(The information in this post would serve well to be included in the tech library with the other coolant change information.)
I changed my coolant the other day for the first time. After reading all of the very helpful posts and the Tech Library, the only thing I noticed was that there were no tips on how to do it without creating a mess, especially when draining the cylinders. Sooo, I spent more time visualizing and figuring than I did actually draining the coolant, but I did come up with a method that resulted in no mess on the engine or floor. This will make my, and hopefully your, next coolant change a little easier and less messy.
As well, I found that at 2 inch long screw of the proper thread size was easier to use for pulling the cylinder side drain plugs than using the cumbersome spark plug.
I didn't repeat the steps on how to get to the radiator cap and how to remove of the side covers, as this information is already well documented in the tech library.

Get a 16 oz soda bottle, the type that is smooth sided because it flexes better. Cut an angle across the bottom end and cut out room for your fingers to pull the plug on the top side. You can do a few test fits with the bottle to get the angle right. You will need the cap screwed onto the bottle when you use it.

Put the bike on a jack and raise it high enough to clear a 5 gallon bucket. Remove the radiator cap, then the radiator drain plug and the radiator will speed dump with no mess.

Next, you will want to grab a large bath towel (preferably not the one your wife just bought at Kohl's). While I only dripped about 1 ounce of coolant onto the towel while draining cylinder 3, I used under the drain bottle on each cylinder to catch any dribbles (and this was the first time I tried this method and didn't know how well it would work).
Photos 3-5 illustrate how I placed the towel and the drain bottle for cylinders 1, 3, and 4. (I saved cylinder 2 for last, as it involves making a chute out of packing tape to flow the coolant to the bottle.) The drain plugs are in place in all of the pics, as I took the pics after I drained each cylinder. The coolant in the drain bottle is from the respective cylinder pictured.

The last step is draining cylinder 2. The location of the drain plug for cylinder 2 does not allow for the angling of the drain bottle. I saved this for last because it took a little construction of a chute made of packing tape. Tear three strips of packing tape long enough to go from the side of the cylinder to about 2 or 3 inches past the side of the chrome engine cover. One strip will be the middle strip with the sticky side down. The other two strips get folded in half lengthwise over the left and right third of the middle strip. Then abut one end of this tape contraption to the side of the cylinder and press the center portion down so it sticks to the top of the engine and along the groove of the chrome engine cover. You now have a little rain gutter to carry the coolant to your drain bottle.

My coolant drain amounts were as follows:
Radiator - 80 oz (2.5 qts)
Cylinder 1 - 5 oz
Cylinder 2 - 2 oz
Cylinder 3 - 2 oz (this accounts for the 1 oz that spilled into towel)
Cylinder 4 - 3 oz
Reservoir - 10 oz (was at the "Full" line)
Total - 102 oz (3.19 qts)
I didn't drain the water pump. Every post I've read and folks I have spoken with said they only got 4 oz, at most, out of the water pump and the headache of getting to the plug outweighed the amount of fluid I would get out.
Hope this has been of some help to others out there.
