I had a very similar experience when I first got my Suzuki.
I was about 7 miles from home and the regulator/rectifier went out.
What sucked was that I couldn't get it to bump start since the battery was completely dead, and it was a pretty deserted road so no help from other motorists.
I ended up having to push it the 7 miles home in the midday sun.
I'll never forget that, but it sure was a good leg workout!
