same deal by Pro Moto Billet.

I have never been checked for sound or for a spark arrestor at the Hatfield McCoys but there is always a first. SparK arrestor I'm good shape but if they check for sound they might get me cause I have the T-4 from pro-ciruit.

I ride the HMTS several times a month and have never been checked for my pass let alone my spark arrestor (that's non-existent). My .02's

I use the Pro Billet unit on my 450f and it works great without any noticable effect on power. I installs very easy and can removed without much effort.
