Welcome home.
Wether it's an easy fit depends mostly on what kind of '92 GSX-R750 you're talking about. The oilcooled one, we call it "Slingshot", or the watercooled one which 'Murica didn't get until 1993 but the rest of the world had in 1992.
Oilcooled: straight fit, watercooled: quite some surgery needed.
