520 off set primary sprocket 4 wide tire on BUSABANDIT ?

[Daytona]

Hey anyone know where i can get an off set 520 primary sprocket for Bandit / Busa / Gixxer etc? 17 or close teeth, I'm mounting an old wheel and tire I've had on the shelf using a moded swing arm but need all the room i can get! They make em but the folk that sell the wide tire kit ain't given up the MFG.
