JohnG has the same answer as I. I bought the Andrews coils in the early 80s for my 1977 750k (836 kit, mild cam, ported and polished head, etc.) and they were simple to install. They are 3 ohm coils used mainly on Harleys, but work well on our motorcycles also. At the same time, I bought the 8 mm Accel spark plug wires from the same motorcycle parts store, but they are readily available at most auto parts stores. You will get a good powerful spark from this combination. I have a Maxi-Dwell points unit that utilizes Chevy V8 points, so it can handle the spark. Without the Maxi-Dwell, you may want to consider Hondaman's resistor/relay module to help your points handle the extra load.
