    i really doubt it. I cut mine open to get a straight shot at the cat... and it was still a job. going in from the back, you would be attacking it around a corner.

    I suppose one could do it with proper tools. You can see the floor in the "cat removed" picture where the cat is removed. The problem is that while you could probably/maybe pound out the cat from the rear you might end up with a lot of cat bits rattling inside the exhaust. Although... if the bits are small enough you might be able to vacuum them out.

    Stalling problems with a 2014 and an FMF Q4. Need help.

    Hi, I just got myself a 2014 690 R and installed an FMF Q4 exhaust and removed the emission canister. Since then I have had stalling problems every time I pull the clutch and drop the RPM.

    Has anyone here experienced this and is there a fix for it?

    Thanks
    Elasio

    No, I haven't. Do I need to install a specific one for the FMF? And where Can I do this?
    Thanks

    Twin spark 690s don't talk to TuneECU. You have to go to a dealer for a tune. Try an EVO1 air box lid or drill some holes in your snorkel to let the engine breathe better and get your dealer to install the EVO1 map. That should hopefully cure the stalling.

    Yep skimmed over the 2014 bit. Dealer and evo1 map will sort it out.

    Way late to the party but the letter of the law is to pass the probe test. There is a usfs pdf out there whichexplains it if you search google.

    By the letter of the law I read it as the opposite. Probing means nothing, actual approval/qualification is everything. The guide does provide wiggle room though... "Follow your agency's policies when an unqualified spark arrester system is encountered."

    However, everything I've ever heard about actual encounters leads me to believe that surviving a probe is effective.

    FWIW, I got a wings exhaust with a sparky, though not USFS approved. I'm considering that good.

    My favorite national forests say 'must meet the standard' in their forest orders, referencing 36 CRF 261, which says the same.

    With a stamp and unmodified, you're compliant. Without a stamp, one might assume that it's up to them to prove you are not compliant, or one might assume you have to prove it.

    Cuombajj, Here's some pics I thought might be of interest to yourself and others, following on from posts here…...
    http://advrider.com/index.php?threads/ktm-690-enduro-smc-exhaust-thread.364511/page-51

    Here's the internal sleeve with plumbing and cat inside, it has a thin layer of exhaust packing between it and the outer can which makes it a tight fit. I'm sure this has been the cause of more than a few skin burns and swearing, better of without this in the can…

    Another of the can where it comes apart and rivets together for repacking. I used a 30mm section cut from here then slid inside the main can and welded in place, the end cap slips over this perfectly and rivets hold it securely. The can ends up 30mm shorter but thats no problem. I have done many km with this setup and it has worked well
