The 3 is simple, if u have a Center stand put it on it and put a jack under the engine. Loosen the two bolts that hold the one side drop jack down 1/2" retighten. You might have th lush down a bit. Do other side next. Have a small ruler, or some type of measuring device. If you drop it too far jack it up and a Light tap with a wood block will drive the tube back down.
