It could be a lot of things BAOLA. Just to save time, whenever I am working on a bike with points and it isn't running right, the first thing I check is the points. Chances are there's your trouble. There are a lot of good reasons why even lawn mowers no longer use points.

Interesting. I have never heard nor read any documents or experienced that higher cylinder pressures require more spark plug energy. Heat, on the other hand, will. The two are interrelated because of the gas in the cylinder. But, at 80 mph, heat is not a big problem.

Regardless (or irregardless), the primary ignition circuit is in no way affected by the transmission gear or engine temperature. So, looking for gremlins in the dyna booster will not be productive, IMO. Good luck!
