    Of course, I can no longer find the post that I recall explained it, only references to it. I also failed to mention that previously I had removed the secondary butterflies.

    I talked to my tuner yesterday. The different stacks didn't illicit a reaction although he did say that he could have fixed my issue on a stock bike. His only concern was achieving a good result without the secondary butterflies.

    So when I meet up with him next week, I'll bring both stacks and the secondary butterflies just in case.

    For the time being, I'm enjoying the bikes behavior at lower RPMs. Can't say if it's making the same power up as I feel the added induction noise would be influence my opinion. The dyno results will be interesting.

    Carbs out in less than 15min with out taking the tanks off...I love this mod:)

    I have pointed the cab boot clamps toward the rear wheel last time I'm was installing the carbs.

    Here is the evidence:!

    I forgot to mention I have flipped both lower boot clamps to maje them accessible from the sides with a 6mm socket:

    Great thread. Just stumbled onto it.

    My 06 990 Adv has SAS in place and turned on, no charcoal canister, Tune ECU Akra map, secondary butterflies removed, G2 throttle cam and stock air box.
    Fairly happy with how it runs but it could be less jerky on off.

    My 950 with Rott air filter is silky smooth.

    For those that have a 990 and fitted a SW filter, what do you do with the SAS stuff. Or is there a better map that I can load up, then ditch the SAS and put the blanking plates on.

    Cheers !

    Just pulled the trigger on one of these. Will be one of those "winter projects" I can do while freezing my ass off in my garage. I plan to use this along with the other guy's "Dog House" and "Snap-out" quick release system for the glove box. I saw those at the KTM Rally this year and they seem like a good idea (since every square inch of storage space on my 990 is precious).

    Yep. :D

    Used TuneECU to put the 2007 AKRA in my 2007 and turned O2 sensors on. Butt dyno says it pulls much stronger everywhere. No mileage figures yet for this map.

    I also built a 2007 2008 map from Power-Tripp's 2009 and later fuel/ignition tables. ECU changes preclude using later maps on earlier motors. I will test it next.

    BTW Doctor_big, no gas smell on my hands after these jetting changes. 990's rock. :rofl

    SAS is used only during warm up to provide O2 to help heat the CAT's which you probably don't have since you are running the Akra map. As soon as the O2 sensors are up to proper temperature (if they are on -- by default the Akra map has them off but that can be changed), then the ECU switches to closed loop mode using those sensors to adjust the mixture. After switching to closed loop mode, the SAS valve stays closed. Most people find that keeping the O2 sensors on gives better mileage.

    Most 990 owners replace the stock mufflers to get rid of the heat of the CAT. Not having a CAT means you don't need SAS so they take it off. If you run SW's filter you have to find a place to mount the SAS valve if you don't take it off.

    Thanks for that info DirtJack.
    I would be really interested to hear how you go with that map your playing with. I have read good things about the Powertripp ones.
    I think I tried my Akra map with o2 sencor turned off but it didnt run as nice. I would have to check to see if the SAS is on or off. Im thinking on because I can hear the solinoid clicking when reving the motor. No Cats on mine. Perhaps I should try turning the SAS off.
    Good luck with the map !!

    Anyone else here having unstable idle issue with #45 jets ?

    My bike runs well when cold but when it warms up well in a warm day, idle goes up to 2000rpm or so or comes down bellow 1400. Its impossible to keep it at 1400.

    I checked the float levels as it was suggested here (see my original post:http://advrider.com/forums/showthread.php?p=21920674#post21920674) . They were a bit off, I set them to exactly 4mm. It got better but still not stable.

    I had this issue couple of years ago with H2W jet kit when I put #45 jets in. I replaced it with stock 42 and it became OK. But 45 is recommended here.

    I also have lots of popping on deceleration.

    Here is my setup :
    170/172 mains
    45
    Factory pro Ti needles on 3rd clip
    Floats at 4mm
    FMF pipes, SAS removed.
    Have FlexJet IMS


    Any thoughts?

    Swap back down to 42's or drop the needle back to 2... Depending on how high in the rpms that the over rich condition goes. Likely by the way it sounds, I'd drop to the 42 first. Also, for 45's, those are too big of mains imho. I like 163/165 with 45's. Might want to drop there first to see if it makes much difference on the low circuit. It will, though probably not enough. Those are good mains however, for running 42's in my experience.

