Sur ron Motor sprocket size

Hello guys, i currently have a sur ron motor and wanted to install on there a sprocket for a 420 chain, however i need help finding one given the measurements. The diameter of the shaft is 20mm. And then the shaft is also missing what i think is called the key, and that measured to about 16mm as seen in the image below. Any help greatly appreciated.

Aebikes is located in New Zealand, so shipping would cost a lot, theres got to be someone in America that has it, and i dont need a kit that comes with the rear sprocket because i already have one.

surron dealers have the parts catalog, you can also find it on the facebook groups.. the stock motor comes with belt primary sprocket and an aftermarket chain conversion option.. doubt any dealers have just the motor chain sprocket available but maybe they could order it.. some dealers may have a better spare parts availability and responsive than others.. were did you get the motor, probably good place to start.. shipping shouldn't be much for small parts, even direct from china..

Appreciate your help, this isnt the first time youve helped me . I got the motor from Alan at ert he sent it to me with the bac 8000 controller. Hes rather busy ive tried contacting him. I guess ill contact aebikes or one of the other dealers and see if they can just send me the motor sprocket.
