Re: Drive chain sprocket
Welcome to the forum...someone may be able to give you more insight to the sprocket problem. I have only heard of it once before. I think you could dremel out the area that the chain rubs on, but I'd wait for a more intelligent answer to that one.
Color coded wires....Blue to green or blue. Black to black. White wire is to be capped off and set out of the way as to not be grounded out, it's a wire to run a light with.
