I removed the AIS
on my 2013. I got a baron's kit for it. made it very simple.
You will need to partially remove stuff on the left side of the engine so you can get in to the rear cylinder where you have to bolt that cover plate on. I am not sure what that IS on the left side, apposite my air cleaner lol but I just loosened it up and pushed it aside so I could get to the place that needed the cover plate. Bike will run well and no backfiring once you get that done.
