Still not seeing anything by the exhaust port
Could it be under this cover under bike ?
Am I missing something here ?
Thanks everyone
It looks like you don't have the pipes or the pump. The two photos below show the setup on mine. The key ingredient here is the existence of the two metal pipes attaching to cylinder head (1 per side) just inboard of each exhaust pipe. Those pipes supply the air produced by the pump. These pipes are obvious when you get your head down there, you don't have to remove anything to see them.
Here is a close up of one of the metal pipes as it connects to one of the cylinder heads (circled red) and held in place with a hex nut. Some folks have removed both nuts/pipes entirely and all the other gubins associated with the SAS and plugged the hole on each cyclinder head. I left mine in place. If the metal pipes don't exist on your bike then the pump won't exist either and this thread will not apply to your bike.
Here is a picture of the pump and pipe on LHS of my actual bike. You can see the pipe connecting to the cylinder head behind the exhaust (top blue arrow) as referenced in the previous picture. The pipe joins to the rubber hose ((lower blue and purple arrows) coming from the SAS pump (circled red). You can see how the metal pipe has been capped under the rubber pipe, in my case by a small blue "bung"). Simply slip down the rubber pipe (therre is a compressable clip that you release first), put the bung on the exposed metal pipe and in my case, I slid the rubber pipe back over the bung and metal pipe.
