Following the designation "Frankencarb" as the 380/550-carburettor conversion was called
in another topic, I now show my "FrankenFork"

Fork legs: GS550M Katana, mounted backside to front, to use with GT-calipers
steering stem: GT750
steering stem head: GT380, milled, to fit to the 35mm stanchions
Brake disks: GT250/380
