    I bought a Akrapovic can for my '02 640 Adventure P/N 57305079400 and was wondering if anyone knew if there was a spark arrestor available for this puppy?

    It has the DB killer in the end but I would also like to keep the USFS happy and not start any fires while having fun. :D

    Any ideas?

    open up the end cap and weld in a bit of screen; can't remember what the grid size requirement is though.

    oh, with Ti you will need to use argon or some such gas as a buffer to keep oxygen out of the welding area since Ti burns!!! (think fireworks... :eek1).

    i know, i know, silly suggestion, but I don't think USFS approved a spark arrestor for the Ah-crap-O-vitch.

    I'm thinkin' that without the U.S.F.S. stamp, all the screen in the world won't help you with a hard-ass Ranger.. :cry

    yeah, the 950 folks are a bit peeved too - because the Akras were a factory option and they are not USFS approved... :huh

    :bluduh

    I can weld in a piece of screen (if someone knows what kind to use) to do the right thing.

    If someone feels like playing hard-ass though all the screen on a submarine won't help me without the stamp.

    NO WELDING!!!


    :eek1

    That's Ti baby - you gotta do some serious stuff in order to weld onto or around that, unless you wanna hold the 4th early this year... most expensive roman candle I ever heard of!

    Maybe just get some kinda fit system, wedge rings or sumpin'. Unless you know a Ti welder that uses isolation gasses.

    Thats because it reacts with the O2 and gets brittle
    Its magnesium that burns... underwater

    soo... whats the core made off *sip* ?
    will a three inch supercrapp end cap fit inside? *sip*
    I figure if you drill and tap six holes on the face of the core. (you know down inside the endcap) you could slapp a stack O' plates and a supercrapp endcap on it and then just put the Akro end unit back on. *sip*
    supercrapp end caps are stamped USFS approved. put enough plates on it won't restrict anything and it is truely a sparky without welding *sip* :1drink

    When riding my plated streetbikes (R90S, Norton, LC4) in the dirt (no USFS stamps) the rangers never hassle. Just my experience.

    My 99 LC4 stock SuperCrapp exhaust does not have a USFS stamp, but it is a streetbike right ?

    Do cars need Spark Arrestors if driven in the national forest ??

    look down inside on the endcap itself. mine is stamped with all the blah blah USFS app stuff.
    I think if your back in the woods.(single track) not just on FS roads they will check even if its plated. :nod

    Steve,

    The OEM "hoover" on my Adventure was USFS stamped as is the IDS2 'Trapp on there now. Your point is well taken about cars. I just like being fully legal. I've seen press releases where it was claimed that a spark from an "off road vehicle" was blamed for setting a fire. I wonder how that was proved (or if it's fabricated out of whole cloth)....

    Funny, I have TIG welded Ti many, many times as a race car fabricator and never had a problem what so ever. I have also welded Mag/ally transaxle housings on Reynard FF2000's. Those you need to be a little careful with but not too bad. Just like ally.

    I'm curous where you got your information from?
