In 98 the 750 engines bore and stroke were changed to match the later model GSX
R oil cooled engines. There is a noticeable difference between the pre kat engines and the post kat engines in performance. Other than Cams and carbs... I don't know of a difference between the 92 GSXR engine performance wise vs the Post Kat engines. So cams and carbs could possibly make a huge difference, especially when your looking at a bike that is seriously "detuned".
