    Glad I found this thread. Thanks to all.

    Removing the SAS has no effect on how hot the exhaust runs. It just makes the catalytic converter get up to operating temperature quicker. The SAS valve should only be open when the bike is first started so if the SAS was your noise it should only be doing it when first started. If you want to test if the SAS is the source of your noise then a couple of locking needle nose pliers to block the hoses to the heads or one needle nose on the hose going from the valve to the air box. You cant just unplug the valve to test because it is designed to be open and flowing unless voltage is applied.

    Yes I've since thought about it, the sas is designed to bring 02 in to burn un burnt fuel...not cool things. But many here say the persistent off idle noise goes away with the delete. It does not explain the specific source... just the apparent cure. That's why I asked specifically where it originates from, sas valve, reeds, and top end noise travellng to air box via the hose, were all suggested. There appears to be no clear consensus.

    The noise I here sounds the same in jane73's video

    That's why you should do some testing. I don't have the SAS installed but I also can't hear anything except engine noise in that video

    Yep.. there's a few very clear rattles. Most noticeable at about 23-24 seconds into the recording. Last week i was taking a gravel training course and i should have recorded that.. Was doing lots of low speed crawling and working with throttle and clutch etc. Sounded like the engine was falling appart.

    Waiting for customs to clear the package so hopefully i'll have the rottweiler kit next week.

    Yup only at low speed or with small throttle blips, and always, just off idle but it doesn't last long either. It seems every time you come off idle, then it quickly fades. It's also very noticable if you listen under the front fender. It appers to be just behind the rad. Looking forward to seeing if you found the fix.

    The only way to make the ticking noise go away is to shut off the engine

    If you do find a SAS block off kit that makes the engine quiet I will for sure get rid of the one I have installed

    When you describe it as a ticking noice I suspect were not talking about the same thing. Ticking valves I have no issues with.

    Hi, I have the same noise on my 1290S, do you have an update after fitting the SAS delete kit. Did the noise you describe go away?

    I had a service scheduled for last week so I've been waiting for that. Now I just need to find some time.. planning to do it this coming weekend. I also found this conversation I had with Rottweiler last year when I asked about the noice. Their reply:

    "Yes, it is the SAS system opening and closing. An emissions kit will get rid of that."

    But I'll now for sure soon. I'll post an update when done.

    Sorry guys it took my a while to get this done. But.. today I did it. The SAS is finally gone (used Rottweiler stage 2 kit). I took the bike out for a 20 minute run and never noticed the sound. I used to hear it as soon as the engine was a bit warm and running low rpm's. I will update the thread again when I have done some more testing. Here's a new movie where the noice is gone.

    Wear earplugs, enjoy the ride!

    SAS does make a few funny noises but not alarming noises and not worth deleting just for that.

    Also SAS has no cannister. It is the exhaust air injection/induction system. Evap emissions cannister is a TOTALLY separate, independent system for capturing/recycling fuel vapors. You can delete all or part of either system independently although most people do both together. If you leave the solenoids in place and plug the SAS spigots there is no cost - or you can buy blanking plates and/or dongles with resistors to fool the system into thinking the solenoids are still connected.

    Who the heck wants to ride around with their head under the front fender? Sit on the seat with a helmet and some decent ear plugs and you will never worry about the funny noises again. As a former early-oilhead owner, I never worried about them anyway.
