Here are the tools you are supposed to have on your bike. (This list is from an 05...but I don't see why Honda would go cheap on a $50(??? This is how much they want to replace the tool kit) tool set.

There are only two tools that you really need from the tool kit though...the spark plug wrench and the spanner wrench for adjusting the shocks. You can use a strap wrench for adjusting the shocks, but the stock tool works pretty good when you use the handle extension...unless you have bags on your bike. Then it is pretty much useless.
Someone on here has found a replacement for the spark plug socket. I believe they used a regular socket and put the rubber spark plug tip holder in it. I don't remember what size you need though.
As for what tools you really need on the road...well, in the 56,400 miles I put on my 02 Spirit 1100, the only thing I have needed was a 10mm wrench to get the left side cover off when I killed the battery so I could get the bike jumped. I have also used the 10mm and the 5.5mm (I think that is right) to remove the seat when I bought my lambskin cover at the Honda Hoot (a few years ago).
If you are a boy scout and want to be always prepared (guilty of this too) and if you have saddlebags, go buy yourself a small tool kit that has the basic wrenches, screwdriver with straight and phillips, adjustable wrench, and pliers to carry with you on the bike. Then you can take care of the little things that come up while on the road. If you have the room, you can get a larger set, but the only reason you would need them is when you ride with your (other brand) riding buddies. :twisted: :twisted:
Just make sure your cell phone is charged when you leave the house on the bike.
