I checked the basics first, pulled the plugs, 2 nd 3 were wet. Checked fire across the board and Wala, middle cylinders dead. First thought bad coil, also thought first bad stock 750 coil I have ever seen. Tank came off and there sat an unplugged black/white wire going to coil 2/3. When I zip tied the wires it must have not been plugged tight and came free. Cleaned the plugs, dropped the tank back on, and I have to confess, the best running 750 I have ever sat on. Fast, pulls like a freight train, and shifts smooth as butter. Of course there are some little fixes pending, got one weeping carb and I think a new petcock might be needed, but this is going to be a good running motorcycle. I really may have to think what bike I am going to sell.....
