kz-550 Decently Extreme Backfiring

I was thinking about electronic ignition. Im not entirely sure how it works but Ill take a look into it. Any ideas on how the ones on Z1 are? They are like 8 bucks per point, and I cant imagine the condensers are too expensive either. I had an extra set of points that I threw together, I got 2 and 3 firing when 1 and 4 started creating big blue sparks. Safe to say, this is my least favorite part of working on these things!
