In this video I will show you how to remove the plugs, Its better if u remove all fairings because the cylinder 1 and 4 is hard to get to. Remove side fairings then there is a hole that goes through the frame if you can get a slim and long socket extender it would make life easier.
I used the ignition coil removal tool and universal joint socket to make life much easier.
Feel free to ask question about the removal.
