These things can go at any time. You may have a few miles, or few hundred left. Buy a spare, it fits in the glove box, and easy to replace on the road. Upon your return, buy the points or, Dr Bean points replacment for the points, thats what goes bad. Then you always have a spare OEM pump thats intended for the bike. Plus the Dr. Bean might last forever.
