Following the manual will be the easiest way to do it, so go find one. It gives you instructions on tightening the bolts as this is VERY key in getting it on right and not having any leaks.
When you're pulling it off, you may need to tap it with a mallet or piece of wood in order to pop it off. BE GENTLE.
Putting it back on, it's easiest once you get things lined up to use the arm that disengages the clutch to "pull" the cover back on. If you get things lined up right, you can twist that arm and it will pull the cover on straight and right. It's a good way to tell if everything is lined up right.
Sorry, that's all I remember off the top of my head (oh yeah, you will need an 8MM socket, not a 12, and disconnect the electronics via the plug under the bodywork, don't pull the sensor...)
