    Just did the sas removal and it was pretty easy. Hardest part was to install front cylinder plate. :huh I didn't remove air filter box so I think you better have gynecologist fingers to do this. :rofl
    Screw marked with red arrow were PITA to remove. Did remove all screws of oil tank and push it as forward as it goes (blue arrow).
    Oil return hose were the one that was blocking the most. I wasn't able to see where and how it was attached from the middle to move it further away (yellow arrow).

    I just completed this entire procedure: Canisterectomy, SAS removal w/ block-off plates, resistors to fool the ECU, da woiks. I connected the intakes, using the original fittings and a short length of discarded hose . . . never even tried it with the intake holes blocked with bolts.

    Yes, the front cylinder's block-off plate is a PITA to install. I removed all the bolts that hold both the oil tank and the radiator, so I could moved them out of the way (just enough) to reach both block-off-plates bolts using a u-joint w/socket.

    Also just replaced chain and sprockets, went to a 16T up front.

    The bike is transformed: Better throttle response, yet better control at low speeds, runs smoother. It's a happy bike.

    Thanks for such a great post.

    I'm thinking of doing this mod the next time I rip into the bike for an oil change. I just have a few questions. Will doing this help smooth out my off idle throttle response? How long can i expect it to take to do the mods if I take my time and get it all right the first time? Can someone post links for the block off plates and the electrical connectors needed to do the conversion? Thanks for such a great write up I wouldn't even consider trying this if it weren't for such a great tutorial.

    Excellent write up but it's got me confused (doesn't take much).

    My 2007 990 doesn't have all the canister stuff in the fairing ...... I didn't remove it - and it aint there :huh

    Is this something that's missing from UK bikes?

    I would figure that all Euro bikes would be the same so it should be there. If it's not then someone along the line has removed it. My best guess at least.

    I think it has to do mainly with U.S. spec bikes . Our bikes get cleaned up for Kalifornia so they can weigh more, run worse and actually pollute more so someone can feel better about themselves for having mandated more emissions equipment.:puke2

    Euro bikes don't have canister. You can skip that part and start from SAS removal on Katooms excellent writeup...

    Hello!

    after removing SAS on a euro spec 990 seems that now i 've got a hesitation in 3000-4000 too. In the first post that was due to sas removing or the cannister? Katoom119 can you be a little more spacific (photos if that's possible) what did you to remedy it?

    I understand the cannisterectomy, these bikes will get dumped and then then the can will flood. But other than very minor weight reduction and yes less stuff 'under the hood', I don't get why you'd want to do a SAS removal on a 990 FI. The ECU is set up for it, you have to 'fool' it into not knowing it's gone so nothing changes ECU wise. And as far as I know the SAS is not causal regarding hesitation and/or performance issues for an FI 990 (except sometimes after you do it). The Secondary Air System is an emission control system, yes...what's wrong with that? Seems a responsible thing to do in this day and age as those who enjoy recreating in the great outdoors.

    AFAIK the SAS system is only used during the warm up period. And if you have an after market exhaust it doesn't do any good to have on. I believe the main reason to get rid of SAS is to clean unnecessary plumbing.

    The hesitation on my bike was there when I bought it new from the dealer, so the SAS/Canisterectomy didn't have anything to do with it.

    I did make it a bit better by installing the crossover hose between the rear cylinder/left side plug and the front cylinder/right side plug that I said to remove and replace with bolts.

    That being said, the only way I found to get rid of the hesitation completely was to use TuneECU.


    Yep. I put on a set of Wings and didn't need it so I figured I'd get rid of everything while I was at it. I put the Wings on it because the stock exhaust got so hot I honestly could forsee someone being burned on it very badly. You could feel it radiating off the exhaust cans.

    Thanks for your answer. Since i'm running akra map there's little left to tune through tuneECU. Perhaps it's getting a little rich before revving to higher rpm. I believe when i replace my filter with a cpr like filter i would get more air. Best case would be getting it tuned by a professional but i suspect that there aren't many here in Greece to do such tunings.

    As others already mentioned it SAS is practically useless after replacing stock exhausts. Also by replacing stock exchausts you get rid of the catalytic converter which is also irresponsible. That makes half or more user of adv forum irresponsible and so on.. but that conversation would be trolling on this thread i'm waiting/getting information :rofl :freaky

    I had an Akra map in mine and with TuneECU my tuner went in and just made the Akra map better. I actually got a lot more MPG out of mine.

    Don't know what own source is and after many years of Windows I converted to a Mac and haven't looked back.

    I was just querying you if you would be kind to share your tuned map with the rest of us. :D

    As the story goes open source code (meaning linux, unix etc) are made of people sharing code with each other and have made it to be technologicaly on par with windows without paying for expensive licenses and patterns owned by collosal companies. On the other side windows you still have to pay everything. Same goes to apple and macs.

    Perhaps you've already gave me an answer by pointing out you're an apple user. In that case cheers to you again, no hard feelings whatsoever :freaky:freaky

    I actually don't have the map file but I'll see I I can get it and put it up.
