well what size are your sprockets? Are they 415? 41? 40? If it is the sprocket that comes with the standard motorized bike kit, it is most likely a 415

Here is a chain size chart that might help. If you are trying to put a 40 chain on a 415 sprocket, I don't think it will fit.

If you're trying to do it for strength, you may be able to run a 420 chain. I think that is what I've got. You may need to clearance the motor a little for 420 though.
