It's been a while, and I don't remember all the details, but we had to remove the tupperware from the front of the bike, the sides of the bike, and the top of the bike. You need to remove the cooling fan on the right side - it can be a chore to get it out, and back in. With the fan out of the way you can reach in and grab the sensor - we didn't have to drain the coolant, but a bit will leak out when you remove the sensor. Once you get it all back together you want to start the engine, WITHOUT TOUCHING THE THROTTLE. Let it idle until the fans come on and go off - this resets the engine computer. If you haven't drained the coolant, then some will have dropped onto the engine while you were swapping the sensor - this will generate copious amounts of steam while the engine is running; don't worry - it'll clear up!
I wish I had thought to take a bunch of photos to do a how-to article...
