Honda points last forever and in my experience hardly require any maintenance. I got my bike with 33.000km on the odometer. I doubt that I - now a ton later - have ever replaced them more than once. That's why these EI advertisements - 'set and forget' - has always made me laugh. Honda points are almost set and forget. Just check every 3000 km that the little felt at five o'clock under the advancer cam does not run dry. Just a drop of oil. It is true: stock points are expensive, so one might consider an EI. That has to be one of a brand with a spotless reputation. Having followed thousands of threads in various SOHC fora, I have not met one brand that never ever gave a problem. That's why some 20 years ago I decided to build a transistor ignition module - similar to Hondamans I suppose - myself. Points are still there but now just trigger the power transistor. See this setup as a relay. In the event of a malfunction, I can switch back to 'old style' anytime, but the system has worked flawlessly all these years. Points will not pit anymore and mine are now close to 60.000 kms in service. When you decide for an EI, don't expect even one HP more. If you, after you have fitted an EI, 'feel' the bike 'really' runs better, it probably has more to do with the fresh sparkplugs you have fitted, 'to do the job a 100% rightaway' but... - who knows - secretly to avoid a possible dissappointment...
