okay, here is a question that nobody wanted to answer somewhere else so let me ask you guys. Will a #25 chain work on a Chinese bike kit sprocket. I would like to use a 350 watt electric engine along with a chain drive. The kit type sprocket with pads seems like a good idea to me if the #25 chain will fit it. If not its back to the drawing board. So if you have a #25 chain and a sprocket from the kit would you check to see if it will work. I hate to buy a chain just to find out that one thing, when someone else might know or have a piece of chain they can check it out with. This is the kind of thing you can't get answered anywhere else so thanks if anyone can help.
