Does anyone know the trans gear ratios and final drive ratio for a 90 gsxr750 (engine # R716) ? The Bandit I'm swapping it into currently has a 48-tooth rear sprocket and I'm trying to figure out the best gearing.

Thanks

This site doesn't go anywhere. I looked all over oldskoolsuzuki.info and could find any specs for a 750. any the factory service manuals section is disabled.

The gear ratio for that '90 GSX-R might be the way to go. 15/43 is stock if my info is correct. Troy341
