I dont know how many of you do this, but i carry a small air compressor in a box, with tire plug repair kit.
It will get you out of a bind if you are out there and you get stranded.
I soldered a cigarette lighter outlet to the outlet in the right side cover panel there, where the 2 wires are for miscalanous use.
Compressor was about $20.00.
I got stranded once, and i can say, that unless you have a trailer or pick-up truck with ramps, it can be quite a chore.
I think that it is worth the small amout of space that it takes up.
The plugs do work, however they dont reccomend it for a fix, get you home though.
However i did ride mine on a plug for 9000 miles.
