Electronic ignition vs contact breaker assembly?

i have a 66' TR6.....i need new points....i recently started thread about availability of the original replacement points (4CA).......two problems, they are NOT available, and according to some of the experts, including Mr. Pete (who i value his experience and knowledge very much) they are "rubbish"

so i was encouraged to upgrade to a later style contact breaker system, which would involve some mods, (moving location of condensers, and possibly a different auto advance mechanism....

so, i'm wondering why not just change it all out to EI? is the Boyer system the way to go? are they hard to install? what are (if any) the disadvantages to going EI? keep in mind, that i don't ride my bike a lot, fair weather only, and short trips to work etc only...no road trips or anything on this bike. what say you all? Rick

EI

Personal choice, the brand that is. I have just wired up a Pazon unit. The underseat portion of the wiring is very straight forward and clear instructions are given with the unit. Connects to existing factory wiring. Two (bound) wires go to the timing disc that to is a very simple set up.
Made in New Zealand, just like Me!

I've had no issues with the all three Boyer's I've had in different bikes, but I can't speak for any others as I've never used them.
As to installation, it's not tough at all as long as you can extract the auto advance unit, it will be pretty simple.

Before the renovation, I ditched the contact breaker assembly, the old 12V coils, the old selenium rectifier and zener, in favour of Sparx units.

EI (advantages): easy to install, no parts to wear out, easy to set up, reliable, once set-up no further adjustment required. No mechanical contacts.
(disadvantages) : wiring routing can give problems, needs a good battery voltage. Two 6V coils recommended.

Points (advantages): Will work with a low battery voltage.
(disadvantages) contact breakers will wear, timing will need re-setting. Fiddly to set-up... both sides need to be timed. Mechanical parts and capacitors may fail.

There are lots of EI manufacturers, suggest you look at all of them with regard to cost, components and reviews. (search this forum)

Do youself a favour and also buy a solid-state Rectifier/regulator, then you throw away the old leaky selenium rectifier and zener diode.
[Loaded spark plugs or caps are required]

We did a survey here a while back, don't remember what the results were, though. Do a search and you'll find it.

I like Sparx, Pazon & Tri-Spark. Tr-Spark is best, but priciest.
