I did the ST to G/ST conversion earlier this year. "La Suerte" is a 1983 ST with the following mods-
R100gs front end
Baja Designs headlight with boatman conversion
Enduralast Alternator upgrade
Bike works fantastic as a tourer, a long distance bike, and as a fire road bike. Completed a 6k mile trip around the west including the CDR from S to N.
Great bike. Still gotta finish my ride report...man, there's a lot to write about...
