Carbs are Mikuni BST32, and Jay says that the kit for these bikes:
GSXR 750 (88)
GSX 750 F (89-94)
GSXR 1100 (89-90)
fit ours too. But googling for our carb doesn't show that those bike share, though we do share with 90~97 Katana 600's. He's got LOTS more experience with the B4/derivitives than I do, so I trust his word.. to the point that I've spent money on those float needles.
