    I'm just about to pull the Wings unit apart on my 690 for a repack and was also wondering what kit to replace the packing with.

    I did my XR650R FMF with a dedicated Moose kit, but can't find anything specific for the Wings :ear

    How many miles do you have on it?

    I've read of others using a very fine stainless steel wool (grade 00 or so)successfully, slightly louder than fiberglass packing but it won't burn out again.

    Excellent. Can you tell us how many miles you put on it and also please photograph what the used packing looks like after disassembly.

    A previous poster mentioned using rivnuts instead of re-riveting after the pack. Not sure if they would unscrew with vibration but with a little locktite could be solid solution. We need a guinea pig!

    I love the way the apex looks but it was too freakin loud for me. I had it on for <50 miles before selling it. You can literally hear it 2 to 3 blocks away. Happy with my akro!

    Before and after

    IMO the Apex is too slim, and it hangs too low and at a weird angle on the 690.

    The Akrapovic and Wings are the perfect shape, and look even better with the darker carbon fiber heat shields!! :tb:clap

    Bought mine used from an inmate. The price was right. She's a hair loud but that's ok. I may try to fab a "screen/spark arrester" of some sort for the end.

    So far no re-map...I'll know better after Saturday if I need it.

    You can get the repack kit and spare parts directly from Wings, just send Gorazd an e-mail and ask for the price list: http://www.wings.si/ver3/index.html?page=contact

    Dunno if that makes any sense money-wise to get it shipped over there, though

    Update: After more riding I'm getting a backfire once in a while and some stalling at initial throttle opening. Does it sound like remap time to others with this pipe?

    Same thing here except no backfire. I did the throttle re-calibration. Haven't ridden it yet. Just ordered a tuneEcu cable so I can load the Akra or Evo1 maps if needed.

    Big Gun sells a nice repack kit in different lengths, I think it woe work on any repackable can.

    Just curious as to whether you opened your Wings up, and how it looked?

    I'm repacking mine this coming week sometime. Only 9000km, but I rally the bike and it was drowned in a river crossing. When I got it running, I ran it for another 1200km to finish the rallye. That stuffed up the packing. I'm planning on using the 1st available repacking kit that I find in the bike shop. Don't see any reason to stress about it, I've repacked dozens of pipes and don't feel this will be different.

    Easiest to way that you need to repack is when the sticker/logo discolours. Or, like in my case, the rubber band below the bracket melts...

    [​IMG]

    So, I drilled out the rivets holding the end cap and removed the trim band.

    And pull out the end cap

    Time to inspect the packing, At first glance it looks OK, but as I saw the melted strap, I knew it was poked. In fact. there appears to be a hole exactly where the hotspot was

    [​IMG]

    Closer inspection shows the alternative pathway for the hot gasses

    [​IMG]

    So, pulled out the old stuffing. Rather good quality packing, 4 layers. There is some definite burned stuffing

    The steel wool layer has a hole exactly where the hot spot originated. I feel at this point that the packing failure originated from the point rather than from running the exhaust wet. In any case, the end result is the same

    I've ordered the packing. Should be here by the end of the week (I live in the middle of nowhere). I'll show the rest then.

    (ImageShack is stuffing me around wrt image size, making some images are massive, some normal, sorry)

    Is it advisable to get through the break in period before replacing the exhaust and air filter? Or does it not matter?

    If it's properly mapped and you follow the break-in guidelines I see no reason to wait to make mods.
