Answer
Justin, I see that you have a "late" Dream, which is probably stamped C78 on the chassis. The earlier version C(A)77 chassis (1960-62/3) had a dual-tower coil with replaceable high tension leads, but after that the coils were encapsulated and had the leads as a part of the coil body. People have been known to cut the terminals back enough to remove the wire leads, which leaves a hole with spike terminal tip protruding. New solid-core wires can then be pushed into the recesses and then a high temp RTV-silicone sealer used to secure them in place.

In a recent search for a coil for my Type 2 CL72, I ran across coils from the XS650 site which offers an aftermarket 4.5 ohm coil for about $50. The Yamaha XS650s had two choices for coil setups, twin coils or a single dual-lead unit.

This is a long-standing issue with the newer Dreams, so there is a big demand for the earlier coils or suitable replacements.

Item # 200812692481  with reservations as the coil has a 2.5 ohm primary resistance, which may overheat in service with points/condenser ignition. They are claiming that the coil will work for 250-305 twins, however.

I had to re-edit the URL as the allexperts system was truncating the whole line, cutting off the item numbers. Hopefully, it goes through completely when I hit SEND.
