Air Injection.
It is the silver pipes that sit right beside the spark plugs.
You can see them in my video.
The purpose is to burn off impurities for emissions control.
There are kits to remove them and plug the holes.
The result is cooler running engines, less popping on deceleration, and easier access to the spark plugs.
Nicely done ... just wanted to add my thanks, for this and the siphoning video as well. I am planning some wiring and AI removal, and this is invaluable.
what everyone else said. great job. this is the first bike ive owned that has that safety clip and i wasnt sure if it needed to come off or not. thanks so much.
