Probably not. I bought a Dyna Booster on a whim, but my '78 points cost ~$20.00/set and the booster was $80.00 shipped. The '79 model points have a VW equivalent which is less expensive and easier to find.
I don't think the spark is any better with the Dyna Boost, the gadget just extends the life of the points - provided the electronics don't die. But, don't let me dissuade you from wasting money on a motorcycle gadget.
