I went with Power Arc from Old Britts. 7,000 miles later and still ticking like a clock.

Powerarc triple sparkler vs the rest of the world. Fill yourselves in let me...

Whichever you choose fit a fuse in-line to protect it . And the groundpoint must be solid . Electronics don't like certain things. What comes to mind ? Heat,vibration,poor grounds,accidentally reversed polarity (+ -). I have experience with the B. one. Like pushing along the highway to the next exit. :roll:

Duh a fuse will not protect anything but the wires to and from a component but not the component. i suppose its possible in an electronic ign. system shorted inside it could melt or burn its wire supply, but I hightly doubt it. Lights and horn to and from battery for sure .
For the money, it's hard to beat the Pazon SureFire. Although the control box is mounted up under the tank, it is small. A 7 1/2 year warrentee, who the hell else does that. At some of our ages, that's a life time guarentee.
No bells and whistles with these, only solid functionality. Your could almost buy 3 of them for the price of one of the self contained units. That's 22 1/2 year worth of warrentee.
I have never had a problem with mine and yet to hear a bitch about them on the forum. I run a mag now because I can, but will never get rid of the surefire. It's nice to know it is there if needed. I had an issue with a pinched wire on the mag that i failed to ID. The Pazon unit was there when i needed it.
If it was not for the mag being so awesome, I would venture to try the Altair.
The one thing I like about the Trispark is that it is pretty.

I and a few others had Pazion Sure that tested completely perfect on half dozen exams they list yet failed to fire. Some turned out to be the cam end fit spacing magnets wrong so corrected by mechanics solution only after some tedious measuring w/o any electrics involved. Still don't know why mine failed but had help to make sure triple quadruple check and then some more - it wasn't my fault. Powerarc has failed in some d/t cam fit stability and a special conical adapter made available at least for a short run while offering was hot on the griddle. Commando's are simple machines not for the simple minded, which of course is why I got and get caught out by them routinely.

Some of you have heard this before... :roll:. I was a long time Boyer user since the '70s and decided to upgrade. I like Pazon. I went with the Pazon Altair when it was first announced. This is a cut above the Sure-Fire because it has an idle stabilization circuit like the Tri-Spark. And it is more expensive so it must be better. (I did put a Pazon Sure-Fire on my '61 Matchless and it has been fine.) IMO the Pazon Altair is likely as good performance-wise as the Tri-Spark but somewhat cheaper. Cheapest is to buy it direct from Pazon HQ in New Zealand.
I had a bad experience with one of the first Boyers which had the electronics in the points cavity. When hot it went nuts. They replaced it free with the Mk I which was similar to the MK III version. The electronics are remote under the tank. I ran that for 35 years. However the Altair was a surprisingly huge improvement and really opened my eyes. I was a diehard Boyer fan until then. Previous threads show the advance curves for each type. Lots of earlier discussion on this subject. EVERYONE WILL DEFEND TO THE END WHATEVER THEY BUY so do the research and just pick one that fits your budget.

I went with the Power Arc. It helped me get my "barn find" MKIII running after sitting for 20+ years. I had troubleshooting difficulties, limited time to devote to the problem and limited garage facilities, so I went with the power arc because it is a complete all inclusive system. Bike started right up 
....carbs were crapped out so it didn't run long but that's another story....JSmotorsports flat slide fixed that one.

My bike came with a Boyer and I had idle problems and backfire problems while starting ...I purchased the Trispark ignition and their 6v coils and now my bike does not backfire during startup and idles while stopped very well....If in US these people are great to deal with and the prices are right....

This is the reason why I would think twice about fitting a TriSpark, I really don't think that the Norton points cavity is a sensible place to locate your electronics module, too much heat and vibration for longetivity, however well the unit is manufactured.
Many digital electronic ignitions do require plug caps with resistors, and always match the ignition to the coils being used.

I'm not an electronics engineer, so am speaking as a layman, but I do know that electronics have come on a long way in recent years. As an example, look at coils, we mount them in the wind to prevent over heating... Many modern bikes and cars have the coils built into the plug caps and fit them direct to the plugs, deep in the cylinder head, the hottest part of the engine! And they don't fail!
I'm going to put my money on the fact that Tri Spark know what they're doing, and will be fitting one to my 850 (along with a CNW Accel coil).
I've never fitted Tri Spark to a twin before i confess, but have used them on Triumph / BSA triples with great success.
On a 988cc tuned engine, back to back Dyno tests when replacing a Boyer with 4 volt coils, for a Tri Spark with 12 volt Dyna coils, resulted in a 5 BHP gain and a 7lbs peak torque gain. Plus it gave a broader flatter power band, and started and idled better.
'twas difficult for me to fault really!
