Glad to see the forum is alive again!!!!!
I am looking for a sprocket for my powerpack "MAC" motor that will fit a bike chain.
I talked to Tim O'Brien at powerpack motors and he was VERY helpful! The bore is 12mm and it would need to fit a bike chain. Does anyone know where I might locate such a sprocket? Tim suggested that I use a #40 or #41 sprocket and bore it to 12mm, which would work but I was hoping that someone makes such a sprocket.
