    I made it all the way to 111 miles to replace the air filter (ride home from the dealership was around 90), and all the way to 318 miles to install the Wings.

    That was the end of March. She now has about 7,300 miles.

    Shortly I'll be checking the valves. There appears to be a lot of tubes and all around the engine. With my Wings exhaust there is on need of some of it so SAS shall go at valve check time. My question is when the SAS is gone and there is no longer a need for a top vent hose from the engine what did you guys do? Did you run a hose terminated to a filter somewhere or block it off completely? Wings web site says they also make one. All other sites that have them only offer for the big twins as far as I can tell. Does blocking it off create excessive pressure in the motor?

    Stupid question time - why only the top hose? Or, asked another way, what is the lower hose for?

    Some people do remove both hoses and install a plate. There was a guy manufacturing them last year. His name on supermotojunkie.com was Oki, and here I believe it's Okipouros. Don't know if he is still doing it.

    I opted to leave the ventilation system intact and only remove everything related to the SAS system. Others have run the vent hoses to a small breather filter and blocked off the return to the airbox. Some only run the crankcase line to an external filter and block off the airbox.

    I haven't read of people having problems no matter which way they went, but that question will probably draw more response on the New and improved KTM690 WUNDERFEST thread.

    Thanks. Which air filter did you put on? Remap?

    I bought 2-both UNI's. One from KTMTwins prior to purchase, and one from KTM post purchase, and rotate them. I prefer the KTM version as it is orange. Easier to see dirt on it than the black one I got from KTMTwins.


    Have not remapped....yet. I am looking into it. I just had the tps' reset as well as the stepper motor adjusted. Waiting to get a good feel for that change.

    Repacking material has arrived:

    Also using this to bolster the holes in the steel wool

    [​IMG]

    Roll the packing around the perforated inner tube and tape it up to compress it to get into the outer casing

    [​IMG]

    Due to the rivets holding the Wings logo on, I used a steel measuring ruler to keep the rolled pig from hanging up. Guide the inner tube into the link pipe

    [​IMG]

    Reassemble and rivet on the end cap

    Remember my insulation band below the hanger strap was burned away?

    [​IMG]

    Meet its replacement:

    And that is it, job done.

    Bill-word to the wise...

    Make sure that steel wool is STAINLESS steel wool. Ferrous steel wool will burn and burns very very hot.

    We used to make our own thermite by burning steel wool, mixing it with aluminum powder, potassium permanganate and kicked it off with a jigger full of glycerin. Fun stuff and the shit would burn right through concrete.:eek1

    Check it with a magnet and try to set fire to it with an open flame to confirm.

    Hello guys,
    I'm Gorazd Marovic, the producer of WINGS exhausts.
    Don't worry the wool is STAINLESS. And don't worry about "iron/mild steel" burning temperature either- it won't burn at all. It can only melt.
    Thermite is the totaly different storry, don't get confused by that.

    Guys,

    I've been talking to Gorazd abut producing a muffler with only stainless steel wool packing instead of fiberglass, which would add a bit of weight, but last much longer. I think the trade-off is worth it us ADVriders who usually put on a lot more miles than racers. It would still be a lot lighter than the stock boat anchor muffler and run just as cool as the regular Wings.

    Would anybody else be interested in a stainless packed version?

    Lukas

    I'll be, for sure. However, will it be quiet enough? Seems that you might struggle to get it packed tightly - but I know nothing about this.

    I'm a little bit skeptical about that (loudnes, heat issue) because steel is heat conductor and e-glass wool is an insulator.

    One of the most important characteristics beside high temperature resistance is also the resistivity against blowing out the fibres. I must make some serious tests with this wool before I can give you my opinion.

    Techmat is a similar product for the same application but rated to 1800 deg. This company uses it:

    http://www.ebay.com/itm/TRX450R-PHO...Parts_Accessories&hash=item4397999d66&vxp=mtr

    The material is available on Ebay:

    http://www.ebay.com/itm/1-2-20-x38-...pt=Race_Car_Parts&hash=item20db85a913&vxp=mtr

    You may be able to find it in good supply better in Europe.

    I've used it in RVs for heat shielding and sound insulation but not yet for motorcycle exhaust.
