I'm searching very hard for a number 410 chain drive sprocket for a common MY1020 motor (the silver brushless kind). Hasn't arrived, but I'm guessing it's a 10mm spindle with symmetrical flats (dual D). There's one crummy looking stamped sprocket on Amazon, plus the decent looking sprockets in 3 tooth sizes on ElectricScooterParts (for $20 each, shipped). Any other outlets for that? I don't find anything on eBay, and just the one on Amazon.

As posted before, I have a hack for a large rear sprocket. Have trouble finding scooter chain size rear sprockets that fit the MY1020 default T8F drive sprocket, for a freewheel hub, except the junk stamped stuff on Amazon.

Thank you.
