The tough part of plug #1 is getting the boot out...it wants to hit the air box, there is only one small gap between the air box and frame where it will go to provide the clearance you need to get it out without snapping it off! If you don't have small hands, find someone who does for getting to #1.
The best tip I've found in years was in an Haynes Manual.
Get a small length of plastic tubing about the length of the spark plug tool that is a tight push fit on the porcelain end of the plug, once you loosen the plug sufficiently you push the tubing over the end and undo it and pull it out from the well.
The best part comes when reinstalling, you put the tubing on the plug and you can easily feed it in and line it up with the hole. Do the plug up as much as you can by hand this way you can feel if it is cross threaded.
Once you feel it bottom, remove the tube and use the tool to tighten to the correct specification.
