Question about 1985 Yamaha FZ 750 FN (Europe)
I recently purchased a yamaha FZ 750 FN that needs work. It seems like the problem is only one of the two cylinders is firing. I checked the plugs (both are new) and the running side fires plenty hot and the bad side seems to make little to no spark. Replacing the rectifier was suggested to me, does that sound like a good place to start? Also what about a coil. It is a single coil with 2 plug wires so it seems like if it were the coil, it wouldn't fire at all. Thanks for the help.
Switch plug wires and see if the dead cylinder starts firing --if it does you need new wires
