Help with qs205 motor.

Hi guys first post, after some help if anyone out there has time. I need to fit a drive sprocket to the threaded side of the qs motor. It’s going to be used with a motorbike chain to become a mid mounted drive motor. If anyone has done this can you let me know what you used? Thanks.
