ignition
I currently run a '72 Combat Roadster with points. Although I have no experience with Rita or Boyer, I can say that starting and running is fine; this bike runs like the devil and doesn't miss a beat. I believe that people often confuse hard starting due to carburetion with ignition problems. Learning the subtleties of each different machine, just how much to tickle those Amals, seems to me to be the essence of starting a Norton. I have had a '70 Roadster since 1974, driven it across the country etc. and my only complaint about points ignition is that once the points cam seal wears they are prone to getting oil mist that can indeed make for hard starting or misses. Even on a road trip you could place a little piece of cotton or tp in the bottom of the points cover to absorb any oil, and you're fixed. I'm not sure how "serviceable" electronic ignitions are. SUMMARY: points can work great and are serviceable; if I had electronic I'd carry back-up points on a road trip for emergency repair.
