i purchased this machine as a parts bike. i decided to put it together and looking at the stator coils, there are two, i noticed one, the one with the finest wires, had a broken wire. is this for the ignition? will the machine have a spark with just the coil with the larger wires working? can this part be bought anywhere? i,ve been searching and found a single coil for sale but not the pair, and i don't know which coil it was by the picture. help!