    Every 950 is different. Be patient.

    G ....thx man I will try thrm all. Good thing I can take the carbs out in 15min:D

    Do you think its because idle is too rich? Turning in the idle mixture doesn't solve the issue.

    Think of the fuel screws as fine adjustment.

    Frequently asked and answered questions. My inbox is getting pounded with these and I thought it would be a good idea to put the answers out in this thread.

    I want to clear up some misconceptions regarding the SW7 product.

    "Copycat Design?"

    The basic baseplate design to utilize an ITG style filter has been around for quite some time. So, in essence, we're all copycats. It was popularized in club and professional road and dirt track racing, various Porsche enthusiast circles, and by experimental aircraft folks.
    An example would be Coast Fabrication, a great outfit which has been selling these type of baseplates for many years for numerous applications. The remarkable innovation in the SW7 system is the patent pending sealing method utilizing space-age, custom molded polymer grommets, rather than inexpensive o-rings.

    We spec an aviation quality aluminum alloy baseplate for this application due to it's remarkable anti-corrosive properties and fatigue resistance. The plate is precision cut to our CNC specs utilizing a 4000 watt Amada Gemini CO2 laser. The baseplates are then moved into a HAAS CNC milling machine for final machining. The finished baseplate is then hard anodized to a classified milspec. It's bombproof.


    "Aluminum heatsoaks!"

    Recent misconceptions regarding aluminum baseplate "heatsoak" is non-sensical in this application. The aluminum baseplate weighs under 100 grams, and dumps heat remarkably fast. It heats quickly, but cools quickly. It's one of the fantastic material qualities of aluminum. If the baseplate were required to be significantly more massive, say, for a turbocharged V8 intake plenum, then the mass of the material would be significant, and we'd spec an autoclaved carbon fiber composite.


    "Why not a injection molded baseplate?"

    It's heavier, not thermally stable, retains heat longer, and in our opinion, perhaps not the most economical and best solution for the application. Our engineering analysis lead us back to aluminum alloys after consulting experts in metalurgy, materials science and thermodynamics and after exploring various composite options.


    "Garage Shop?"

    Hardly. SW7 is uniqely located in the Technology Corridor of North Carolina. We utilize the most sophisticated, multi-million dollar equipment available on the planet, not antiques. We have hundreds of kits out in the market, and not a single failure or return. We're convinced that our product is not only the least expensive on the market, but the best one on the market. Period.


    "How come your product is sigificantly less expensive than your competitors?"

    Because we're smart enough to not to have to carry the burden of huge shop overhead, and can take advantage of precision equipment at low cost, we pass the savings and expertly crafted products to you, our customer.

    We don't bother with stenciling our name on the ITG filter, applying decals, or engraving our product. It just adds cost. We are motorcycle enthusiasts, like you. We believe you deserve the finest product at the lowest cost. Why spend more?


    "Jetting Experts?"

    SW7 has spent literally hundreds of hours working with jetting manufacturers to help design a product that works on the carbureted LC8's in the 'real world'. We're here to help your LC8 run like KTM never could.

    Well after several thousand miles over the summer i gotta say this is the best mod i have done to the bike second to suspension rework. I have decided i am going to give the 50 IAJ's a try again and drop my needle and see where i land. Current setup is 99% what i want, but when stone cold the bike can be a bit of a PITA to start even with enricher's. Have a ever so barely noticeable surge when cruising, i mean i can barley feel it.

    I bet based on your EXPERT testing if i drop down to 50 IAJ's and change needles to slot 4 (possibly 3) instead of slot 5 i will fix those two issues.

    Current Setup (Aggressive Street Sport Riding):
    FMF cans
    Part Factory Pro kit and Part H2W kit for my jetting
    Main Jets 170R / 168F
    Pilot Jet #45
    Needles Factory Pro Ti needle 5 position from top
    IMS screws 2.5 turns (Flex-Jet installed for easy adjustment)
    Air Jet #70 as supplied by H2W to replace stock #50
    Float Height 3.5MM
