    Good morning beast riders, what Usfs approved spark arrestors are you guys using on your 800+cc bikes? I have a Yoshimura R77 Carbon on my Harley Dirtster but Rottweiler Performance recommends against an insert due to the increased heat. I hate the Supertrapps but most of the spark arrestors are for 650cc and less. 54mm is the ID of my pipe. Thanks in advance

    I had a Sparky spark arrestor on my old Buell. Comes in various diameters and took a bit of fiddling with it to fit and stay on. Didn't seem to have any adverse effects on the 1200 cc motor.

    It's the silver tin can thing on the bottom (Uly muffler location).

    I'm guessing Home Depot or somewhere similar. It's been way too many years since I worked with these things to recall all the details (and they've probably changed since then anyway) but I'm kinda doubting screens for a drain are USFS approved as spark arrestors.

    There are those that say they are, there are those that are stamped that are/aren't and there are those situations that get a Federal summons to appear in court. Don't get caught DAMHIK. Barney Fife usually doesn't give a poop and is responding to noise, trespass complaints or there for some other good reason. Judges are fond of using incidents like this to pass max fines.. http://www.wlfalwaysremember.org/incident-lists/156-tanker-123.html fire reported started by a tourist that pulled over in high grass in a jeep to take pictures.

    Sounds like that fire was started by the hot catalytic convertor, and not by glowing carbon particles and no spark arrester would have prevented that...

    Don’t get me wrong, that’s still serious, but has nothing to do with spark arrestors.

    If you want a spark arrestor that is legal, all you need is the USFS APPROVED stamp on the end of the pipe and you will probably pass an inspection. If you want a spark arrestor that works, a screen will do that. A screen with the approval stamped on it somewhere would be the best bet either way.
    I have no doubt there are different designs that have approval but the screen is well known and is effective.
