I carry a set of plugs too. I don't carry anything on my SM though since I have never had any problem with it at all.I have my cell to call a friend with a truck or tools if I ever need either. I do want to start taking my chain breaker though since any chain can fail.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
