Err, no. The 3/4 Spark plug socket isn't going to remove spark plugs on the FJR. Especially the newer '08-9 bikes.You might want to consider a spark plug wrench and socket extension that fits your front wheel. Or a piece of 3/4" rod coupling. With the spark plug wrench you can do plugs if needed and take off the front wheel.
I would vote for that same concept though, one of the compact 14/19mm axle tools and a wrench large enough to provide the leverage to remove axle nuts. With a correct socket for the spark plugs and extension. Needle nose pliers. Some extra fuses and generic hose clamps for fuel line. (there aren't any on the stock lines, but they come in handy for field repairs)
Equally important to first aid kits - WATER. I keep three half liter bottles in the saddle bag at all times. I've used them to clean out road rash and hydrate other riders I've come across that were having bad days. Never mind if you break down on a hot day somewhere w/o shade. Speaking of which, do you have a method of making shade on your bike? A cheap space blanket and Duct tape will do, but I carry an emergency shelter as well. Very compact at 5"x7"x 1/2". It lives in the bottom of the tank bag.
