I rest my case for the points triggered CDI. 2 minute job to swap back to standard and superb starting / sparking  characteristics & maintains the standard coils !!

Not sure on Hondaman's I suspect it is a transistor switched coil device. Has a good name to it though.

Cheers .... Ash D

Hi All,
"During the War" er no not quite that far back Lol!, i did fit boyer to me Commando 850 interstate, with no coil swap over, & later to a Gs750 i had, same ran it with standard coils, no probs.
Have heard of the Hondaman system, has anyone got it fitted?.
Stumbled on something called Newtronic ignition somewhere on the web, but as happens annoyingly sometimes, cant find it again grrrr!.

Fitted Newtronic system to the CB550F just after I got it in 1992-never had a moments trouble with it in 23000 miles. Still works down to 10.5 volts. Easy to put back old system if required.

I guess what makes it a 50/50 decision is that there is nothing fundamentally wrong with the standard points setup so you're not comparing a significant advance with a crap starting point as some mods will accomplish.

For most people that look after older engines then if you just had a box of components for the points system then they could assemble it all and time it with a fag paper (i appreciate that means something else to USA readers) and get the engine to run quite well.....hence the roadside ease of use case.

The electronic systems all seem to be reliable as well....but if the bike does stop it's just harder to establish which bit is stopping it...it'd be rare for either system to leave you stranded though in my experience.

Magnetic triggers to me have always performed reliably in a number of differning applications, it's more often that the amplification circuitry gives problems and sometimes seem prone to the effects of heat and vibration.

One of the biggest advantages of a better ignition system I believe is the potential to run the jetting leaner.....giving a cleaner burn, less oil contamination (especially at starting) and dryer exhaust pipes....all quite relevant to looking after these old bikes and preserving their condition longer term.
