Dyna coils

I was wondering if I can change out my coils and add a dyna system to my bike. I am not going to be racing it, well not at the track lol. Just basic getting on it on the long country roads. Would putting one of these units on make any bit of a difference on my 1983 1100 d2? My bike has a stage 3 kit in it and 4 into 1 exhaust. I do not know the age of my coils I just know that around 2000k it stumbles and I have been through the carbs over and over and it never changes. I have not stressed the coils to see if the are at fault yet. Just wanted to get some advise on these dyna set ups.

The factory kawi solid state ignition is a good one (if it's working right) but old coils do not age well. If they are old, kick em to the curb.
