Now usually removing spark plugs is a two step deal. 1. disconnect spark plug cable 2. unscrew spark plug. Deal done. Not so with 690 Enduro R. It doesn't help that the owners manual doesn't have any instructions on how to change / remove the spark plugs.
The following is a step-by-step instruction on how to remove both of the spark plugs.
1. Disconnect the white coupler from the stick coil and pull the outer stick coil out from the stick coil holder. If the stick coil O-rings are dry, as they probably are, the coils need some force for it to pop out. Grease the O-rings once you you get them out.

At this point you would think that you could insert the spark plug removal tool in to the stick coil holder and simply remove the outer spark plug. Again NO. The bottom end of the stick coil holder is too narrow for the tool to reach the plug at the bottom of the hole! Yes, really. So more stuff to do before getting to the actual spark plugs.
a) You need to pop out the inner stick coil, but since you can't fully remove it this point, leave it in the hole but make sure it is disconnected from the spark plug. (You can feel it pop of the plug). Disconnect the wire from the stick coil too.
b) You need to unscrew the 2 stick coil holder mounting bolts.

3. Lift off the stick coil holder. Dry O-rings may need some convincing again. I recommend applying grease to these O-rings too when you remount the holder.

|Finally! Access to the spark plugs!|
Now You can finally just unscrew the plugs using the spark plug tool included in the toolkit.
