Both my indian 'iron' Bullets - a 350 and a 500 run their original points systems. My Triumph Trident, although unused for many years, has three sets of points. My Honda CB500T has two sets of points. All my Tiger Cubs have points. I could go on, but you should see a pattern here. I would, however, fit, say a Boyer system if I was rebuilding a machine and the ATU, points back plate, condenser etc were all missing or badly worn, as there is little difference in price between the two complete set ups bought new. I also recently had a Honda 500 four in because it was running rough and misfiring. The points and all other ignition components were like new, but the owner handed me an electronic ignition system he wanted me to fit, to 'fix' it. I fixed it by taking out his resistor plugs, which, in conjunction with his resistor plug caps turned out to be the cause of all his problems. Ordinary plugs provided a cure. If it ain't broke, don't fix it, has always been my approach. If a points system is in good shape and set up correctly, I don't see what there is to be gained by ripping it out and replacing it with an electronic system - the only exception for me is the self generating, crankshaft fitted types for the Bullets, which we have on our racers, as it is possible to get much more precise timing, without having to go through all the backlash in the train of gears normally used to spin the distributor - or magneto on these machines. I once strobed an 11 degree fluctuation here on one magneto equipped machine, which would still have been present if it could have been fitted with a Boyer.
